In Japanese, the word for 'researcher' is けんきゅうしゃ (kenkyūsha). It's a word you might hear when people talk about scientists or people who study things very carefully. For example, if someone is working in a lab and trying to find new medicines, they are a けんきゅうしゃ. It's a bit like saying 'someone who does research'. You don't need to know this word when you are just starting to learn Japanese, but it's good to hear it.
The Japanese word けんきゅうしゃ (kenkyūsha) means 'researcher'. This is someone who studies something very deeply, like a scientist in a laboratory or a historian looking at old books. Think of it as a person whose job is to find out new things or understand difficult topics. You might hear this word when people talk about universities or science. It's a word for people who work hard to learn and discover.
The term けんきゅうしゃ (kenkyūsha) is the Japanese word for 'researcher'. It refers to an individual who conducts systematic investigations or studies, typically in an academic, scientific, or professional context. This can include university professors, scientists in research institutions, or specialists in various fields who are dedicated to discovering new knowledge or analyzing complex information. The word is formed from けんきゅう (kenkyū), meaning 'research,' and しゃ (sha), meaning 'person' or 'specialist.' You'll encounter this term when discussing academic careers, scientific breakthroughs, or professional roles focused on in-depth study.
けんきゅうしゃ (kenkyūsha) is the standard Japanese term for 'researcher'. It denotes a professional engaged in systematic inquiry, investigation, and analysis within a specific domain. This term is commonly used in academic settings (universities, research institutes), R&D departments of companies, and any field where rigorous study is paramount. It implies expertise and a dedicated pursuit of knowledge, whether in sciences, humanities, or social sciences. The word is composed of けんきゅう (kenkyū - research) and しゃ (sha - person), highlighting the role of the individual in the research process. Understanding kenkyūsha is crucial for comprehending discussions about academic achievements, scientific progress, and specialized professional roles.
In Japanese, けんきゅうしゃ (kenkyūsha) functions as the precise designation for a 'researcher.' This term encompasses individuals who undertake systematic, in-depth studies and investigations, typically within academic, scientific, industrial, or specialized professional environments. It signifies a role characterized by intellectual curiosity, analytical rigor, and a commitment to advancing knowledge or developing new insights. The etymological breakdown, けんきゅう (kenkyū: research) + しゃ (sha: person/specialist), clearly defines the individual's function. Its usage spans formal academic discourse, scientific publications, policy discussions, and professional profiles, indicating a level of expertise and a focused contribution to a particular field.

  • けんきゅうしゃ (kenkyūsha) means researcher.
  • It refers to someone who conducts systematic studies or investigations.
  • Commonly used in academic and scientific contexts.
  • Combines 'kenkyū' (research) and 'sha' (person).

The Japanese word けんきゅうしゃ (kenkyūsha) directly translates to 'researcher' in English. It refers to a person who conducts research, investigations, or studies, typically in an academic, scientific, or specialized field.

Breakdown
The word is composed of two parts: けんきゅう (kenkyū), meaning 'research' or 'study', and しゃ (sha), a suffix that denotes a person or specialist (like in igakusha - doctor, or shakusha - engineer).
Contexts of Use
You will commonly encounter kenkyūsha when discussing academic institutions like universities (daigaku - 大学), research laboratories (kenkyūjo - 研究所), scientific discoveries, or any professional who dedicates their work to in-depth investigation and analysis. It's a formal term used in professional and academic settings.

She is a dedicated けんきゅうしゃ in the field of marine biology.

It's important to understand that kenkyūsha implies a level of expertise and a systematic approach to inquiry. It's not just someone who is curious; it's someone whose profession or significant endeavor involves rigorous research.

Examples might include scientists working on new medicines, historians examining ancient texts, or social scientists studying societal trends. The term encompasses a broad range of intellectual pursuits.

Synonymous Concepts
While 'researcher' is the direct translation, the nuance can sometimes be closer to 'investigator', 'scholar', or 'analyst', depending on the specific context of their work.

The university hired a new けんきゅうしゃ for its artificial intelligence department.

The word is neutral in terms of gender and age, referring to anyone engaged in research activities professionally.

Using けんきゅうしゃ (kenkyūsha) in sentences is straightforward, typically following standard Japanese sentence structure. It often appears as the subject of a sentence, the object of a verb, or as part of a descriptive phrase.

As a Subject
When kenkyūsha is the subject, it performs the action. Common verbs used with it include suru (to do), tsutomeru (to work/be employed), or verbs related to their research activities.

その けんきゅうしゃ は新しい発見をした。

Sono kenkyūsha wa atarashii hakken o shita.

That researcher made a new discovery.

As an Object
It can also be the object of a verb, for example, when talking about interviewing or collaborating with a researcher.

私達は優秀な けんきゅうしゃ を探している。

Watashitachi wa yūshū na kenkyūsha o sagashite iru.

We are looking for an excellent researcher.

Describing Someone's Role
It can be used in phrases to describe someone's profession or title.

彼女は大学の けんきゅうしゃ です。

Kanojo wa daigaku no kenkyūsha desu.

She is a university researcher.

Common sentence patterns involve stating where a researcher works or what their field of study is.

Field of Research
You can specify the area of research using particles like ni oite (において) or simply by placing the field before kenkyūsha with no.

彼は物理学の けんきゅうしゃ として有名です。

Kare wa butsurigaku no kenkyūsha toshite yūmei desu.

He is famous as a physicist researcher.

Consider the context: are you talking about a specific researcher, researchers in general, or the role of a researcher?

Pluralization
Japanese often omits explicit plural markers when the context makes it clear. However, if you need to emphasize plurality, you can use terms like tachi (たち) or ra (ら) after kenkyūsha, though this is less common for this specific word in formal writing.

多くの けんきゅうしゃ が会議に参加した。

Ōku no kenkyūsha ga kaigi ni sankashita.

Many researchers participated in the conference.

You'll encounter the word けんきゅうしゃ (kenkyūsha) in a variety of settings, mostly related to academia, science, and professional fields that involve deep investigation and analysis. Understanding these contexts will help you grasp its usage more intuitively.

Academic Institutions
Universities (大学 - daigaku) and graduate schools are prime locations for hearing kenkyūsha. Professors, post-doctoral fellows, and senior researchers often hold this title. You might hear it in discussions about university faculty, research projects, or academic conferences.

この大学には多くの著名な けんきゅうしゃ がいます。

Kono daigaku ni wa ōku no chomei na kenkyūsha ga imasu.

This university has many renowned researchers.

Research Laboratories and Institutes
Government research institutes (研究所 - kenkyūjo), corporate R&D departments, and private research foundations employ many kenkyūsha. News reports about scientific breakthroughs or technological advancements often mention the researchers involved.

新しい治療法を開発するために、多くの けんきゅうしゃ が協力している。

Atarashii chiryōhō o kaihatsu suru tame ni, ōku no kenkyūsha ga kyōryoku shite iru.

Many researchers are collaborating to develop a new treatment method.

Media and Publications
Academic journals, scientific magazines, news articles discussing research findings, documentaries about scientists, and even job postings for research positions will frequently use kenkyūsha. When reading about advancements in fields like medicine, technology, or social sciences, this term is likely to appear.

その けんきゅうしゃ は、長年にわたる研究の成果を発表した。

Sono kenkyūsha wa, naganen ni wataru kenkyū no seika o happyō shita.

That researcher announced the results of their long-term research.

You might also hear it in conversations where people are discussing their career aspirations or the work of colleagues in specialized fields.

Conferences and Symposia
At academic conferences, presentations are often given by kenkyūsha, and their titles or affiliations will be mentioned. This is a very direct context for hearing and understanding the word.

この分野の第一人者である けんきゅうしゃ が講演を行う。

Kono bun'ya no daiichininsha de aru kenkyūsha ga kōen o okonau.

A leading researcher in this field will give a lecture.

While けんきゅうしゃ (kenkyūsha) is a relatively straightforward term, learners might make a few common mistakes when using or understanding it. Being aware of these can help prevent misunderstandings.

Confusing with General Students
A common error is to use kenkyūsha to refer to any student, especially undergraduate students. While graduate students conducting thesis research might be considered kenkyūsha in a broad sense, the term specifically implies a professional or dedicated investigator. A typical student is usually referred to as gakusei (学生).

Incorrect: 彼は大学の けんきゅうしゃ です。

(If referring to a regular student)

Correct: 彼は大学の学生です。

Kare wa daigaku no gakusei desu.

He is a university student.

Overuse in Casual Conversation
Kenkyūsha is a relatively formal term. Using it in very casual conversations when a simpler term would suffice might sound a bit stiff or overly academic. For instance, if you're talking about someone who is simply curious about a topic, kenkyūsha might not be the best fit.

Overly Formal: 私はこの問題の けんきゅうしゃ です。

(If the context is casual curiosity)

More Natural: 私はこの問題にとても興味があります。

Watashi wa kono mondai ni totemo kyōmi ga arimasu.

I am very interested in this problem.

Misinterpreting the Scope of 'Research'
The term 'research' can be broad. Sometimes, people might think of kenkyūsha as someone only working in hard sciences (physics, chemistry). However, the term applies equally to humanities (history, literature), social sciences (sociology, psychology), and even fields like art history or economics, as long as the work involves systematic investigation and analysis.

Incorrect Assumption: 彼は科学者だから けんきゅうしゃ だ。

(This is true, but incomplete)

Correct Understanding: 文学史の けんきゅうしゃ もいる。

Bungakushi no kenkyūsha mo iru.

There are also researchers of literary history.

Grammatical Errors
While less common for this specific word, learners might occasionally misuse particles (like は, が, を) or confuse it with similar-sounding words. Ensure you understand the grammatical function of kenkyūsha in the sentence.

Incorrect Particle Use: 彼は けんきゅうしゃ に研究している。

(Implies he is researching *into* a researcher)

Correct Particle Use: 彼は けんきゅうしゃ として研究している。

Kare wa kenkyūsha toshite kenkyū shite iru.

He is researching as a researcher.

While けんきゅうしゃ (kenkyūsha) is the standard term for 'researcher', Japanese offers other words that might seem similar or can be used as alternatives depending on the context and nuance you wish to convey. Understanding these differences is key to precise communication.

研究者 (kenkyūsha) vs. 研究員 (kenkyūin)
研究員 (kenkyūin) also translates to 'researcher' or 'research staff'. The distinction is subtle. Kenkyūin often refers to someone employed as a researcher in a specific institution, like a research institute or a company's R&D department. It can sometimes imply a more defined, perhaps less senior, role than kenkyūsha, which can encompass a broader range of individuals, including professors leading research groups. However, in many practical contexts, they are used interchangeably.
TermNuanceExample Usage
研究者 (kenkyūsha)General term for anyone conducting research; can include professors, independent scholars, etc.大学の研究者 (daigaku no kenkyūsha - university researcher)
研究員 (kenkyūin)Often implies an employed researcher in an institute or company.研究所の研究員 (kenkyūjo no kenkyūin - research institute researcher)
研究者 (kenkyūsha) vs. 学者 (gakusha)
学者 (gakusha) translates to 'scholar' or 'learned person'. While many scholars are researchers, gakusha emphasizes knowledge, erudition, and often a broader engagement with a field of study, perhaps including teaching and writing extensively. A kenkyūsha is primarily defined by their research activities. A professor (教授 - kyōju) is often both a kenkyūsha and a gakusha.

She is a renowned scholar in Japanese literature.

彼女は日本文学の著名な がくしゃ です。

Kanojo wa Nihon bungaku no chomei na gakusha desu.

研究者 (kenkyūsha) vs. 専門家 (senmonka)
専門家 (senmonka) means 'expert' or 'specialist'. While a kenkyūsha is usually an expert in their field due to their research, senmonka is a broader term. Someone could be a senmonka due to extensive practical experience, not necessarily through formal research. For example, a seasoned chef might be a senmonka of cuisine, but not necessarily a kenkyūsha.

He is an expert in international law.

彼は国際法の せんもんか です。

Kare wa kokusaihō no senmonka desu.

研究者 (kenkyūsha) vs. 探偵 (tantei)
探偵 (tantei) means 'detective' or 'private investigator'. While both involve investigation, tantei implies uncovering facts for legal or private matters, often involving surveillance or detective work, whereas kenkyūsha is focused on systematic, often academic or scientific, inquiry to gain knowledge.

The detective solved the case.

その たんてい は事件を解決した。

Sono tantei wa jiken o kaiketsu shita.

How Formal Is It?

Fun Fact

The suffix 'sha' (者) is derived from the Chinese character for 'person' and is used in many Japanese words to indicate a profession or role, similar to how '-er' or '-ist' is used in English (e.g., 'teacher', 'scientist'). The combination highlights the individual's dedication to the act of research.

Easily Confused

けんきゅうしゃ vs 研究員 (kenkyūin)

Both terms translate to 'researcher' and are used in similar contexts.

<em>Kenkyūsha</em> is a more general term for anyone engaged in research, including professors and independent scholars. <em>Kenkyūin</em> often refers to someone employed as a researcher within a specific institution like a research institute or a company's R&D department. The nuance can be subtle, with <em>kenkyūin</em> sometimes implying a more defined, perhaps less senior, role, but they are often used interchangeably in practice.

大学の<strong>研究者</strong>は新しい理論を提唱した。(Daigaku no <strong>kenkyūsha</strong> wa atarashii riron o teishō shita.) - A university <strong>researcher</strong> proposed a new theory. / 研究所の<strong>研究員</strong>が、この実験を担当しています。(Kenkyūjo no <strong>kenkyūin</strong> ga, kono jikken o tantō shite imasu.) - A <strong>research staff member</strong> at the institute is in charge of this experiment.

けんきゅうしゃ vs 学者 (gakusha)

Both terms relate to intellectual pursuits and knowledge.

<em>Gakusha</em> (scholar) emphasizes deep knowledge, learning, and erudition, often associated with academic mastery and broad understanding of a field. <em>Kenkyūsha</em> (researcher) specifically denotes someone actively engaged in systematic investigation and discovery. A scholar might be a researcher, but not all researchers are necessarily considered scholars in the same vein. The focus of <em>gakusha</em> is on learnedness, while <em>kenkyūsha</em> is on the process of research.

彼は古典文学の<strong>学者</strong>として有名だ。(Kare wa koten bungaku no <strong>gakusha</strong> toshite yūmei da.) - He is famous as a <strong>scholar</strong> of classical literature. / 彼女は現代史の<strong>研究者</strong>であり、多くの論文を発表している。(Kanojo wa gendai-shi no <strong>kenkyūsha</strong> de ari, ōku no ronbun o happyō shite iru.) - She is a <strong>researcher</strong> of modern history and has published many papers.

けんきゅうしゃ vs 専門家 (senmonka)

Researchers are typically experts in their fields.

<em>Senmonka</em> (expert/specialist) refers to someone with a high level of knowledge or skill in a particular area. This expertise can be gained through formal research (making them a <em>kenkyūsha</em>), but also through extensive practical experience, training, or years of work in a field. A <em>kenkyūsha</em> is usually a <em>senmonka</em>, but a <em>senmonka</em> is not necessarily a <em>kenkyūsha</em>. The term <em>senmonka</em> is broader and encompasses practical expertise as well as academic knowledge.

そのシェフはフランス料理の<strong>専門家</strong>です。(Sono shefu wa Furansu ryōri no <strong>senmonka</strong> desu.) - That chef is an <strong>expert</strong> in French cuisine. / 彼はAI分野の<strong>研究者</strong>として、最新技術を開発している。(Kare wa AI bun'ya no <strong>kenkyūsha</strong> toshite, saishin gijutsu o kaihatsu shite iru.) - He, as a <strong>researcher</strong> in the AI field, is developing the latest technology.

けんきゅうしゃ vs 探偵 (tantei)

Both involve investigation.

<em>Tantei</em> (detective) investigates to uncover facts, often related to crimes or missing persons, usually for legal or private purposes. Their methods can involve surveillance and evidence gathering in a practical, often clandestine, manner. <em>Kenkyūsha</em> (researcher) investigates systematically to gain knowledge, understand phenomena, or develop theories, typically in academic or scientific settings. The goal of a <em>kenkyūsha</em> is knowledge creation and understanding, while a <em>tantei</em>'s goal is fact-finding and resolution of specific cases.

警察の<strong>探偵</strong>が事件の真相を追っている。(Keisatsu no <strong>tantei</strong> ga jiken no shinsō o otte iru.) - The police <strong>detectives</strong> are pursuing the truth of the case. / 彼は宇宙物理学の<strong>研究者</strong>として、星の形成過程を調べている。(Kare wa uchū butsuri-gaku no <strong>kenkyūsha</strong> toshite, hoshi no keisei katei o shira-bete iru.) - He, as a <strong>researcher</strong> of astrophysics, is studying the process of star formation.

けんきゅうしゃ vs 学生 (gakusei)

Graduate students can be involved in research.

<em>Gakusei</em> (student) refers to anyone enrolled in an educational institution, from elementary school to university. While graduate students (especially doctoral candidates) often conduct research and can be considered researchers in training or even fully-fledged researchers, the term <em>kenkyūsha</em> typically implies a professional role beyond just being a student. It suggests an independent investigator, a professor leading research, or a dedicated staff member whose primary role is research.

<strong>学生</strong>は図書館で勉強している。(<strong>Gakusei</strong> wa toshokan de benkyō shite iru.) - The <strong>student</strong> is studying in the library. / その大学の<strong>研究者</strong>は、新しい治療法を発見した。(Sono daigaku no <strong>kenkyūsha</strong> wa, atarashii chiryōhō o hakken shita.) - <strong>Researchers</strong> at that university discovered a new treatment method.

How to Use It

frequency

High in academic and scientific contexts, medium in general news and professional discussions.

Common Mistakes
  • Using けんきゅうしゃ for any student. 学生 (gakusei)

    けんきゅうしゃ refers to a professional researcher, not a general student. For students, use 学生 (gakusei), especially for undergraduates. Graduate students conducting thesis work might be considered researchers, but the term <em>kenkyūsha</em> implies a more established professional role.

  • Confusing けんきゅうしゃ with 学者 (gakusha). 学者 (gakusha) for 'scholar', けんきゅうしゃ (kenkyūsha) for 'researcher'.

    学者 emphasizes learnedness and broad knowledge, while けんきゅうしゃ emphasizes the act of systematic investigation. While there's overlap, they are not always interchangeable. A scholar is often a researcher, but the terms highlight different aspects.

  • Using けんきゅうしゃ in very casual conversation. Use simpler terms or descriptive phrases depending on the context.

    けんきゅうしゃ is a neutral to formal term. In casual talk, describing someone as 'interested in studying things' or using their specific profession might be more natural than calling them a <em>kenkyūsha</em> unless they are indeed a professional researcher.

  • Misinterpreting the scope of 'research'. けんきゅうしゃ applies to humanities and social sciences too.

    Some learners might assume けんきゅうしゃ only applies to scientists in labs. However, historians, literary critics, sociologists, etc., are also <em>kenkyūsha</em> if they conduct systematic research in their fields.

  • Incorrect particle usage with けんきゅうしゃ. Ensure correct particles like は, が, の, and として are used.

    For example, using '大学<strong>の</strong>研究者' (daigaku <strong>no</strong> kenkyūsha) for 'university researcher' is correct, while other particle combinations might lead to grammatical errors or altered meanings.

Tips

Master the 'Kyuu' Sound

The 'kyuu' sound in けんきゅうしゃ (kenkyūsha) is a long vowel sound, similar to the English word 'cue'. Make sure to hold the sound slightly longer than a short 'kyu' to pronounce it correctly. Practice saying 'ken-kyuu-sha' slowly.

Associate with Academic Settings

When you hear けんきゅうしゃ, immediately think of universities, laboratories, academic journals, and scientific discoveries. This association will help you remember its meaning and appropriate usage.

Break Down the Word

Remember that けんきゅう (kenkyū) means 'research' and 者 (sha) means 'person'. So, けんきゅうしゃ is literally a 'research person'. This breakdown makes the word's meaning very clear.

Use in Formal Contexts

For learners, it's safest to use けんきゅうしゃ in formal or semi-formal contexts, such as when discussing academic careers, scientific news, or professional roles. Avoid using it in very casual, everyday conversations unless the context clearly calls for it.

Learn Related Terms

Learning words like 研究 (kenkyū - research), 研究室 (kenkyūshitsu - laboratory), and 論文 (ronbun - paper/thesis) alongside けんきゅうしゃ will provide a richer understanding of the research environment and its associated vocabulary.

Visualize the Researcher

Create a mental image of someone deeply focused on their work, perhaps in a lab coat, surrounded by books or equipment. This visual aid can help solidify the meaning of けんきゅうしゃ.

Master Particle Usage

When using けんきゅうしゃ in sentences, pay close attention to particles like は (wa), が (ga), and の (no). For example, '大学の研究者' (daigaku no kenkyūsha) means 'university researcher', showing affiliation.

Distinguish from 'Gakusha'

Remember that while a scholar (学者 - gakusha) is often a researcher, gakusha emphasizes learnedness and broad knowledge, whereas kenkyūsha focuses on the active process of research and discovery.

Respect for the Profession

In Japan, researchers are generally held in high regard for their dedication and contributions to knowledge and society. Using the term けんきゅうしゃ respectfully is important.

Create Your Own Sentences

The best way to learn is by doing. Try writing your own sentences using けんきゅうしゃ, describing hypothetical researchers or situations where a researcher might be involved.

Memorize It

Mnemonic

Imagine a 'Ken' doll doing 'kyu' (cue) cards for a 'sha' (show) about research. The Ken doll is the researcher.

Visual Association

Picture a person in a lab coat with a magnifying glass over a complex diagram, looking intently. The lab coat and magnifying glass represent research, and the person is the 'kenkyūsha'.

Word Web

Research Study Scientist Scholar Investigator Academic University Laboratory

Challenge

Try to explain what a けんきゅうしゃ does to someone who doesn't know the word, using only simple English and relating it to activities they understand, like solving puzzles or finding answers.

Word Origin

The word けんきゅうしゃ (kenkyūsha) is a compound word formed from two parts: 'kenkyū' (研究) meaning 'research' or 'study', and 'sha' (者) meaning 'person' or 'specialist'. This suffix 'sha' is commonly used to denote a professional or someone engaged in a particular activity, such as 'igakusha' (physician) or 'shokunin' (craftsman, though not using 'sha').

Original meaning: Literally 'research person' or 'study specialist'.

Sino-Japanese (Kanji-based)

Cultural Context

The term kenkyūsha is generally neutral and does not carry any negative connotations. It is a professional designation.

In English-speaking cultures, 'researcher' is also a respected profession, often associated with innovation and discovery. The emphasis on rigorous methodology and the pursuit of knowledge is similar.

Hideki Yukawa (湯川 秀樹), a Nobel laureate in Physics, was a prominent Japanese researcher. Shinya Yamanaka (山中 伸弥), a Nobel laureate in Medicine, is a leading researcher in regenerative medicine. The many researchers involved in developing Japan's advanced technologies (e.g., in robotics, automotive, electronics).

Frequently Asked Questions

10 questions

Both terms translate to 'researcher'. However, kenkyūsha is a more general term that can apply to anyone conducting research, including professors, independent scholars, and those in academic or scientific roles. Kenkyūin often implies someone employed as a researcher within a specific institution, such as a research institute or a company's R&D department. It can sometimes suggest a more defined job role. In many practical situations, they are used interchangeably, but kenkyūsha is broader.

Yes, absolutely. Kenkyūsha is not limited to scientific fields. It applies to anyone who conducts systematic research and investigation, including historians, linguists, sociologists, economists, literary critics, and many other scholars in the humanities and social sciences. The core meaning is about the methodology of research, not the specific subject matter.

Kenkyūsha is generally considered a neutral to formal term. It is appropriate for academic discussions, professional contexts, news reports, and formal writing. In very casual conversations, you might hear more informal descriptions, but kenkyūsha is the standard and respected term for a researcher.

Japanese nouns, including kenkyūsha, do not typically have a distinct plural form. Plurality is usually understood from the context or indicated by quantifiers like 'many' (多く - ōku) or specific numbers. If you need to emphasize plurality, you might add tachi (たち) or ra (ら) after kenkyūsha (e.g., 研究者たち - kenkyūsha-tachi), but this is less common in formal writing for this particular word.

You can use kenkyūsha as a subject (e.g., 研究者が発見した - A researcher discovered), as part of a descriptive phrase (e.g., 大学の研究者 - University researcher), or after the particle 'wa' or 'ga' to identify someone's role (e.g., 彼は研究者です - He is a researcher). Remember to use appropriate particles like の (no) to connect it with fields of study or affiliations.

A common mistake is using it for any student; kenkyūsha implies a professional researcher, not a general student (学生 - gakusei). Also, avoid overusing it in very casual conversation where a simpler term might be more natural. Ensure you understand that 'research' covers humanities and social sciences too, not just hard sciences.

The suffix 'sha' (者) means 'person' or 'specialist'. It's added to nouns to denote someone who engages in that activity or profession. For example, 'igakusha' (医師) means doctor, and 'senmonka' (専門家) means expert. So, kenkyūsha literally means 'research person'.

Yes, definitely. Professors at universities are typically involved in research and are often considered kenkyūsha. They might also be referred to as gakusha (scholar) or kyōju (professor), but their research activities clearly qualify them as kenkyūsha.

Kenkyūsha specifically refers to a researcher engaged in systematic, often academic or scientific, investigation. Tankyūsha means 'seeker' or 'explorer' and has a broader, often more philosophical or spiritual, connotation of searching for truth or knowledge, not necessarily within a formal research framework.

Researchers (kenkyūsha) work in virtually all fields of study, including medicine, physics, chemistry, biology, computer science, engineering, history, literature, sociology, psychology, economics, and many more. Any field that involves systematic inquiry and the pursuit of knowledge can have researchers.
