問診する

The Japanese verb 問診する (monshin suru) is a specialized medical term that translates to 'conducting a medical interview' or 'taking a patient history.' In the hierarchy of Japanese medical terminology, it represents the initial verbal phase of a clinical encounter where a healthcare professional—typically a doctor, nurse, or dentist—systematically asks a patient about their symptoms, medical history, lifestyle, and any allergies. Unlike a casual conversation about health, monshin is a structured diagnostic tool. It is the first step in the 'SOAP' (Subjective, Objective, Assessment, Plan) note-taking method used globally, representing the 'S' or Subjective data. In Japan, this process is highly standardized. When you enter a clinic, you are often handed a 問診票 (monshin-hyou), which is a medical questionnaire. The act of the doctor then reviewing this form and asking follow-up questions is the core of monshin suru.

Etymology and Nuance

The term is composed of two kanji: 問 (mon), meaning 'to question' or 'to inquire,' and 診 (shin), meaning 'to examine' or 'to diagnose.' Together, they literally mean 'to examine through questioning.' This distinguishes it from physical examination (触診 - shokushin) or visual inspection (視診 - shishin).

In contemporary Japan, the importance of monshin suru has grown with the shift toward patient-centered care. Historically, Japanese medicine was often paternalistic, with doctors making quick decisions based on physical signs. However, modern medical education emphasizes that up to 70-80% of a diagnosis can be derived from a thorough monshin alone. Therefore, when a professional says they will monshin suru, they are signaling a period of focused listening and analytical inquiry. It is not just about 'asking questions' (質問する - shitsumon suru); it is a professional action aimed at identifying a pathology. You will hear this word in hospitals (病院), clinics (診療所), and even in veterinary contexts when a vet asks a pet owner about the animal's behavior. It is also used in psychological settings, though 'intabyuu' or 'mensetsu' might sometimes be used depending on the school of thought.

The verb is a 'suru-verb' (noun + suru), making it versatile. It can be used in the passive form monshin sareru when speaking from the patient's perspective in a formal context, though 'monshin wo ukeru' is more common. It is also frequently found in compound nouns like 問診技術 (monshin gijutsu), referring to the interviewing skills of a medical student or professional. In the context of the Japanese National Medical Licensing Examination, monshin is a critical subject, highlighting its technical weight. If you are learning Japanese for professional reasons, especially in healthcare, mastering this word is essential for describing the diagnostic process accurately and professionally.

Contextual Usage

It is rarely used outside of medical or health-related contexts. Using it in a police investigation or a job interview would be considered a category error and might sound humorous or overly clinical.

Using 問診する (monshin suru) correctly requires an understanding of the relationship between the healthcare provider and the patient. Because it is a formal, technical term, it is typically used in the third person (describing what a doctor does) or in professional reports. When a doctor speaks to a patient, they might not use the word monshin directly, but rather say 'O-hanashi wo ukagaimasu' (I will hear your story/details). However, in the medical records (karte) or when discussing a case with colleagues, monshin suru is the standard term. The grammatical structure is straightforward: [Subject: Doctor] ga [Object: Patient] ni/wo [monshin suru]. The particle 'ni' is often used to indicate the target of the inquiry, while 'wo' can be used if the interview itself is the object of the action (e.g., 'monshin wo okonau').

Formal Applications

In formal writing, you will see it as: 'Kanja no kigen wo monshin suru' (To interview the patient about their origins/start of symptoms). It is also used in the potential form 'monshin dekiru' to describe a doctor's ability to extract information.

One important aspect of using this verb is the adverbial support it often receives. Words like teinei ni (carefully/politely), shousai ni (in detail), or tekitotsu ni (appropriately) frequently precede monshin suru. This emphasizes the quality of the diagnostic inquiry. Furthermore, in the context of Japanese medical culture, monshin suru implies a certain level of Keigo (honorific language) being used by the doctor toward the patient, even if the verb itself is in a neutral form in a textbook. If you are describing a scene in a medical drama, you might say, 'Sensei ga yasashiku monshin shite kureta' (The doctor kindly interviewed me/them). This uses the '-te kureru' auxiliary to show gratitude for the doctor's care.

For students of Japanese, it is useful to practice the different tenses. 'Monshin shimashita' (conducted the interview), 'monshin shite imasu' (is conducting the interview), and 'monshin shinai' (does not interview). In some cases, hospitals might automate parts of the process. You might see a sentence like: 'AI ga kanja wo monshin suru shisutemu' (A system where AI conducts the medical interview). This reflects the modern technological integration in Japanese healthcare. When using the noun form monshin alone, it often pairs with the verb okonau (to perform/conduct) for a more formal, academic tone: 'Monshin wo okonau' instead of 'monshin suru'.

Common Collocations

'Shoka (first visit) monshin suru', 'Sairai (follow-up) monshin suru', and 'Denwa (telephone) monshin suru' are common variations in clinical settings.

You will encounter 問診する (monshin suru) in several specific domains in Japan. The most obvious is within the walls of a healthcare facility. If you are waiting in a Japanese hospital, you might hear a nurse say over the intercom, 'Tsugi ni monshin wo okonaimasu node, dai-ni shinsatsushitsu e o-koshi kudasai' (We will now conduct the medical interview, so please come to Consultation Room 2). Here, the noun form is used, but the underlying action is monshin suru. It is also a staple of medical education. During 'OSCE' (Objective Structured Clinical Examination) in Japanese medical schools, students are graded on their ability to monshin suru effectively, focusing on their communication style and clinical reasoning.

Media and Entertainment

In Japanese medical dramas (iryou dorama) like 'Doctor-X' or 'Code Blue,' the term is used frequently during diagnostic scenes. Characters will discuss the results of their 'monshin' to narrow down a difficult diagnosis.

Another common place to see this word is on medical forms and health insurance documents. When you apply for a new insurance policy or undergo a yearly health check-up (kenkou shindan), you will encounter the 'monshin' section. In these contexts, it refers to the self-reported section where you answer questions about your smoking habits, alcohol consumption, and family history. While you are technically 'answering' (kaitou suru), the section itself is titled 'monshin' because it is the written equivalent of the verbal interview. Furthermore, in the pharmaceutical industry, pharmacists monshin suru when they ask if you have had any side effects from previous medications before dispensing a new prescription.

In the digital age, 'Online Monshin' is becoming a buzzword in Japan. With the rise of telemedicine, many clinics use apps where patients monshin suru (interact with a chat-bot or fill a digital form) before their video consultation. This saves time and ensures the doctor has all the necessary data. You might see advertisements for these services saying, 'Sumaho de kantan ni monshin dekiru' (You can easily do the medical interview on your smartphone). This usage blurs the line between the doctor doing the action and the patient providing the data, but the term monshin remains the anchor for the entire data-gathering process. In academic journals and medical research papers, the effectiveness of different monshin techniques is a common topic of study, often focusing on how to improve patient satisfaction and diagnostic accuracy.

Public Service Announcements

During the COVID-19 pandemic, the term was used in public health announcements regarding the screening process before vaccination. 'Sesshu mae ni ishi ga monshin shimasu' (A doctor will interview you before the vaccination).

The most frequent mistake learners make with 問診する (monshin suru) is using it in non-medical contexts. Because 'medical interview' is often translated as just 'interview' in some dictionaries, students might try to use it for a job interview or a media interview. However, monshin is strictly clinical. For a job interview, use 面接する (mensetsu suru). For a media or research interview, use インタビューする (intabyuu suru). For a police interrogation, use 取り調べ (torishirabe). Using monshin in these cases would sound like you are trying to diagnose the interviewer or the suspect with a disease, which would be very confusing.

Confusing with Physical Exams

Another common error is confusing 'monshin' with 'shinsatsu' (medical examination). While 'shinsatsu' is the umbrella term for the whole visit, 'monshin' is specifically the talking part. You shouldn't say 'monshin suru' if you are actually using a stethoscope; that would be 'choushin suru' (to auscultate).

Grammatically, a mistake often occurs with the particles. Some learners use 'monshin wo suru' correctly, but forget that when using it as a transitive verb with 'suru', the patient is often marked with 'wo' (the direct object) or 'ni' (the target). However, 'ni' is more common when emphasizing the interaction. Another nuance is the direction of the action. A patient cannot 'monshin suru' a doctor. If a patient says 'I will monshin the doctor,' it sounds like they are role-playing as the physician. Patients should say 'monshin wo ukeru' (receive) or 'monshin ni kotaeru' (answer the interview). Misusing the direction of this verb is a common CEFR B1 level error.

Finally, there is the confusion between monshin and mensetsu in psychiatric settings. While monshin is used for physical ailments, psychiatric evaluations often use 精神科面接 (seishinka mensetsu). Using monshin for a deep psychological therapy session might feel a bit too 'biological' or cold. It implies a checklist-style inquiry rather than a therapeutic dialogue. Understanding these subtle boundaries helps in achieving a C1/C2 level of natural Japanese. Avoid using monshin for casual health check-ins between friends, like 'How are you feeling?'. In that case, just use 'Choushi wa dou?' or 'Guai wa dou?'. Monshin is too heavy and professional for a friendly chat.

Spelling and Kanji Mistakes

Do not confuse 問 (ask) with 間 (between/interval). While they look similar, 'manshin' (inter-examination?) is not a word. Also, ensure the 'shin' is 診 (examine) and not 震 (shake) or 臣 (retainer).

To truly master 問診する (monshin suru), one must understand how it relates to other medical and inquiry-related verbs. The Japanese language has a rich vocabulary for different types of 'looking' and 'asking,' especially in professional fields. The most common synonym is 診察する (shinsatsu suru), which means 'to examine a patient.' However, shinsatsu is a broader term that includes monshin, physical tests, and looking at the patient's throat or eyes. If monshin is the 'interview,' shinsatsu is the 'entire consultation.'

Comparison Table

• 問診 (Monshin): Focus on verbal history and symptoms.
• 診察 (Shinsatsu): The general act of medical examination.
• 診断 (Shindan): The final diagnosis or conclusion.
• 検診 (Kenshin): A health screening or check-up for healthy people.

Another related word is カウンセリング (kaunseringu). While monshin is diagnostic and seeks to find a disease, kaunseringu is often therapeutic and seeks to provide support or mental health treatment. In a clinical setting, a doctor might start with monshin and then move into kaunseringu if the patient's issues are psychological. There is also 聴取する (choushu suru), which means 'to hear out' or 'to take a statement.' This is used more in legal or official contexts (like 'jijou choushu' - police questioning of a witness). While it involves asking questions, it lacks the 'medical examination' (診) nuance of monshin.

In terms of more specific medical inquiries, you might encounter 現病歴 (genbyoureki), which refers to the history of the current illness, or 既往歴 (kioureki), which is the past medical history. A doctor will monshin suru specifically to find out these details. If the inquiry is about lifestyle (diet, exercise), the term 生活習慣の聞き取り (seikatsu shuukan no kikitori) might be used in a public health context. Kikitori is a softer, more general word for 'gathering information by hearing.' Using monshin suggests a more rigorous, scientific approach than kikitori. In modern Japanese medical discourse, the term 医療面接 (iryou mensetsu) is often used in textbooks as a synonym for monshin, emphasizing the 'interview' (mensetsu) aspect and the communication skills required.

Register Differences

'Monshin' is the technical term. 'O-hanashi' is the patient-friendly term. 'Iryou mensetsu' is the academic/educational term. 'Kikitori' is the administrative term.
