설명 開催する in your Level:

At the A1 level, learners usually focus on very basic verbs like 'suru' (to do) or 'shimasu.' While 'kaisai suru' might be too advanced for daily conversation at this stage, you will see it on posters for events. Think of it as a special word for 'big parties' or 'festivals.' You don't need to use it yourself yet, but when you see the kanji for 'open' (開) and 'event' (催) together, just remember it means something is happening there. It is like the 'grand opening' sign on a store. At this level, just focus on recognizing the word in the context of 'event' + 'kaisai.'

At the A2 level, you start to learn more specific verbs. You might still use 'paatii o shimasu' (I will do a party), but you can begin to recognize 'kaisai suru' in announcements. You will notice it used with words like 'matsuri' (festival) or 'shiai' (match/game). You should understand that this word is more formal than 'shimasu.' If you are writing a simple announcement for a club activity, using 'kaisai shimasu' makes it sound more official. You should also start to recognize the past tense 'kaisai shita' (was held) in simple news stories or blog posts about events.

At the B1 level (the target level for this word), you are expected to use 'kaisai suru' correctly in formal or semi-formal contexts. You should be able to distinguish between 'hiraku' (casual/semi-formal) and 'kaisai suru' (formal). You will use this word to talk about business meetings, seminars, and exhibitions. You should also be comfortable with the passive form 'kaisai sareru' because it is the standard way to describe events in reports. You can now use the particle 'de' correctly for the venue and understand how to talk about the 'kaisai-chi' (venue) and 'kaisai-bi' (date) of an event.

At the B2 level, you should be able to use 'kaisai suru' fluently in business settings and academic writing. You will understand nuanced variations like 'shusai' (hosting), 'kyousai' (co-hosting), and 'kouen' (sponsorship). You should be able to discuss the logistical aspects of 'kaisai,' such as 'kaisai no hiyou' (costs of holding the event) or 'kaisai ni itaru made no keisai' (the process leading up to the holding of the event). You are also expected to use honorifics correctly with this verb, such as 'kaisai itashimasu' (humble) or 'go-kaisai' (honorific noun form) when appropriate.

At the C1 level, 'kaisai suru' is a basic building block for complex discussions. You will use it to analyze the socio-economic impacts of holding mega-events like the World Cup or World Expos. You should be able to use it in sophisticated structures like '...o kaisai suru ni atatte' (upon holding...) or '...no kaisai o miokuru' (to decide against holding...). Your vocabulary should include related formal terms like 'kyokou' (solemnizing) or 'shikko' (execution). You can read and understand legal documents or high-level policy papers that discuss the regulations for holding large-scale public gatherings.

At the C2 level, you have complete mastery over the word and its various registers. You can use it in high-level diplomacy, legal discourse, and literary analysis. You understand the historical evolution of the word and can use it to discuss the philosophy of public gatherings. You are capable of drafting official charters for international organizations regarding how events should be 'kaisai' (held) under specific standards. You can also use the word metaphorically or in highly specialized contexts, such as the 'kaisai' of a specific legal hearing or a unique historical assembly, with perfect native-level nuance.

Formal verb for holding/hosting events.
Used for festivals, meetings, and sports.
Requires 'de' for location and 'ga' for the event.
Common in news and business contexts.

The Japanese verb 開催する (kaisai suru) is a formal and highly essential term used to describe the act of holding, hosting, or organizing an event. At its core, it combines the kanji 開 (kai), meaning to open or start, with 催 (sai), which refers to holding an event or urging something to happen. Unlike the simpler verb yaru (to do) or okonau (to carry out), kaisai suru carries a weight of officiality and scale. It is the standard term you will encounter in news broadcasts, business emails, and official announcements regarding everything from the Olympic Games to a local neighborhood meeting. When you use this word, you are signaling that the event is planned, structured, and has a specific purpose or venue. It is not used for spontaneous gatherings or casual hangouts with friends; rather, it implies a level of preparation and formal hosting.

Formal Context: Used for international conferences, sports tournaments, and corporate exhibitions where a clear organizer is present.
Scale of Event: Typically refers to events that take place at a specific physical or virtual venue with an invited or public audience.

来月、東京で国際会議が開催される予定です。 (An international conference is scheduled to be held in Tokyo next month.)

In a professional environment, mastering kaisai suru is vital. If you are the one organizing a webinar, you would say you are 'holding' it using this verb. It creates a sense of professional distance and respect for the event's structure. Furthermore, the noun form, 開催 (kaisai), is frequently used in compound words like kaisai-bi (the date of the event) or kaisai-chi (the venue/location of the event). Understanding this word allows a learner to navigate Japanese public spaces more effectively, as signs and posters for festivals (matsuri) or concerts will almost always feature this kanji pair prominently. It bridges the gap between basic Japanese and the language used in the public sphere.

One nuance that English speakers should note is that kaisai suru focuses on the 'opening' and 'hosting' aspect. If you want to say an event 'took place' in a more general sense, you might use okonawareta (was carried out), but kaisai emphasizes the act of the organizer bringing the event to life. In the context of the COVID-19 pandemic, Japanese news frequently used the phrase kaisai enki (postponement of the event) or kaisai chuushi (cancellation of the event), highlighting how central this word is to the logistics of public life. Whether it is a small workshop or a global summit, kaisai suru is the go-to verb for the formal realization of a planned gathering.

Using 開催する (kaisai suru) requires an understanding of its transitivity and formal structure. As a suru-verb, it can function as both an active verb (to hold an event) and a passive verb (an event is held). In the active voice, the subject is the organizer. For example, 'The company holds a seminar' becomes 'Kaisha ga seminaa o kaisai suru.' However, in many contexts, especially news and announcements, the passive form 開催される (kaisai sareru) is more common because the focus is on the event itself rather than the specific individuals organizing it.

Active Usage: [Organizer] が [Event] を開催する。 (The [Organizer] holds [Event].)
Passive Usage: [Event] が [Location] で開催される。 (The [Event] is held at [Location].)

この展示会は毎年10月に開催されます。 (This exhibition is held every October.)

When discussing the location, use the particle で (de). For example, 'Online de kaisai suru' (to hold online). This is a modern and very frequent usage. If you are talking about the purpose or theme of the event, you might use the phrase ...o mokuteki to shite kaisai suru (to hold with the objective of...). This level of complexity is common in CEFR B1 and B2 Japanese levels. It's also important to note that kaisai can be used in the potential form kaisai dekiru (can hold/can be held) to discuss feasibility, which was a major topic during the discussions about the Tokyo Olympics.

Furthermore, in business settings, you might hear the humble or honorific versions. While kaisai itashimasu is a standard humble form used by organizers when speaking to clients, kaisai saremasu serves as the respectful honorific when talking about an event hosted by a superior or a respected organization. This versatility makes it an indispensable tool for anyone working in a Japanese corporate or academic environment. By varying the tense and politeness level, you can adapt kaisai suru to almost any formal scenario involving the gathering of people for a specific cause.

You will encounter 開催する (kaisai suru) in several key areas of Japanese life. First and foremost is the world of **mass media**. News anchors regularly use it when reporting on government summits, sports events like the Koshien baseball tournament, or international festivals. If you watch NHK News, you will hear the phrase 'Kaisai sareru hoko de chosei shite imasu' (Adjustments are being made toward holding the event) quite often when plans are being finalized. It is the vocabulary of 'official news.'

Public Announcements: Train stations and public bulletin boards often have posters saying 'XX Matsuri Kaisai!' (XX Festival is being held!).
Corporate Culture: In office meetings, a manager might say, 'Rainen no kabunushi sokai wa doko de kaisai shimasu ka?' (Where will we hold next year's shareholders' meeting?).

パリオリンピックの開催まであとわずかです。 (There is only a little time left until the holding of the Paris Olympics.)

Another common place to see this word is in **digital spaces**. On Japanese event platforms like Peatix or Doorkeeper, the button for 'Host an Event' often uses the word kaisai. Similarly, in the world of **gaming**, limited-time events are frequently announced as 'Gentei ibento kaisai chuu!' (Limited event currently being held!). This shows that while the word is formal, its usage has expanded into modern subcultures and digital interactions where an 'event' (ibento) is a central concept.

Finally, the **academic world** relies heavily on this term. University lectures, symposiums, and entrance ceremony details are always communicated using kaisai. If you are a student in Japan, your syllabus or campus emails will use this verb to tell you when and where your orientation or special seminars will take place. It is a word that defines the schedule of public and professional life, marking the difference between a random occurrence and a planned, meaningful gathering.

One of the most frequent mistakes English speakers make with 開催する (kaisai suru) is overusing it for casual situations. Because 'to hold' in English can be used for things like 'holding a small dinner with friends' or 'holding a secret,' learners often try to translate these literally. In Japanese, kaisai suru is too heavy for a casual party. For a small gathering of friends, you should use hiraku (to open/hold) or simply yaru (to do). Using kaisai suru for a three-person pizza party would sound unintentionally hilarious, as if you were treating the pizza party like a formal diplomatic summit.

Mistake: Casual Parties: Incorrect: Tomodachi to paatii o kaisai shita. (I held a party with friends - sounds too formal.)
Correct: Tomodachi to paatii o hiraita / yatta.
Mistake: Physical Holding: Incorrect: Nimotsu o kaisai suru. (Holding luggage - impossible usage.)
Correct: Nimotsu o motsu.

× 友達と誕生日会を開催した。
○ 友達と誕生日会を開いた。

Another mistake involves the particle usage. Some learners use the particle ni (に) for the location of the event, thinking of it as 'existing' at a location. However, because kaisai suru is an action, the particle de (で) is mandatory for the location where the action occurs. Saying 'Tokyo ni kaisai suru' is grammatically incorrect; it must be 'Tokyo de kaisai suru.' Additionally, confusing kaisai with shusai (sponsoring/organizing) is common. While kaisai is the act of holding the event, shusai specifically refers to the person or body who is the main sponsor or host.

Lastly, learners sometimes forget to use the passive voice when the event is the subject of the sentence in a formal report. In English, we often say 'The event takes place on Monday.' In Japanese, saying 'Event ga kaisai suru' sounds like the event itself is an entity performing an action. To sound natural, use 'Event ga kaisai sareru' (The event is held). This subtle shift in voice is what separates an intermediate learner from a truly proficient speaker. Pay attention to how the subject and verb interact to avoid sounding like a translation bot.

Japanese has several words that overlap with 開催する (kaisai suru), and choosing the right one depends on the formality and nature of the event. The most common alternative is 行う (okonau). While kaisai suru is specifically for 'holding events,' okonau is a general verb for 'to carry out' or 'to conduct.' You can okonau a test, a survey, or an experiment, but you wouldn't usually kaisai them unless they were large, public-facing events.

開く (hiraku): Meaning: To open/hold. Used for both formal and informal gatherings. It feels slightly more personal than 'kaisai suru.' Good for parties and small workshops.
催す (moyoosu): Meaning: To hold/host. This is a more literary or traditional way to say you are hosting a gathering, often used for banquets or tea ceremonies.
実施する (jisshi suru): Meaning: To implement/enforce. Used for policies, exams, or planned operations. It emphasizes the execution of a plan rather than the gathering of people.

Comparison:
1. 運動会を開催する (Hold a sports day - formal event)
2. 飲み会を開く (Hold a drinking party - casual gathering)

Another related term is 主催する (shusai suru). As mentioned before, this means 'to sponsor' or 'to be the primary host.' If you are the person in charge of the event, you are the shusaisha. You might say, 'ABC Foundation ga kaisai suru' (The ABC Foundation holds the event), but you could also say 'ABC Foundation ga shusai suru' to emphasize their role as the organizer. Additionally, 共催 (kyousai) means 'co-hosting' when two or more organizations work together. Understanding these distinctions helps you navigate the complex social hierarchies of Japanese event planning.

Finally, consider 挙行する (kyokou suru). This is an extremely formal word used almost exclusively for solemn ceremonies like weddings, funerals, or graduation ceremonies. While kaisai is about 'holding' an event for people to participate in, kyokou is about 'performing' a rite or ceremony. Choosing kaisai for a graduation ceremony is okay, but kyokou adds a layer of dignity and tradition. By learning these alternatives, you can tailor your Japanese to perfectly match the atmosphere of whatever you are discussing.
