外出

The Japanese word 外出 (がいしゅつ - gaishutsu) is a fundamental noun that translates most directly to "going out" or "leaving one's home or office." While English speakers might use a variety of phrases like "stepping out," "running errands," or "heading out," the Japanese language often consolidates these actions into this specific Sino-Japanese (Kango) compound. It is composed of two primary kanji: 外 (soto - outside) and 出 (deru - to exit). Together, they create a formal yet versatile term used in daily conversation, business settings, and official announcements. Understanding when to use gaishutsu versus its more casual counterpart dekakeru is a key milestone for B1-level learners.

Formal Contexts

In a professional environment, you will frequently see this word on status boards. If a colleague is away from their desk for a meeting or a quick break, their status might be marked as 外出中 (gaishutsu-chū), meaning "currently out."

Official Warnings

During natural disasters or public health crises, the government issues 外出自粛 (gaishutsu jishuku) requests, which ask citizens to refrain from going out unnecessarily. This highlights the word's role in serious, official communication.

One of the most important nuances of gaishutsu is that it implies a return. Unlike "moving out" or "leaving forever," gaishutsu suggests a temporary absence from a home base. It is a neutral term that doesn't specify the purpose of the trip—whether you are buying groceries, meeting a friend, or attending a business meeting, the act of physically crossing the threshold of your building is covered by this word. In the post-2020 era, the term gained even more prominence due to social distancing measures, making it a staple of modern Japanese vocabulary.

Grammatical Function

As a suru-verb, it becomes 外出する (gaishutsu suru). This is the standard way to express the action of leaving the house in a slightly more formal or objective tone than the common verb dekakeru.

Finally, the word is often paired with time-specific nouns. You might hear ya-gaishutsu (going out at night) or shū-gaishutsu (going out for the weekend). It serves as a building block for many compound words that describe the frequency and nature of our movements in society. For a B1 learner, mastering gaishutsu allows you to navigate professional emails and news reports with much greater ease.

Using 外出 (gaishutsu) correctly requires an understanding of Japanese sentence structure and the specific particles that accompany it. Since it functions as both a noun and a suru-verb, its flexibility is its greatest strength. However, this flexibility can sometimes lead to confusion for English speakers who are used to more specific verbs. Below, we explore the various ways this word integrates into natural Japanese speech.

As a Noun with Particles

When used as a noun, it often takes the particle no to modify other nouns, or o when being restricted or encouraged. For example, gaishutsu no junbi (preparations for going out) or gaishutsu o hikaeru (to refrain from going out).

When transforming it into a verb, gaishutsu suru is used to describe the act itself. Note that unlike dekakeru, which is often followed by a destination (e.g., gakkō ni dekakeru), gaishutsu is more focused on the act of leaving the current location. While you can say kaimono ni gaishutsu suru (go out for shopping), it sounds more formal and objective than kaimono ni dekakeru.

Expressing Duration and State

The suffix -chū is frequently added to indicate a state of being out. Gaishutsu-chū ni kaji ga atta (A fire broke out while I was out). This is a very common pattern in news reporting and storytelling.

Another common structure involves the word gaishutsu-gi, which refers to "going-out clothes" (as opposed to loungewear or pajamas). This demonstrates how gaishutsu acts as a categorizing noun for activities and items related to the world outside the home. In B1 level conversations, being able to talk about what you wear or what you do while gaishutsu-ing adds a layer of natural fluency.

Negative and Prohibitive Forms

The word is often used with kinshi (prohibition). Gaishutsu kinshi (Stay-at-home order/Curfew). This is essential for understanding safety protocols in Japan.

To truly master 外出 (gaishutsu), one must look beyond the textbook and into the actual environments where the word thrives. Unlike slang terms that fluctuate with pop culture, gaishutsu is a stable, high-frequency word found in professional, civic, and domestic life. If you spend a day in Tokyo, you are likely to encounter this word multiple times in various formats.

The Modern Office

In Japanese offices, communication is often indirect. A whiteboard or a digital status app like Slack or Cybozu will use 外出 to tell colleagues that someone is not at their desk. It is the polite way to say "I'm working, but I'm not here."

Public Transportation and Safety

During extreme weather like typhoons or heavy snow, station announcements and news tickers will display 不要不急の外出 (fuyō fukyū no gaishutsu). This means "non-essential and non-urgent outings," advising people to stay indoors.

In television dramas and movies, you'll hear gaishutsu used when characters are discussing their movements or providing alibis to detectives. It has a slightly clinical or objective feel compared to the warmth of dekakeru. If a parent is telling a child to be careful when they go out, they might use dekakeru, but if a doctor is asking a patient about their activity levels, they will almost certainly use gaishutsu.

Retail and Service Industry

When staying at a traditional Japanese inn (Ryokan) or a business hotel, the staff might ask about your 外出の予定 (plans for going out) so they know when to clean your room or prepare dinner. It is the standard term used in hospitality to respect the guest's autonomy while managing operations.

In summary, gaishutsu is the "utility player" of Japanese movement vocabulary. It appears in the most serious of government warnings and the most mundane of office interactions. For a learner, hearing this word should trigger a mental image of a door opening and a person stepping out into the public sphere with a specific intention, however small.

While 外出 (gaishutsu) is a relatively straightforward word, English speakers often stumble over its nuance and grammatical collocation. Because English uses "go out" for everything from a romantic date to taking out the trash, the specific boundaries of gaishutsu can be tricky. Understanding these pitfalls will help you sound more like a native speaker and less like a translation software.

The "Dating" Confusion

In English, "We are going out" can mean "We are in a romantic relationship." In Japanese, gaishutsu never carries this romantic meaning. Using gaishutsu suru to describe a relationship would sound very strange. Instead, use tsukiau (to date/associate) or dēto suru.

Redundancy with "Iku"

Learners often try to say gaishutsu ni iku (to go to going out). This is redundant. Since gaishutsu already contains the concept of movement, you should simply say gaishutsu suru or gaishutsu ni deru.

Another common error is using gaishutsu when the action of leaving is permanent or long-term. For example, if you are leaving your job for the day and going home, the correct term is taisha (leaving the office) or kitaku (returning home). Using gaishutsu in this context might lead your boss to believe you are coming back later that afternoon.

Confusing with "Soto ni deru"

Soto ni deru is a literal physical description (to step outside). Gaishutsu is a social/functional description. If you step onto your balcony to check the weather, you are soto ni deru-ing, but you are not gaishutsu-ing.

Lastly, be careful with the particle ni. While gaishutsu ni deru is acceptable, gaishutsu o suru is more common when emphasizing the noun. Many students forget that gaishutsu is a noun first and a verb second, leading to awkward phrasing when trying to use it as a standalone action without the suru support.

Japanese is a language of fine distinctions, and the concept of "leaving" is no exception. To use 外出 (gaishutsu) like a pro, you must know its neighbors in the dictionary. Each of these words covers a specific slice of the "going out" experience, and choosing the right one displays your sensitivity to context and register.

外出 (Gaishutsu) vs. 出かける (Dekakeru)

Gaishutsu is a Sino-Japanese word, making it sound more formal, objective, and often business-oriented. Dekakeru is a native Japanese verb (Kun-yomi), sounding warmer, more personal, and casual. You dekakeru to a party; you gaishutsu for a client meeting.

外出 (Gaishutsu) vs. 離席 (Riseki)

Riseki literally means "leaving one's seat." This is used when you are still in the building (e.g., going to the restroom or getting coffee) but not at your desk. Gaishutsu means you have actually left the building.

Other related terms include shutsuryoku (output), which sounds similar but is used for data or power, and shussha (going to work/arriving at the office). If you are leaving the office to go home, use taisha. If you are leaving the office to go to another office, use gaishutsu.

Antonym: 帰宅 (Kitaku)

The most common opposite of gaishutsu is kitaku (returning home). In a typical day, you gaishutsu in the morning and kitaku in the evening. Another opposite is zai-taku (being at home/working from home).

Understanding these distinctions allows you to choose the word that fits the "social temperature" of the room. Using gaishutsu in a business report shows professionalism, while using dekakeru in a text to a friend shows intimacy. Mastering this spectrum is the hallmark of an advanced learner.
