家事

The Japanese word 家事 (kaji) is a fundamental noun that translates most directly to 'housework' or 'domestic chores' in English. It is composed of two kanji characters: 家 (ka/ie), meaning 'house' or 'home', and 事 (ji/koto), meaning 'matter', 'thing', or 'incident'. Together, they literally signify 'home matters' or 'things related to the household'. This word is used in daily conversation to describe the various repetitive tasks required to keep a living space clean, organized, and functional. It encompasses a wide range of activities including cooking (炊事 - suiji), cleaning (掃除 - souji), laundry (洗濯 - sentaku), and general household management. While it primarily refers to the physical labor of maintaining a home, it can also touch upon the administrative side of domestic life, such as budgeting or grocery shopping. In Japanese society, the concept of 家事 has evolved significantly over the decades. Traditionally, it was viewed through a gendered lens, but modern discourse often focuses on 家事分担 (kaji buntan), or the sharing of household chores between partners. Understanding this word is essential because it appears in everything from casual chats with friends to formal surveys about lifestyle and work-life balance. It is a 'neutral' word, neither overly formal nor slangy, making it appropriate for almost any context where domestic labor is discussed. In recent years, the phrase 名もなき家事 (namonaki kaji), or 'nameless housework', has gained popularity to describe the small, invisible tasks like replacing a toilet paper roll or emptying the lint trap that are often overlooked but essential for a smooth-running home.

Scope of Work

家事 covers everything from the moment you wake up and make the bed to the moment you turn off the lights at night, focusing on the maintenance of the physical environment and the well-being of the inhabitants.

When using 家事, it is almost always paired with the verb する (suru - to do). Unlike some English verbs like 'to clean' or 'to cook' which describe specific actions, 家事 is the umbrella term. You wouldn't usually say 'I'm 家事-ing' in the middle of a specific task; rather, you use it to describe the general block of time or responsibility. For example, 'I have a lot of housework to do today' (今日は家事がたくさんあります) is a very common expression. It is also used to distinguish domestic labor from professional labor (仕事 - shigoto). In a social context, if someone asks what you did over the weekend and you spent it cleaning and meal-prepping, you might reply with '家事に追われていました' (kaji ni owarete imashita), which means you were 'chased' or overwhelmed by housework. This nuance of being 'chased' by chores is a very common way to express that domestic duties took up all your free time.

Cultural Nuance

In Japanese culture, there is a strong emphasis on cleanliness and order, making 'kaji' a significant part of one's social standing and personal discipline.

Furthermore, the word is used in various compound nouns that are essential for daily life. 家事代行 (kaji daikou) refers to housekeeping services where a professional comes to your home to perform chores. 家事手伝い (kaji tetsudai) is a term that was historically used to describe a young woman who stayed at home to help with chores before marriage, though this usage is becoming outdated. In modern media, you will often see 'kaji' in the context of 'life hacks' or 'kaji-tech' (housework technology), focusing on how to make these repetitive tasks more efficient. The emotional weight of 家事 can vary; for some, it is a therapeutic routine, while for others, it is a never-ending cycle of labor. In literature and film, the way a character handles 家事 is often used to demonstrate their mental state or their relationship with their family members.

Grammatical Pairing

The particle 'を' (wo) is most commonly used with 家事 to indicate the object of the action 'suru' (to do).

Using 家事 (kaji) correctly in a sentence involves understanding its role as a collective noun. While you can use specific words for 'washing dishes' or 'vacuuming,' using 家事 allows you to discuss the entirety of domestic responsibility. The most basic pattern is [Subject] は 家事 を します ([Subject] does housework). To make your Japanese sound more natural, you should learn the common verbs and adjectives that frequently accompany this word. For instance, to say someone is good at housework, you use 得意 (tokui) or 上手 (jouzu). Conversely, if someone dislikes it, you might use 苦手 (nigate) or 嫌い (kirai). In a sentence: '私は家事が苦手です' (I am not good at housework). This is a common self-deprecating remark in social settings. When discussing the volume of work, use 多い (ooi - many/much) or 忙しい (isogashii - busy). For example, '家事が多くて大変です' (There is so much housework it's difficult).

Verb Pairing: 済ませる (sumaseru)

This verb means 'to finish' or 'to get something out of the way'. Use it when you want to emphasize completing your chores early to enjoy free time.

Another important grammatical structure involves the particle に (ni) when used with verbs like 追われる (owareru - to be chased) or 専念する (sennen suru - to devote oneself to). These phrases describe the relationship the person has with their chores. '家事に追われる' implies a sense of being overwhelmed or lacking time for anything else, a very common sentiment among parents and busy professionals. On the other hand, '家事に専念する' might be used to describe someone who has decided to become a full-time homemaker. Additionally, the word 分担 (buntan) is crucial in modern contexts. It means 'division' or 'sharing'. You will often hear '家事の分担' (sharing of housework) in discussions about equality in the home. '夫と家事を分担しています' (I share the housework with my husband) is a sentence you'll find in many textbooks and real-life conversations about family dynamics.

In more formal or written contexts, such as an essay or a news report, you might see 家事労働 (kaji roudou), which means 'domestic labor'. This treats housework as a serious economic or social activity. For example, '家事労働の価値を再評価する' (Re-evaluating the value of domestic labor). When talking about children helping out, the phrase 家事の手伝い (kaji no tetsudai) is used. '子供に家事の手伝いをさせる' (Making children help with the housework) is a common topic in parenting discussions. The versatility of 家事 allows it to fit into complex grammatical structures, such as using ながら (nagara - while). '音楽を聴きながら家事をする' (Doing housework while listening to music) is a sentence that many learners can relate to. By mastering these patterns, you can discuss your daily routine with nuance and accuracy.

Verb Pairing: 協力する (kyouryoku suru)

Meaning 'to cooperate'. Used when family members work together on chores. '家族で家事に協力する' (The family cooperates on housework).

Adjective Pairing: 面倒な (mendou na)

Meaning 'troublesome' or 'bothersome'. '面倒な家事' is a very common way to describe chores you don't want to do.

The word 家事 (kaji) is ubiquitous in Japanese life, and you will encounter it in various media and real-life situations. One of the most common places to hear it is in lifestyle television programs or 'Wide Shows'. These programs often feature segments on 'kaji-tech' (housework techniques), showing viewers how to remove stubborn stains or how to cook a meal in under ten minutes. The hosts will frequently use the term when interviewing experts or 'charismatic housewives' (karisuma shufu) who have mastered efficient domestic management. If you watch Japanese morning TV, you'll likely hear it several times an hour. In these contexts, the word is often associated with self-improvement and efficiency, reflecting a cultural value placed on a well-ordered home. You will also see it prominently in commercials for cleaning products, laundry detergents, and kitchen appliances. The narration might say something like '家事をもっと楽しく' (Make housework more fun) or '家事の時間を短縮' (Shorten housework time).

In the Workplace

In Japanese offices, 'kaji' is a frequent topic of small talk during lunch breaks. Colleagues might complain about the 'kaji' they have to do when they get home, or discuss how they share chores with their partners.

In the realm of Anime and Manga, 家事 is a recurring theme, especially in the 'slice of life' genre. Characters who are particularly good at housework are often portrayed as reliable, maternal, or domestic. For example, in many series, a character's ability to handle 家事 is seen as a desirable trait. Conversely, a character who is terrible at housework (a 'kaji-onchi') is a common comedic trope. You might hear a character say, '私は家事が全くできません！' (I can't do housework at all!) as a point of embarrassment or humor. The word also appears in titles of shows, such as the famous drama and manga 'Kaseifu no Mita' (Mita the Housekeeper), though the term 家政 (kasei - household management) is used there, which is a more formal relative of 家事. In social media, hashtags like #家事 (kaji), #家事貯金 (kaji chokin - 'housework savings', meaning doing chores in advance), and #ズボラ家事 (zubora kaji - 'lazy housework' or shortcuts) are very popular among Japanese users sharing tips and photos of their homes.

Another place you will hear this word is in government announcements or news reports regarding gender equality and labor statistics. The term 無償労働 (mushou roudou - unpaid labor) is often used alongside 家事 to describe the economic value of what stay-at-home parents do. News anchors might report on the 'gender gap in 家事 hours' between men and women in Japan. In these serious contexts, the word carries a weight of social responsibility and systemic change. Finally, in educational settings, Japanese students have a subject called 家庭科 (kateika - home economics), where they learn the basics of 家事, such as sewing and cooking. Teachers will use the word when explaining the importance of being able to take care of oneself. Thus, from the playful banter of a comedy show to the serious tone of a news broadcast, 家事 is a word that reflects the daily reality of everyone living in Japan.

In Literature

Authors often use the description of a character's 'kaji' routine to ground the story in reality and show the passage of time or the character's discipline.

Service Industry

If you walk past a flyer for a cleaning service, it will almost certainly say '家事代行' (housework agency).

For English speakers learning Japanese, the word 家事 (kaji) presents a few pitfalls, primarily related to pronunciation and scope. The most significant mistake is the homophone confusion with 火事 (kaji), which means 'a fire' (as in a building on fire). While they sound identical to the untrained ear, the pitch accent and context are different. In 家事 (housework), the pitch is typically flat (Heiban), whereas in 火事 (fire), the accent often falls on the first syllable. If you tell someone, 'Yesterday, I did a big fire' (昨日、大きな火事をしました) instead of 'Yesterday, I did a lot of housework' (昨日、たくさん家事をしました), you will cause a lot of alarm! Always ensure the context of domesticity is established. Another common error is using 家事 to refer to office chores. In English, we might say 'I have some chores to do at the office,' but in Japanese, 家事 is strictly for the 'home' (家). For office tasks, you should use 雑用 (zatsuyou - miscellaneous tasks/chores) or 事務作業 (jimu sagyou - office work).

Confusing 家事 with 育児 (ikuji)

While they are related, 'kaji' is housework and 'ikuji' is childcare. Don't use 'kaji' when you specifically mean looking after children, although 'kaji' often encompasses the environment where children are raised.

A grammatical mistake learners often make is treating 家事 as a verb. In English, 'to housekeep' isn't common, but we say 'I am cleaning.' In Japanese, you cannot say '家事る' (kajiru). You must always use the support verb する (suru). Furthermore, learners sometimes confuse 家事 with 宿題 (shukudai - homework). Because 'housework' and 'homework' both contain the word 'home' and 'work' in English, it's easy to swap them. However, 宿題 is strictly for school assignments. Saying 'I have a lot of housework' when you mean school assignments will lead to confusion. Additionally, when describing someone's profession, don't say 'My job is 家事' unless you are a professional housekeeper (in which case you'd use 家事代行スタッフ). If you are a stay-at-home parent, the correct term is 主婦 (shufu - housewife) or 主夫 (shufu - househusband), and you would say you are engaged in 家事.

Finally, be careful with the particle usage. Some learners try to use に (ni) with 家事をする, but it should be を (wo). However, if you are 'good at' housework, you must use が (ga): '家事が得意です'. Another nuance is the difference between 家事 and 掃除 (souji). If you only cleaned the floor, say 掃除. If you cleaned the floor, did the dishes, and folded the laundry, then 家事 is the appropriate term. Using 家事 when you only did one specific task can sound slightly unnatural or overly broad. Lastly, avoid using 家事 when referring to professional building maintenance or janitorial work in a commercial setting; that is 清掃 (seisou). By keeping these distinctions in mind, you will avoid the most common errors and speak more like a native.

Professional vs. Personal

'Kaji' is personal. 'Seisou' is professional/commercial. 'Zatsuyou' is for office/admin chores.

Particle Pitfall

Remember: 家事を (object) する vs. 家事が (subject of state) 得意だ.

While 家事 (kaji) is the general term for housework, Japanese has several more specific words that you should know to enrich your vocabulary and sound more precise. Depending on the context—whether you're talking about cooking, cleaning, or the legal/economic aspects of a household—different words might be more appropriate. For example, if you want to focus specifically on the labor involved in preparing food, you would use 炊事 (suiji). This word specifically refers to cooking and the cleanup associated with it. While it's part of 家事, using 炊事 makes it clear that you aren't talking about laundry or dusting. Another important word is 家政 (kasei). This is a more formal and academic term for 'household management' or 'domestic science.' You see it in the term 家政婦 (kaseifu - housekeeper/maid) or in university departments like the 家政学部 (Faculty of Home Economics).

Comparison: 家事 vs. 掃除 (souji)

家事 (kaji) is the whole category (cooking, laundry, cleaning). 掃除 (souji) is specifically cleaning/vacuuming/dusting.

When discussing the 'chores' or 'errands' that don't necessarily happen inside the house, the word 雑用 (zatsuyou) is very useful. It translates to 'miscellaneous tasks' or 'odd jobs.' If you are running to the post office, the bank, and then picking up dry cleaning, you are doing 雑用 rather than 家事. In a family context, you might also hear 育児 (ikuji), which means 'child-rearing' or 'childcare.' While 家事 and 育児 are often grouped together in discussions about domestic life (often as 家事育児 - kaji ikuji), they are distinct categories of labor. For those who live in a more traditional or formal setting, 内職 (naishoku) might come up. This refers to 'side work' done at home, but it's usually piecework for pay, not chores. Knowing the difference between these ensures you don't accidentally say you're working for money when you're just doing the dishes.

Furthermore, in modern slang or trendy Japanese, you might see 家事シェア (kaji shea), which is a katakana version of 'housework share.' This is often used by younger couples to describe their collaborative approach to chores. Another related term is 時短家事 (jitan kaji), which refers to 'time-saving housework' techniques. This is a huge buzzword in Japan, where people are often very busy. You'll see it on the covers of magazines and in YouTube titles. If you are looking for a more poetic or old-fashioned way to describe domestic life, the word 暮らし (kurashi), meaning 'living' or 'daily life,' is often used. While it's not a direct synonym for chores, it encompasses the lifestyle that 家事 supports. For example, '丁寧な暮らし' (teinei na kurashi) means 'a careful, mindful lifestyle,' which usually involves doing housework with great care and attention to detail.

Comparison: 家事 vs. 炊事 (suiji)

家事 is the umbrella term. 炊事 is specifically about the kitchen and food preparation. You wouldn't use 炊事 for laundry.

Comparison: 家事 vs. 雑事 (zatsuji)

雑事 (zatsuji) is more formal than 雑用 (zatsuyou) and refers to miscellaneous affairs in general, not just household ones.
