掃除
そうじ
souji
= cleaning; sweeping
Souji (掃除) is the everyday Japanese word for cleaning a room or space by sweeping and tidying — and in Japan, it carries a cultural weight that goes far beyond household chores.
Souji refers specifically to the act of cleaning a physical space: sweeping floors, wiping surfaces, and removing dirt or clutter. It is used as a suru-verb, so souji suru means to clean or to do cleaning. The word applies to homes, classrooms, offices, and public spaces alike. In casual speech, people say souji shなければ (I have to clean) or souji shita (I cleaned), making it one of the most versatile action words at the N5 level. Unlike the English word clean, souji implies a deliberate, physical act of tidying rather than a general state of cleanliness.
Learners often confuse souji with sentaku (洗濯, laundry) or katazuke (片付け, tidying up). Souji focuses on sweeping and wiping surfaces, while katazuke is about putting things away and organizing. Note that the suru-verb form attaches directly: souji suru, souji shimasu, souji shite kudasai. A common error is treating it as an i-adjective or using it with ni naru — it does not work that way. Also remember: souji-ki (掃除機, literally cleaning machine) is the word for vacuum cleaner, so knowing souji immediately unlocks that compound.
掃除 combines two kanji with complementary meanings: 掃 (sou) means to sweep, depicting a hand holding a broom, and 除 (jo) means to remove or eliminate. Together they paint a precise picture — sweep and remove — which is exactly what souji entails. This transparent construction makes 掃除 one of the easier compound nouns for kanji learners to decode without memorization.

Formal / Cultural context
生徒たちは放課後に教室の掃除をする責任があります。
Seito-tachi wa hōkago ni kyōshitsu no souji wo suru sekinin ga arimasu.
Students are responsible for cleaning their classroom after school.
One of the first things foreign visitors notice about Japanese schools is that students clean their own classrooms, hallways, and even toilets. This daily ritual, called souji no jikan (掃除の時間, cleaning time), is built into the school schedule and is treated as part of education rather than maintenance work. The underlying idea is that caring for a shared space builds responsibility, humility, and community — values deeply embedded in Japanese school culture.
At the end of each year, Japanese households undertake ōsouji (大掃除, big cleaning), a tradition rooted in the older custom of susuharai (煤払い), or soot-sweeping, which was performed to purify the home before the new year. Modern ōsouji involves scrubbing places that are neglected the rest of the year — behind appliances, inside cabinets, along window tracks — and the practice is taken seriously enough that cleaning product companies run ōsouji advertising campaigns every December.
In Zen Buddhism and certain martial arts traditions, souji is practiced as a form of moving meditation called samu (作務). Monks sweep temple grounds not just to keep them clean but as a discipline that cultivates mindfulness and a non-attached mind. This connection between physical cleaning and mental clarity has influenced workplaces and homes well beyond religious settings, and the idea that a tidy space reflects a settled mind remains a recognizable cultural assumption in Japan.
