意思

A room that is not clean or tidy.

🌍

文化背景

School children in Japan are responsible for cleaning their own classrooms (Soji). This instills a lifelong aversion to a '{汚|きたな}い{部屋|へや}'. The 'Genkan' (entrance) is the most important part of the house to keep clean. A '{汚|きたな}い{玄関|げんかん}' is considered much worse than a '{汚|きたな}い{部屋|へや}'. The concept of 'Danshari' (refuse, dispose, separate) became a huge trend in Japan to combat the problem of cluttered rooms. The 'Depression Room' trend on social media has made people more comfortable sharing photos of their '{汚|きたな}い{部屋|へや}' to reduce stigma around mental health.
