Saturdays and Sundays are generally days off and there are also many public holidays, but some workers in service industries and real estate have their days off during the week and spend the weekend working.

In 2026, the standard workweek in Japan is Monday through Friday, with Saturdays and Sundays officially designated as days off for most office workers and government employees. However, Japan’s work culture is complex; while the "legal" hours are 40 per week, "service overtime" remains a common social pressure in many traditional companies. To combat this, the Japanese government has been actively promoting a four-day workweek recommendation since 2021, encouraging companies like Panasonic and Fast Retailing (Uniqlo) to offer more flexible schedules. For travelers, it is important to know that while office workers are off, retail stores, restaurants, and tourist attractions are not; in fact, weekends are the busiest times for these venues. Additionally, Japan has a high number of public holidays (16 per year), and if a holiday falls on a Sunday, the following Monday is observed as a day off, which can lead to "long weekends" that see massive crowds at major shrines and theme parks.
