In the labor law of Japan, the clearances determined by law are 4 days a month (houtei), I have no definition of days of the week, meaning these 4 days can be weekends or weekdays. And if the employee works on any of these 4 days the company should pay extra (overtime) of 35%. And it also has the clearances determined by the company (company calendar), called shoutei.
If the company has a daily schedule of less than 8 hours of work per day, ie 4 hours per day, and there is a need to work another two or four hours, up to the limit of 8 hours per day, the company is not obliged to pay overtime as overtime, only if the journey exceeds 8 hours per day.
