For the most part, Japan takes personal hygiene pretty seriously. Combing your hair, putting on makeup, and getting dressed in the proper attire are all seen as essential parts of getting ready to go out in public, and dress codes are a much bigger deal than in some countries.
The standard grooming routine runs into one pretty big problem in the summer, though. Since most people in Japan take a bath at night before going to bed, by the time they arrive at work or school the next day, several hours have passed, during which sweat, oil, and odors can build up on the body. To combat this, there’s a wide variety of fragrances and deodorants available in drug stores, with one brand in particular that’s being described as “the ideal scent for women.”
