In Japan, several different sports are practiced. Traditional martial arts such as judo and kendo are popular, as are foreign sports like as baseball and soccer (football). In the summer, many Japanese people enjoy surfing or scuba diving, while skiing and snowboarding are popular winter activities. Japan is a nation of otaku (people who are obsessed with anime and manga), so it isn't surprising that gaming is also very popular here. Console games like Mario, Zelda, and Final Fantasy are international hits, and mobile phone games are increasingly popular too. In fact, in 2012, mobile phone games were found to be more profitable than movies! Japanese people love food, so it isn't surprising that restaurants and cafes are major employers in this field. Also, due to the popularity of sumo wrestling, sport hunting is another occupation for Japanese men. In fact, hunters are one of the few remaining groups of male-only occupations in Japan. Many businesses in Japan have two separate time zones: standard time and daylight saving time. This is because sunlight doesn't affect plant growth in temples, gardens, and funeral parlors, so they keep normal business hours even during winter months. Finally, Japan has a unique system where older people can retire before they reach 65 years old.
