Japan's isolationist policy during the Edo period limited contact with the outside world but allowed for the development of unique cultural practices and traditions.

Okonomiyaki, a savory pancake made with various ingredients such as vegetables, meat, and seafood, is a popular Japanese comfort food.

Tennis is also popular in Japan, with several Japanese players competing at the highest level of the sport, including Naomi Osaka and Kei Nishikori.
