Usually, Japanese schools will hold ‘Cultural Festivals’ that may incorporate both traditional and modern culture. Typically, museums will have special events based around Japanese culture, parades will occur here and there, and people who have distinguished themselves in the fields of education and the arts may be presented with awards on this day.
The Japanese certainly have a lot of wonderful culture and customs worthy of celebration. Even outside of Japan, certain facets of Japanese culture have become extremely popular, especially with regard to Japanese food. Sushi, Suki-yaki, Tempura and Teppan-yaki restaurants have enjoyed much success overseas, and millions of people around the world have become familiar with green tea. The majority of schools in Australia teach Japanese language, and along with that the students are exposed to various aspects of Japanese culture.
When I taught Japanese language in Queensland, Australia, my students loved watching videos of Sumo wrestling. Martial Arts from Japan, including Judo, Karate, Aikido, and to a lesser extent, Kendo, Iaido (live-blade sword) and Jujutsu are seen in Dojo’s (martial art training halls) in many numerous countries now.
