Nice to meet you! When I was a junior high school student, I had a judo class twice a week in physical education for three years. This is a compulsory subject. Greetings before the fight, respect for the enemy team. Greetings to the referee. Everything started with a bow and ended with a bow. I made a lot of friends. I'm 70 years old now, but sometimes I go to the dojo and immerse myself in my memories.
