Japanese karate has a special system of respectful forms of address. In Kyokushinkai these traditions are considered an important part of a student’s upbringing.

Core forms of address:
– sensei – teacher;
– sempai – senior student;
– shihan – senior master;
– kancho – head of the organization;
– sosai – founder of the school.

During training karatekas also use:
– OSU / OSS – expression of respect and readiness;
– Rei – bow;
– Arigato gozaimasu – gratitude;
– Onegaishimasu – request to train.

Japanese etiquette helps to:
– maintain discipline;
– cultivate respect;
– preserve Kyokushinkai traditions.

This is why proper forms of address are considered an essential part of the philosophy of Japanese karate.
