GJC Established 1951
Motto

Yudansha-Kai

Judo is unique. Unlike other sports, its competition and rewards are more personal. Its team spirit is the spirit of the mind and the body working together to achieve a common goal. This essential coordination of the mind and body is a prime factor in any successful human endeavor, and achieving the desired objective is difficult. There are times when a student's improvement will be slow, and their hopes disillusioned; but, perfection requires time, and time will yield to patience and perseverance, which are important virtues of judo (respect, character and doing your best).
