The tokai gi is a traditional uniform worn by karate practitioners in Japan. It is considered an essential part of the martial art's attire and is often worn to competitions, demonstrations, and other events.

A tokai gi typically consists of:

• Long-sleeved vest with a front slit
• Shorts or pants with a slit at the knee
• Belts with various sizes and types (e.g. "tachi" belts for beginners, "yukon" belts for intermediate practitioners)

The tokai gi has a long history in karate, dating back to the early 20th century. It was originally designed to be worn with traditional Japanese clothing and martial arts attire.
