Method #1: Inspect the Label and Embroidery

A genuine Tokaido Karate gi will have a label that reads "Tokaido Karate" or "TK" in Japanese characters. The embroidery on your gi should also match the style and design of the official Tokaido Karate logo.

Method #2: Check for Serial Numbers

Most authentic Tokaido Karate gi manufacturers will have a serial number printed on the inside of the legging or sleeve. These numbers can be found online or through authorized dealers.

Method #3: Look for Quality Control Marks

Reputable manufacturers may include quality control marks, such as a seal or sticker, to indicate that their gi meets certain standards of quality and authenticity.

Method #4: Examine the Fabric and Weave

Tokaido Karate gi fabric is typically made from a specific type of cotton called "saccharose" or "sacharose". The weave should also match the style and design of the official Tokaido Karate logo.

Method #5: Check for Certification

Look for certification from organizations such as the Japan Karate Federation (JKF) or the International Organization for Standardization (ISO). These certifications can provide assurance that your gi meets certain standards of quality and authenticity.
