Isuzu Cup (Muay Thai)

The tournament is organized by the Tri-Petch Group, owned by Isuzu Motors Ltd.,[1] and sanctioned by the Sports Authority of Thailand.

[3] The first Isuzu tournament started in late 1990 under the management of Damrong Puttan and Songchai Rattanasuban at Omnoi Stadium.

[4] In 2011, as the Tri-Petch Group became a sponsor of the new Thai Fight promotion, which aims for higher-weight talent, the tournament weight was raised to over 135 lbs for the first time.

In 2023, the tournament was moved away from Siam Omnoi Stadium for the first time since 1993, as it was entirely fought in a studio at BITEC Bangna in the Thai Fight promotion.

Each region of Thailand would put forward a team of three fighters, one for each contested weight: 143, 147, 152 lbs.
