We are delighted to provide Butterfly brand uniforms and other items for all men's and women's teams in the T.League for the 2025-2026 season. It is the 6th season for men and the 4th season for women.
In the previous season (2024-2025), we were able to engage in a variety of exciting initiatives together with the T.League, that were well received by many fans. For instance, Butterfly's table tennis hero “Glayzerman” appeared at the opening match, and official matches were held at the Butterfly Arena in Yanai City, Yamaguchi Prefecture. We will continue working on bringing everyone the excitement of both the T.League and the sport of table tennis.
