Player Comments: I am very happy to be able to fight for Kumamoto as a member of the Kumamoto Volters for the 2026-27 season!

The 2025-26 season was a frustrating one for me personally, as I didn't get many opportunities to be on the court.

There were times I almost gave up, but thanks to my teammates and the VoltersRed fans, I was able to make it through the season without breaking, and I am very grateful.

I want to repay the VoltersRed fans who continued to support and stand by me in any situation.

I will fight this year with more determination than ever before, and I look forward to your continued passionate support.
