RIONA TOMISHITA & SHION TSUJIMOTO Dominate at Okayama Super Taikyu Round

October 30, 2025

• RIONA TOMISHITA delivered when it mattered most, scoring her third ST-2 class win of the season with the #225 KTMS Toyota crew at Okayama. Starting 11th overall in wet conditions, the team methodically worked their way to the front, with TOMISHITA extending their lead during a crucial middle stint on slicks before handing off to teammate Suzuki for the victory. This clutch performance puts her just 11.5 points behind first place heading into the season finale – close enough to make things very interesting.
• SHION TSUJIMOTO continued her ST-Q class dominance, claiming her second consecutive win while helping Honda develop carbon-neutral fuel technology. Racing as the lone ST-Q representative in Group 1, TSUJIMOTO took over the #271 HRC Honda for the final stint and brought it home 20 seconds clear of the field. We love seeing a driver who can win races while literally helping build the future of motorsports – that’s the kind of multi-dimensional excellence women bring to racing.
• The weekend’s split format into two three-hour races showcased both women’s adaptability across different conditions and competition structures. TOMISHITA’s team executed a flawless wet-to-dry strategy in Group 2’s Sunday morning race, while TSUJIMOTO managed her stint perfectly in Group 1’s afternoon session. With TOMISHITA now firmly in championship contention and TSUJIMOTO on a winning streak, both drivers have positioned themselves as the ones to watch heading into the season’s final round.
