She continued her basketball development at Oka Gakuen, a high school located in Shōwa-ku, Nagoya.

The Antelopes offered her a platform to refine her perimeter game and to compete against seasoned professionals from the outset.
Her progression through the Toyota Antelopes system was steady, with each season bringing expanded responsibilities on both ends of the floor. In parallel, her performances in domestic competition drew the attention of Japan’s national team program selectors, opening the door to international opportunities.
