Tachiaoi Cup
The Aidu Chuo Hospital Tachiaoi Cup (立葵杯, "Hollyhock Cup") is a Japanese women's professional knockout tournament sponsored by Aidu Chuo Hospital. The hollyhock flower (tachiaoi) symbolizes ambition and reaching for the sky — an apt metaphor for women's Go, which has seen a renaissance in Japan with players like Ueno Asami breaking through to compete with men at the highest level.
