The international WNA nunchaku-do seminar that was planned for August 30 and 31, 2025 is postponed to 2026. The Dutch Grand Prix F1 will take place in Zandvoort on the weekend of August 30 and 31. Zandvoort is close to Amstelveen, which means that flights to the Netherlands and hotels in the region are not available for visitors and participants of the seminar. We hope that all interested parties can wait until 2026.
