Snowboarding in Yoyogi Park? We’re not kidding! It’s all to raise awareness about bone marrow transplants, initiated by professional boarder Yoshimasa “Daze” Arai. He overcame a near-fatal disease thanks to a successful bone marrow transplant, and now wishes to encourage donation through this snowboarding contest. A slope of snow will be brought into the park with a rail running down the middle. Snowboarders will show off their best tricks, and you’re invited to watch. Saturday will be for qualifying rounds, and Sunday is main draw for men’s, women’s, and junior divisions. There will be food and performances from musicians.
