YJYOYO Club
YJYOYO Club (와이제이요요클럽) is a South Korean yo-yo company, academy, and retail operation founded in 2014 by Yoon Jong Ki — a Korean 2A national champion whose YouTube channel and instructional content helped drive a yo-yo boom in Korea. The company designs and machines original yo-yos ranging from 3D-printed beginner models and accessible full-metal entry points to high-end bimetals and tri-material flagship throws. Their team spans Korea, Japan, Czech Republic, and Singapore, with signature players competing across 1A, 2A, 3A, 4A, and 5A divisions — including Korean 1A champion Park Woo-chan and speed specialist Nam Dong-hun.
