Lab Exploration Program
Lab Exploration Program (LEP) is a yo-yo brand based in Kanagawa, Japan, with operations spanning Japan and China. The brand launched in 2021 with the ONIGOKKO, a signature model for Chinese national champion Wu Congcong, and established itself in the competitive scene through technically ambitious designs and close collaboration with top international players.
LEP operates under two lines: the primary LEP brand and the JIGUN sub-brand, which covers the full range from entry-level plastic throws to ultra-premium titanium and magnesium models. The brand is known for innovations including tri-material constructions (aluminum + polycarbonate + titanium or stainless steel rings), patented POM rim designs (New Moon), the YOFO hybrid yo-yo/spin-top, and the KAWA off-string yo-yo. All products are sold through LEP’s Shopify storefront at labexplorationprogram.com. Key signature players include Wu Congcong (Chinese national champion), Hu Congcong (Chinese champion), Wayne Chung Cheng Hsun (9-time Taiwan champion), Yulin Li “Luckey” (multi-national champion), and Zhang Suze.
