# Tenkaichi Junior

Tenkaichi Junior (天下一Jr., Tenkaichi Junior) is an annual professional wrestling round-robin tournament held by Pro Wrestling Zero1 to determine the top junior heavyweight wrestler in the promotion, typically contested in late November/December. In addition to Zero1 members, it has frequently included outside stars, mainly freelancers performing in the Japanese independent scene.
The tournament has lately been presented as featuring two blocks, each with five participants, with the two block winners facing off in the final to determine the overall champion. In 2002, from 2006 to 2016, and between 2018 and 2019, the tournament featured only knock-out stages.
