About 【減力塾】嘉山コマ
Komazo Kayama runs the Japanese YouTube channel Gensuryoku-juku, which mixes comedy with ghost-spot visits and a long-running late-night radio series called Night Radio. Based in Japan, the channel has about 3,180 subscribers, and its uploads have slowed to roughly one video a year in the past twelve months.
The content is mostly Japanese-language, with long episodes of banter and occasional short clips. Viewers are estimated to be mostly Japanese adults, leaning male, who enjoy late-night talk and paranormal storytelling. These audience figures are estimates based on content and titles, not verified analytics.
Brand work has not been seen on the channel. The median view count is low, so a sponsored integration would be priced at roughly $150 to $250 per video, well above what the audience size justifies at a CPM of $20 to $35 per 1,000 views, compared with the $10 typical for paid ads. Brands seeking a small, niche Japanese audience should book this creator, but expect modest reach.
