Tanaken (@ec8531) is a Japanese-language YouTube channel from Japan about selling online, especially on Amazon, Rakuten and TikTok Shop. The host founded the Amazon consulting firm GROOVE, and episodes cover advertising, product pages, AI adoption and interviews with guests from agencies and trading companies. It posts about three times a week, pairing 10 to 40 minute talks with clips of one to two minutes.
The channel has about 50,000 subscribers and a median of 1,300 views per video, with the strongest recent videos reaching 4,000 to 8,000. Viewers are most likely sellers, brand managers and marketers in Japan; audience figures here are estimates. No paid sponsorships were detected, and the channel promotes its own company, a book and a LINE account.
At the $225 to $525 range, the midpoint implies a CPM near $286 against the $10 paid norm, so it suits a narrow B2B buyer rather than reach. Software, agency and logistics firms selling to Japanese ecommerce sellers should consider it.
