About はてなび
はてなび is a Japanese YouTube channel run by Citrus Net, Inc. that publishes short kanji and brain-training quizzes. Most videos are vertical Shorts of about 15 seconds, with a timed fill-in-the-blank format that repeats across uploads. The channel has roughly 1,600 subscribers and a median of about 940 views per video, based on its recent 30 uploads. Its viewers are most likely Japanese adults interested in learning kanji and keeping their minds active; this audience profile is an estimate. The channel has not posted in over a year, and its sponsorship history is empty. At $150 to $250 per video, the rate works out to roughly $160 to $270 per 1,000 median views, far above the typical $10 to $30 CPM for paid ads, so it suits small, test-sized campaigns from education brands.
The channel does not show any brand partnerships in its recent work. Its format fits Japanese language apps, study materials, and brain-health products that want a small, focused audience rather than mass reach. Brands should check current activity before committing budget.
