About オンライン教室言葉の森
言葉の森 (@kotobanomori7) is a Japanese channel run by an online writing school of the same name, founded in 1981 and based in Yokohama. According to its website (mori7.com), it teaches composition from grade 1 to grade 12 through five-person online classes and a writing test that uses the school's own scoring software. The channel posts long-form lectures of about 8 to 12 minutes on writing, reading, study methods and education policy, mostly without on-camera presence, roughly once a week.
The audience is estimated to be mainly Japanese parents and students, with an older skew, but this is not measured. Views are low, with a median of about 31 per video and roughly 1,140 subscribers, so reach is small.
Brands with a narrow education offering targeting Japanese families may find the channel relevant. At an estimated $20 to $35 per 1,000 median views, a sponsored video would cost about $150 to $250, a CPM comparable to paid ads at $10 to $30 CPM, but on a much smaller audience.
