MochiKanji is a Japanese-learning app focused on kanji and vocabulary, using spaced repetition and timed review reminders to help learners memorize characters faster.
It launched back in 2019, but only started pushing content in 2025, and that recent founder-led/social push helped it reach ~$10K MRR last month.
They are running a small TikTok UGC network composed of 7 accounts.
Despite only generating 1.4M total views, the videos stand out for their way above average engagement rates.
The actual 5 best-performing videos come from the same creator: @momochijapanese. She has made a total of 800K views across 40 videos.
The best-performing one hit over 72K likes, 500 comments and 14K bookmarks across just 350K views.
“why are you studying japanese so much?”
It opens with faceless study footage, then flips to “this is why” and shows her life in Japan. It works as motivation more than a demo. The video sells the outcome of learning Japanese, living there, experiencing the culture, which makes people curious about the app she used to get there.
In another well-performing video, she used the “kanji” app theme in order to retain people with a relatable struggle hook:
“when you only know hiragana, katakana but NOT kanji”
It opens with a bookstore clip, then cuts to Japanese street signs with half the characters blurred, recreating the feeling of not knowing kanji, one of the three writing systems. It then flips to “time to lock in” and shows app demo footage, which adds a clear study payoff and leaves users curious about the tool.
MochiKanji is currently sitting in the Top 100 in Education across 12 countries.
We’ll keep tracking it to see whether they find another format that works as well.
