Clicking through my sub list these look to fall in the edutainment space:
- Ichiken Engineering
- ゆる言語学ラジオ (Linguistics but also a lot of rambling tbh)
- 世界ミステリー (bit of folk lore, bit of critical takes on conspiracies about history, bit of mythology)
- 丸山ゴンザレスの裏社会ジャーニー (dark side of Japan)
- ミッドナイトムーン (mostly history stuff)
- 北條元治 | 形成外科医・肌の再生医療の専門家 (dermatology)
- Criminal (true crime)
- 【消防防災】RESCUE HOUSE レスキューハウス (uh…how to not die in bad situations?
) - 囁き女官の館 (history)
- フェルミ漫画大学 (an anime girl explains self help books to you)
- 摩訶不思議浪漫の館 (history)
- ラムダ技術部 (science-y)
- ABCテレビニュース
- CBCドキュメンタリー
