Hi,
I’m probably not representative of the folks studying Japanese here, but it seems like there is room for podcast or youtube content using more accessible language, perhaps targeting intermediate level learners.
In Spanish it seems that there are many interesting and accessible podcasts/YouTube Channels that I can enjoy even with my level (B2). There are the language learning focused ones like How to Spanish, No Hay Tos, Españolistos, Español con Juan, Aprende Mexico, Dreaming Spanish, etc. There is also much native oriented content that is accessible to intermediate learners like El hilo, Bully Magnets, Hemisphero Derecho, Alan X el mundo, Lethal Crysis, Jorge De León, etc.
I’m not sure how much comparable content there is in Japanese.
Of the Japanese podcasts I listen to, I think the Bilingual News podcast could be a great listen to those studying Japanese. Others I listen to seem like they’d be really challenging (あんまり役に立たない日本史, 格闘キャスト, 今朝の三枚おろし, 歴史を面白く学ぶコテンラジオ) unless you already Japanese very well.
It seems like there would be room for a broad range of content like the Spanish ones in Japanese.
あくまでも一意見なので、参考までに
