My husband speaks Japanese, and from time to time we tried to find Japanese movies, but never came across much. Four years ago we were introduced to Korean dramas by our daughter-in-law and her mother, and that was amazing because there was so much available. There are companies that provide Asian dramas! Wow! We watched them and enjoyed them but eventually we said, “Aren’t there some Japanese dramas too?”
It turns out that there are, in the same places that offer other Asian dramas. Not as many as Korean ones, and they are slower to get subtitles. But they are out there.
