Japanese dramas are relatively short, and a few have two, but the most touching ones in total are more than 20. The most famous one is of course "One Liter of Tears". I heard that after it was broadcast in Japan, the touching friendship dramas made the people shed tears.
"Wild Boar Makeover" is the kind of continuous light touch, and it is also a bit funny and touching. There is "Only Love". Although the ratings are not high, I think it is good. There is a touch of sadness and touching after watching it.
Those whose deeds and lives are touching include: "Song of the Sun" starring Erika Sawajiri and "Courage" starring Kamenashi Kazuya
