I find asadoras to be a good choice. The 15 minute format means you can watch as many or as few as you want at a time. Generally I’ll watch 6 episodes at a time for 1.5 hours. The fastest I ever watched a drama was Amachan, 18-24 episodes a day for a week. Asadoras do tend to be 35-39 hours long and the 150+ episode count scares some people away.
I’ve watched
Amachan - young girl wants to be a diver and an Idol
Gegege No Nyobo - Based on the biography of the wife of mangaka Shigeru Mizuki.
Chiritotechin - a young woman dreams of becoming a comedian in the male dominated field of Rakugo.
Gochisousan - a young woman who lives to cook, struggles to win over her in laws with her cooking. Set before and during the Pacific war years, 1930s and 40s.
Many of the more recent ones are fully translated.
