I don't tend to watch TV shows that are currently airing, as I prefer waiting until an entire season of something has been subbed and put up online (I worry that the subbing group will drop the show partway through 😰). At the moment I'm slowly working my way through Segodon, which was the taiga drama NHK aired in 2018. I think Segodon is the most recent taiga I've ever watched, since the show only finished on 16th Dec 2018, and we started watching it on 1st Jan 2019!
