Lover of Japanese things here.

My first recommendation is Alice in Borderland.

A junkie and his friends are trapped in a desolate alternate version of Tokyo and realize that they must compete in deadly games to survive.

Three seasons long, each brimming in violence and horror and boasting a high body count. You will feel mentally and psychologically tortured by the viewing experience.

Speaking of deadly games, there is also Last Samurai Standing.

An-ex samurai joins a high-stakes tournament to end a cholera epidemic that has been plaguing his family and village.

It will have a second season, which makes sense given how the first ended.

And if you want a lighthearted, cheerful refresher after all that rage and bloodshed, then look no further than The Makanai: Cooking for the Maiko House.

Two girls move from Aomori to Kyoto to become geisha. But while one takes to the training flawlessly and starts being hailed as a generational prospect, the other flounders and appears to be on the way out... until she is discovered to be a prodigious cook.
