Well, I’m currently reading a 21 (?) volume long light novel series, so that’s what I’m reading! XD So for best reading in Japanese in 2022, it’s Flesh & Blood! 
(I’m currently on volume 7! woot)
It’s a roller-coaster type of story, with light-heartedness and bro- and romance, mixed with frightening seriousness. Lots of historical realism and real personas, but these books manage to avoid getting too bogged down by it. Natsuki Matsuoka paves her own path with these ingredients, creating a compelling historical drama, with a big focus on political intrigue and the big conflict between Christian faiths in Europe at this time, protestantism/catholicism - with a side serving of life on the sea!
