honestly, for how complex it looks on the outside, japanese grammar is dead simple. they offload a lot of it to vocabulary though, but that tends to be easier to learn i feel like

as a french native, i'm just glad i don't have to learn how some 25 tenses behave with 3 verb groups, and the bajillion exceptions there are for each

like, they have i believe ~3 verbs that don't always fit in the 2 groups all other uses. simple!
