First i want to say Congratulations on releasing the game in JP.
Now onto the remark/suggestion .
We learned that the in the JP version there will be gameplay difference with GLB , honestly i don't think thats a good idea community wise , all currently available community ressource (guide,tier list and other) will be complitely worthless for the JP crowd and in the future JP made ressource will be useless to the GLB crowd , i feel like splitting the community is a really bad idea(they also have their own discord server ?!).It could just be like other gacha game , being 1/2 year(or less depending on update speed) late and just following a similar update schedule as the GLB version(or an accelerated one) that way JP and GLB players can communicate and relate.
Thanks for reading my concern about this segregation of community
