We are talking about first day sales here, of a game that's propably not supposed to sell in big numbers. Only time will tell how this game performs.
But there is atleast one thing in the game, that usually don't sell in Japan, such as the main character being an ex-superhero (in Japan, anime characters that are considered as weak, sell a lot better).
And on top of that, the title haven't had marketing, the genre is what you could call niche these days (even SMG and TP underperfomed in Japan) and it's a new IP.
As for the games story, i think it has similarities with X-men comics, since all the characters seem to be problematic with their past, just like Nick(?)/Captain Rainbow apparently is.
