When I perform a game search with "Japan" selected from the Region dropdown menu and "zelda" (without quotes) typed into the Name box I don't see the Switch version of The Legend of Zelda: Breath of the Wild on the list.
I'd also like to voice my support for the reintegration of regional sales data in the main database view. I liked to compare overall sales vs regional sales for games in a series. An alternative would be to add a series tag to each game and a series page that lists the games included in the series and their sales data.
Regardless, thanks for the great work!
