How do I change to the Japanese server on XBOX?

Hi, i recently started playing on Xbox in Japan and there is no server for it on xbox but there is one on steam. How do I change it?

weird even the devs dont answer this

I am sure there is A Japanese server on Xbox. Because I have seen it when I want to change my server to Hk ~~I think that problem is just like I can't find Hk server on that list. Maybe we should switch language to english ,then re-download the game. I'll try this way tonight.
