【口ゴボ】一日で治せる外科矯正 セットバック整形 ～ Eライン整形で出っ歯や受け口も横顔美人に 

I don't think they have branches. but you can search "Set Back"（セットバック 東京）in Tokyo. I think nowadays many clinic do this treatment. But after watching the video, I feel like this clinic has pretty nice skils. So, you should go there to check it out because the appearance of people depends on doctor's skils. Even though I'm in the US now, I'll go there when I travel to Japan.

Thank you!
