Adidas custom Shirt sizes in Adidas Store Shibuya?

Hi, I’ll be in Japan in two weeks and plan to design my own shirt at the Adidas store in Shibuya. Does anyone know what sizes they offer for the customised shirts there? From what I understand, Japanese stores often carry smaller sizes compared to European/US “XL”. Has anyone had experience with this store (or similar) and can advise on sizing?
