Aloha! I live in Hawaii. I purchased Two sets of portal because I wanted to use portal with my son who lives in my son. Portal is BEST. My brother has been doing English school in Japan and he has more than 40 franchisees. Anyway we would like to use Portal but we are not sure if Portal works in Japan. Also do you sell Portal in Japan? If I can have an opportunity to talk to you, I really appreciate it. Mahalo
