Sony updated the official retailer store list of the PlayStation VR in Japan and from March 25, 2017 you can buy the VR device from more official shops in the country. As you know in Japan you can get the PS VR only from official retailers (shops, webshops) and looks like Sony expanded the partners. You can find the official list in here: http://www.jp.playstation.com/psvr/shop/index.html
