Towards the end of 2015, Nakata entered into a partnership with Kee Club in Hong Kong to open Koko, a Hong Kong-based restaurant that serves sakes created by Nakata himself. He has developed his own line of sake as well as creating his own mobile educational app, "Sakenomy". Expressing interest in educating the public about sake, Nakata stated, "People recognise brands of wine but not usually brands of sake. There is a lack of information and branding when it comes to sake. That’s why I thought I needed to create a brand that people can recognise and understand. My purpose is to expand the market for all sake not just my own. You can pair any type of cuisine with sake. It can go with French, Italian, even Chinese food, not just Japanese cuisine."
