Video games, like any other popular form of art, can be excellent advertisements for tourism. I always get the bug to browse flights after playing a new Assassin's Creed, for instance, and I don't think that's a coincidence. On the back of Ghost of Yotei, the eponymous Yotei area of Hokkaido is pushing for more visitors, apparently signing a deal to sell associated merchandise to curious travelers.
According to Japanese outlet Nikkei, Niseko, a resort town for skiing in the area, has entered into an agreement with Sony through a third-party firm to produce a line of Ghost of Yotei items visitors can buy. The first iteration of this agreement is a set of wooden knick-knacks from Kumagera Seisakusho, a producer of pendants, fridge magnets and other products that use locally sourced timber.
