Yubari Merode is the practical place to meet the city's famous melon culture. In season, the direct-sales corner sells Yubari melons, while the shop keeps the theme going year-round with sweets, snacks, and melon soft serve.
It sits beside Shin-Yubari Station, which makes it useful even if you are passing through without a car. It is not grand, but it is a very Yubari stop.
