A winery with over 50 years of history, known for "Tokachi Wine." Its official name is "Ikeda Town Grape and Wine Research Institute," and it is affectionately called "Wine Castle" because of its resemblance to medieval European castles. In the underground aging room, there are French oak barrels where wine sleeps quietly, as well as a number of old vintages. On the first floor, there is a shopping area where you can purchase Ikeda Town's specialties, including Tokachi wine, and on the fourth floor, there is a restaurant. This wine castle is full of fun.

There is a tour course starting from the first floor of the castle, which is open from 9:00 to 17:00. On the east side of the castle is a wine factory where you can see the wine bottling process.
