What is it?
Jaga butter is a hot steamed, boiled or baked potato split open so butter melts into the center. It is cooked throughout Japan but is especially identified with Hokkaido, the country's leading potato region and a major dairy producer.
No reliable primary source identifies a single inventor, first shop or precise birthplace. It is best understood as a simple way of tasting two products closely associated with Hokkaido rather than as one restaurant's creation.
History and local context
The Hokkaido Government says the prefecture produces about 80 percent of Japan's potato harvest and grows roughly fifty varieties, including Danshaku and May Queen. Floury Danshaku and Kita Akari break into a fluffy texture, while waxier May Queen is smoother and holds its shape.
A processed product called Bata Jaga has been made in Minamifurano since 1993 with whole Danshaku potatoes and Hokkaido butter, but that product history is not the origin of the wider dish. In southern Hokkaido, a little salty fermented squid called ika shiokara is also a known optional topping.
How to enjoy it
Eat the potato immediately while butter can run into the cut center. Begin with butter and a little salt to understand the variety, then add shiokara one bite at a time if you want the southern Hokkaido combination.
At home, steam evenly sized potatoes until a skewer reaches the center without resistance. Remove sprouts and green skin, and follow safe microwave handling if using that method.
Availability varies by maker, season, and destination.
