Shiroi Koibito is the Hokkaido meibutsu that fills overhead bins on every flight out of New Chitose. A thin butter cookie sandwiching white chocolate doesn't sound dramatic, but this one has a name taken from a ski trip, a scandal that shut it down, and a lawsuit against Japan's biggest comedy company.
The cookie itself is a langue de chat sandwich with white chocolate inside. It's light, crisp, and very sweet. Made by Sapporo confectioner Ishiya since 1976, it's mostly sold within Hokkaido, which is exactly why everyone brings it home.
Shiroi Koibito Park sits at the end of the Tozai subway line in Miyanosawa, a quiet residential part of western Sapporo. The building looks like a European fantasy castle dropped into a suburb, with a clock tower that puts on a little show on the hour.
Inside, you can see part of the production line and do a cookie-making workshop. It's family-friendly and photogenic. It's also very much a branded attraction, not a gritty factory tour.
The name comes from a founder's line after skiing, when he said white "lovers" were falling from the sky, meaning snow. Shiroi Koibito-tachi was also the Japanese title of the documentary about the 1968 Grenoble Winter Olympics.
In 2007, Ishiya admitted to falsifying expiration dates on returned stock. Sales were halted for months and the president resigned. The brand recovered, which says a lot about how attached people are to it.
Then in 2011, Ishiya sued Yoshimoto Kogyo's group over a parody souvenir called Omoshiroi Koibito ("Funny Lovers") sold in Osaka. They settled in 2013, with the parody changing its packaging and limiting where it was sold.
Shiroi Koibito rides on Hokkaido's dairy reputation. The island is Japan's dairy heartland, and Sapporo's sweets scene, including Rokkatei's raisin butter sandwiches and Royce chocolate, is built on it. Locals respect Shiroi Koibito but often have their own favorite souvenir, and it's not always this one.
The strongest pop culture links are the Grenoble documentary title and the Omoshiroi Koibito parody, which itself became a cult souvenir in Kansai. Ishiya also has ties to local soccer: the field next to the park is the Miyanosawa Shiroi Koibito soccer ground, used by Hokkaido Consadole Sapporo.
You can buy Shiroi Koibito all over Hokkaido: Sapporo department stores, station shops, souvenir stores. The airport just has the biggest piles. Outside Hokkaido it's limited, though some Hokkaido antenna shops and online channels carry it. No need to panic-buy at New Chitose.
