Ginroku Imo

At Ginroku Imo in Koyama, Shinagawa City, sweet potatoes are suspended inside a specially made clay pot and slowly roasted over charcoal, whose far-infrared heat cooks them through. The result is a crisp, fragrant skin and a moist, richly sweet centre. The menu features varieties with distinct qualities: Beni Haruka and Silk Sweet are known for their smooth sweetness, while Naruto Kintoki and Beni Azuma have the fluffy texture and traditional flavour of old-fashioned sweet potatoes. Anno Kogane is among the other varieties on offer. Choose a size from small to extra large to suit your appetite.

A potage-like latte and a shake that puts sweet potato first

The appeal here extends beyond the roasted potatoes themselves to drinks and sweets made with sweet potato. The clay-pot-roasted sweet potato shake blends roasted sweet potato with milk; its natural sweetness and fine, refreshing chill make it a pleasant way to quench your thirst during a walk. The hot roasted sweet potato latte, meanwhile, is so rich and creamy it brings potage to mind, with the sweet potato’s full aroma coming through clearly. Coffee made with a specialty blend from Horiguchi Coffee and Japanese tea are also available, offering good companions to the potatoes’ sweetness.

A place to pause or pick up a treat to go

There is seating inside, where you can settle in and enjoy your order in a relaxed setting. Takeaway and collection at the shopfront are also available, making it easy to pick up a snack when you are hungry or a drink to enjoy on a stroll.
