Imosen

Under a highway in Shinbashi is not where you expect a yakiimo specialist, which is the point. Imosen offers multiple varieties like Beniharuka and Silk Sweet – softer and lighter, more melt than jam –  plus sweets made from their house-roasted potato paste.

This is one of the few spots that offers a coveted and creamy purple yakiimo from time to time, but you’ll have to stalk their socials to figure out what’s on offer that day. If you find yourself out late downtown and need something delicious and portable to warm up with, you’re in luck: Imosen keeps late hours.
