Tabelog ratingKansho Marenoya (甘藷まれのや) is a charming, one-of-a-kind sweet potato snack shop operating out of a converted garage in Kamata, easily identified by the distinctive pink Volkswagen van parked out front. It specializes in a small, focused menu of handcrafted treats, with the star attraction being the daigaku-imo, or candied 'university sweet potato'.
What sets this version apart is that it's made to order. The syrup is poured over the warm potato pieces just before serving, creating a thin, perfectly crackly shell over a soft and fluffy interior. Guests consistently praise this delightful texture contrast. Another favourite is the intensely glazed and addictive usugiri, which are paper-thin, crisp sweet potato chips. The shop also offers simpler baked sweet potatoes and a plain but high-quality sweet potato cake (スイートポテト).
The main drawback is its popularity and limited stock; popular items often sell out by late afternoon, so an early visit is recommended. A few reviewers have noted minor inconsistencies in texture, and some find the single-serving portions a little pricey for their size. However, most visitors consider it good value for a freshly prepared, artisanal snack served by a friendly owner.
As a budget-friendly takeaway spot, prices are modest. Reviewers in 2026 paid around ¥500 for a small portion of daigaku-imo, while the usugiri chips were noted at ¥400–¥500 between 2023 and 2025. The sweet potato cake has been cited at around ¥130–¥150.
