Onsen manju, sweet steamed buns filled with red bean paste, are a beloved snack found across Japan’s hot spring towns, but Kusatsu’s version carries a particular local charm — traditionally, some shops cooked the buns using steam vented directly from the town’s natural hot springs rather than conventional kitchen equipment. Dozens of shops around the Yubatake sell warm, freshly steamed manju, each with slight variations in dough colour, sweetness, and bean paste texture, making a comparison tasting a popular activity for visitors strolling the town.

Manju are best eaten warm and fresh — buy from shops with visible steam and a queue of locals rather than pre-packaged options. Trying a few different shops' versions side by side is a fun, low-cost way to sample the town’s variety.
