Naruto Taiyaki Honpo Sonezaki is a Japanese confectionery in Ohastsu Tenjin Shinmidosuji in Umeda, Osaka, where taiyaki is grilled over an open flame. Each taiyaki is filled with red bean paste, custard cream, or sweet potato paste inside a thin, crisp shell, and ice cream monaka is also served. Craftsmen grill the taiyaki one at a time, so waits depend on timing, though the line moves quickly. Prices run higher than Korean bungeoppang.
