Okawaya

Found just around the corner from the Kira Mansion Ruins in Ryogoku, this venerable wagashi shop has been in business since the Meiji era. Their creations include the popular Sumida River Monaka, a bird-shaped cookie sandwich filled with bean paste, and the Kira Manju, themed on the treacherous noble of the same name. Make sure to also look out for their seasonal confectionery, which is a treat for both the eyes and the taste buds.
