This rice ball speciality store is run by a chef who trained at the popular Onigiri Bongo in Otsuka. Yamataro’s onigiri are bigger than the ones at convenience stores, and they offer around two dozen varieties of filling ranging from the classic ume (pickled plum) and tuna mayo to more inventive options such unagi cream cheese and spicy ahi poke.
You can’t go wrong with any of the selections on the menu. But if you’re still undecided, go for the minced meat with egg yolk (¥400) and sujiko (salted salmon roe; ¥650). Better yet, combine two fillings into one rice ball for an additional ¥100 or so.
The onigiri at Yamataro will only set you back between ¥300 to ¥650. So splurge and make it a meal: add on a pork and vegetable miso soup for ¥360 and a side of palate-cleaning pickles for ¥150.
