Time Out says
Minatoya, a takoyaki shop along one of Sasazuka's shopping arcades, sells Amazake Shaved Ice, a nutrient-rich kakigori (it has been called 'the drinkable IV') with syrup made from fermented rice – it's naturally sweet, which means no sugar is added – and ginger slices on top. If you order any of their kakigori with fruit or vegetable-based toppings, you'll be pleased to know that all ingredients are blended up fresh as you order.
