Gion Tsujiri's Tokyo Skytree Town Solamachi store has been selling a limited-time To go menu "Valentine Soft" from January 17th. The price is 780 yen (tax included).
This is a menu of rich Uji matcha soft serve ice cream with "Gatobubu matcha chocolate crunch" topped with three types of hearts: macaroons, hazelnut jelly, and raspberry mousse. Inside the cup is a two-layered raspberry jelly and roasted green tea mousse. It's a slightly sweet and sour "taste of love".
