Mochi ice cream is a Japanese dessert: a ball of ice cream wrapped in a thin layer of mochi, a soft and chewy rice dough. At Kyōyo Haus the mochi is made by hand every morning and wrapped around the ice cream the same day, so the exterior stays thin, soft, and fresh instead of firm like frozen store-bought mochi ice cream.

Kyōyo Haus is located at 36 JFK Street, Inside The Garage Mall, First Floor, Harvard Square, Cambridge, MA 02138.

Monday through Thursday 1:00 pm to 8:30 pm. Friday and Saturday 12:00 pm to 9:00 pm. Sunday 12:00 pm to 8:30 pm.

Kyōyo Haus serves mochi ice cream, matcha soft serve, ichigo daifuku, and Japanese lattes including matcha, hojicha, black sesame, pandan, and ube, plus cream-capped drinks like the Coco Matcha Cloud and the Shio Cold Brew. Seasonal yuzu refreshers and a rotating monthly flavor round it out.

The current featured flavor is Banana Milk ($7.50), available as mochi ice cream and soft serve. Three flavors never change (matcha, black sesame, and mango); the other three slots rotate, with a new flavor arriving about once a month. A previous drop, Peach Oolong, is still on the menu in one of the rotating slots.

The lineup holds six flavors. Three never change: matcha, black sesame, and mango. The other three rotate, with a new flavor arriving about once a month; right now the rotation is lychee, peach oolong, and banana milk. Every piece is made fresh the morning it is sold.

Yes. Kyōyo Haus serves Japanese-style soft serve (soft cream) in the same six-flavor lineup as the mochi ice cream: matcha, black sesame, and mango always, plus three rotating flavors. Most come with an included pipette pairing, and some with toppings like coconut jelly (nata de coco) or coarse sugar.

Kyōyo Haus makes mochi ice cream fresh every morning in Harvard Square, Cambridge, a few stops from downtown Boston on the MBTA Red Line. Each piece is wrapped by hand and sold the same day it is made, never carried over.

The tea lattes are the vegan side of the menu: matcha, hojicha, black sesame, lychee matcha, and hojicha matcha are vegan ordered with oat milk and without the cold foam or soft serve add-ons. Pandan and ube are not, because the condensed milk is inside the concentrate and an oat milk swap does not remove it. The capped drinks (Coco Matcha Cloud, Coco Hojicha Cloud, Sesame Hojicha Latte, and Shio Cold Brew) are not vegan or dairy-free either, even with oat milk, because the cap is cream. The yuzu ades are vegetarian rather than vegan: both bases contain honey. The mochi is not vegan either, since the dough is made with milk.

We don't use peanuts or tree nuts in our facility. Our soft serve mix and flavour bases are made in a supplier's plant that also processes egg, wheat, peanut and tree nuts. The soft serve and the mochi contain milk and soy. Our recipes use no gluten-containing ingredients except the cream cap and cold foam, which contain barley malt, and the Banana Milk pipette, which contains a malt syrup; ask us. The cream cap is on the Coco Matcha Cloud, Coco Hojicha Cloud, Sesame Hojicha Latte, and Shio Cold Brew, and the cold foam comes as the Matcha Mochi Cold Foam and Mochi Cold Foam add-ons. The kitchen handles dairy, soy, sesame, coconut and oats.

Vegetarian, yes. Vegan, no. The mochi dough is made with milk, and the filling is dairy ice cream. For vegan choices, order a matcha, hojicha, or black sesame latte with oat milk and without the cold foam or soft serve add-ons. The yuzu ades are vegetarian rather than vegan: both bases contain honey.
