Where to find ice cream mochi in Tokyo?

Hi, I was wondering where can I find ice cream mochi in Tokyo? I heard they have regular mochi in the basements of department stores but what about ice cream mochi? Is there a famous or popular mochi company/brand in Tokyo? I am currently staying in Shinjuku and heard that the Mochicream closed down here.

Thanks!

The close from Tokyo is the Saitama shintoshin.
There is mochi cream corner to the supermarket of Life Saitama shintoshin shop.

Yukimi daifuku so, such as is available from autumn, it might be like on the convenience stores and supermarkets.

Yuki mi daifuku(雪見だいふく) is available at supermarkets and combini in ice cream/freezer around 160 Yen(2 ice cream mochi in a pack).
Buy a red label Yuki mi daifuku which vanilla ice cream in.

I was first introduced in Little Tokyo to Mikawaya, which makes mochi ice cream and other types of mochi, daifuku (mochi with bean paste filling), dango (like small flavoured mochi) and other interesting things like butter mochi and mochi moulded into different shapes.

The ice cream was my favourite though. They had quite an array of flavours, from vanilla, green tea, peach, to chocolate, coffee, pistachio...the outside is basically flavoured rice dough, kind of chewy/doughy/glutinous in texture, while the inside is ice cream. The best part is, it's okay even if the ice cream melts! As long as you take care not to let it splatter.

Since then I've found certain types of mochi ice cream at Oriental stores, most commonly those made by 'Lotte' a Korean/Japanese brand. A common one is known as 'Yukimi daifuku'
