Make my own ice cream

I am a Foreigner with Tourist visa.So I can't buy freeze.
But I want to make my own ice cream.Do you know any portable Japanese ice cream maker?Any website is highly appreciated.

Most smaller bemch top ice cream makers require the tub to be put in a freezer for a few hours first.

Also add in the cost of buying the machine. Weird considering your short length of stay. I'm sure it'll outweigh the cost of buying from supermarket.

Also if you attempt to take it home. Heavy in luggage and only 100V.

Wow! You already have a cow? :)

As an option, why not check out tourist farms and see if you can find one that lets you get in on the act.

I am pretty sure you can make homemade ice cream here:

And yeah must ice cream machines require a freezer where you can put the bowl for a good 24 hours. I personally don't find my ice cream machines terribly heavy, but it is bulky.

Thanks so much.Do you think Japan has portable ice cream maker?

Yes Japan has portable ice cream maker. You didn't read the previous responses to your question.

But no a portable ice cream maker will not be suitable for your situation. Reasons explained in the previous responses also.

But note the power supply as most will be 100V.
