Returning to the States with a Rice Cooker

I will be returning to the States with a rice cooker in a month and a half.

Does anyone have experience bringing one back? I'd like to put it in my luggage, but I would have to buy a suitcase large enough to fit it. I already need to buy another suitcase, but I'm worried about finding one that will both fit airline specifications and the dimensions of the rice cooker.

Or do you think it would arrive safely to my home in America if I shipped it through the mail? I still have all the shipping materials that were used when it was delivered to me.

Is the rice cooker rated for 120V? Japan uses 100V and the difference may be detrimental to the operation of the appliance.

I have a voltage converter.

But I'm asking specifically if anyone has experience taking one to the States and how they did it. Not anything about the appliance itself.

Send it by mail. 45 years ago I mailed a motorcycle back to the US by mail.

EMS reasonable/reliable.

We bought a rice cooker in Tokyo 20 years ago and brought it with us in our hand luggage.
Bought the cooker in one of the shops in Akihabara. There are many shops there selling appliances made for export to the USA.
Still works like a charm :-)
