My "mamachari" (bicycle). It's an orange bike and on the side it says "pretty fashion bike." It's got a basket and it's powerful -- I feel like I'm riding an ancient chariot to Mister Donut.
Warm toilet seats. Those automatic toilets, they really are the best thing in the world. If I was able to find one at home, I'd definitely get it. It's a lifetime investment.
I like the little pop culture things you can buy here that it's not easy to get at home, like the little "Nightmare before Christmas" purse that I bought today.
Hot cans of coffee in winter definitely or any hot vending machine products. At one point that stopped me going back to Scotland -- there's a market there just waiting to be cracked.
The robots I've seen here at the expo. The ones in the Toyota pavilion play a bunch of music. The one that played the trumpet was my favorite because it looked the most like a human.
The Mama coat. You wear the coat and you have the baby on the front and there's this extra piece that goes over the baby and which you can zip on to your coat.
