I bought a Zojirushi NP-ZF10-TD at the Costco in Tamasakai in January. I was shopping at the same Costco three weeks ago and saw it still in stock. The price is ¥18,777, and Costco will do tax-free sales if you present your passport.

The NP-ZF10-TD has been working fine at home in the US without using a step-down transformer. I suspect that the cooker's electronics automatically adjusts for the higher voltage. At some point I'll get around to measuring the actual electric draw to confirm.

It doesn't have an earthenware pot/nabe, but it does have the okoge scorched rice menu. I'll have to try it when I get home next week.

There is a Japanese manual, but no English manual that I could fund.
