Yes, I am fine with a Japanese language version if there is an online English manual somewhere - as long as it won't be damaged by the US electric standard, it is viable option and may even be cheaper.

The only thing holding up our decision right now is the concern about the pot becoming damaged if we cook other things - for example, we use our current rice cooker to make sweet potatoes and some one-pot dishes which mix meat and vegetables into the rice, but the current rice cooker is an old model that uses our own ceramic or metal bowl.

Not sure why the companies would advertise one-pot meals for their advanced rice cookers if that ends up damaging the machine.
