Is this product safe to put in a microwave? Can I put water in it, then microwave it with the cover off in order to heat it?

It's not intended to be microwaved so the answer is, it would not be safe in the microwave. You have to put boiling water into the Yutonpo and you should fill it all the way to the top. This is a very safe product and I would highly recommend for you to buy it! I own several and use it every winter and for emergency situations. It really keeps you very warm and it beats using the electric blanket that are not safe to use.

There are no english instructions but japanese instructions on the cap. what do these japanese instructions or warnings say on the cap?

We've been using ours for about 8 years now. Basically this is how it works: 1) Boil water in kettle 2) Fill it to about 90% full, water should still slosh around a bit, and it should be below the cap. 3) Screw the cap on tightly. Tip it upright and make sure it doesn't leak any water. 4) Slide it into the cloth pocket for it. 5) Slip it between the covers on the bed. 6) Enjoy warmth for about 6 hours. 7) Drain it and clean it out with some chlorine twice a year or so. Hope this helps.

Does this come with the cover also?

The one I purchased came with a bright orange, fuzzy cover.

is the product medium or large size?

I don’t know how many sizes the company offers. The item (hot water bottle) I purchased in 2017 was medium. It’s not a large size since I bought at the Japanese grocery store in Los Angeles previously was larger. But they are the best Hot water bottle so far.
