Metro Replacement Heater for Japanese Kotatsu 600

This warmer works perfectly. There's multiple heat settings that you can use. Buyer Beware: this product does use Japanese Voltage. Although similar to US, not exactly the same. As an amateur no nothing electrician, from what I understand, the Kotatsu will just run hotter because of the amount of US Volts. That is why I only keep it on the low settings, and it's plenty hot enough to enjoy. I don't think a converter is needed if you keep safe and use low settings.The item is simple, works, and is what I needed for DYI kotatsu. Also, if you have your own traditional frame, this will easily fit in the square to replace an old one.

古くなったので部品交換しました。取り付けも簡単で、スイッチ部分も操作楽々。細かく温度調整できるからいいですよ

I decided to turn my coffee table into a kotatsu, and bought this heater for the project. It was very easy to drill onto the bottom of my table. I left a 2 inch gap between the heater and the table, though it's probably not necessary to have that much space. During the winter I throw a comforter and a wood top over my coffee table and cozy up. During the summer, I simply unplug the cord and store it, you would never know the heater is there unless you're literally on the ground. The velvet coating is a nice touch as I occasionally brush my legs against it (and it never gets too hot!), and the wrapped cord feels to be made of quality. I live in the USA, so the electrical output is a little stronger than what they use in Japan. I didn't bother buying a converter, I just don't increase the heat past the first or second setting, and that's more than enough. I've had this since 2021, and it's still working great. Highly recommend!

コタツの温度調節がイマイチで購入　使いやすい、温度調節も細かくできて良かった

I bought this to attach to a table I modified into a Kotatsu and hooked it up to the PowerBright 500 Watts Japanese Voltage Transformer, and it's worked fantastic! There was a shipping hiccup and they sent me a new one right away, and it was super easy to install. I use it all the time and this is the second year I've had it, no issues whatsoever! It gets very warm so I usually don't leave it at the highest heat setting, but I've never been unhappy with the temperature or amount of control; it heats up and cools off quickly when I adjust the remote. My table is about 3ftx4ft with a comforter and a tabletop that fits on top, and it heats up that space within 5-10 minutes even in winter. I'd definitely recommend this product!
