There are different models Ultra 3 for cellular antenna(s) per region, but Japan and Spain are in the same “rest of the world” region for this.

The other regions are US and Canada, China Mainland, Hong Kong and Macao, for Apple Watches in general. For the Ultra 3, only China Mainland is separate.

Apple Watch - Carriers - Apple

Note that warranty and other service is only available in the country where the device was purchased. If you need that, you’d have to bring it back to Japan. For me, that alone would be reason enough to buy locally.
