What are the specifications of Japanese quilts?

If it is a single bed, the pillow is very small. In the past, domestic pillowcases were basically large, but there were a few small sheets. It doesn't matter. I only brought two sets of domestic ordinary single bed products, except the pillowcase, which was basically usable. Just buy an ordinary single bed on the market.

The pillow seems to be only 40*70.
