The bed was the hardest bed I have ever seen. It was like sleeping on a desk. Honestly, I could feel springs as if it was a box spring covered by a mattress pad. I'm a heavy guy, and this bed didn't even react to my lying on it.
The pillow was very firm, the Japanese type of pillow with hard beads or rocks on one side. The duvet was not fluffy down and it didn't "breathe" so it's either too hot with it on or too cold with it off (this was winter). I didn't turn on the heat because it was noisy and smelled like cigarettes.
The breakfast had the usual buffet you find in Japan: no variety of bread, no cheese at all, not much meat except little sausages and bacon. The food was laid out in heating trays but there was no heat, so the cute egg omelets were cold, the sausages were cold, the bacon was cold. To be fair, I went to breakfast an hour after it started, so the food might have been hot at 6:30 AM.
There's a large, free "sento" (Japanese bath) with separate rooms for men and women.
