The only hotel we stayed in in which there was no breakfast buffet was the Hotel Edit Yokohama, which was too hip to have such an offering. Anyway, here is my last buffet breakfast in Japan. From top to bottom, left to right:
Salami
Chawanmushi-like item
Goya (bitter melon) Chanpuru
Natto (still in packaging)
Tofuyo (fermented bean curd)
Some sort of broiled fish
Two sausages
Japanese style bacon
Scrambled egg
