I was at a business dinner in Tokyo about a year ago. They served us these harmless looking tofu cubes on a small plate with just a bit of soy on top. It was absolutely the worst thing I ever tasted. I had to put my hand over my mouth to keep from barfing - which would have made quite an impression on our business partners! I am very adventurous with food. I'll try anything. These fermented tofu things are at the top of my very short "do not eat" list.
