The thought of eating eel can be off-putting, yet the super-fragrant, umami-tasting, velvety-textured delicacy is one of Japan’s prized foods. A best bet for dining like a true Tokyoite is to include an unagi (freshwater eel) meal at one of Tokyo’s top unagi restaurants serving only the one delicacy. The first Japanese character in the Japanese word for unagi (う) resembles the meter-long fish, and most unagi places enthusiastically employ imaginative ways to display their specialty on signs outside the restaurant. The fish can be expensive, depending on quality, and is highly prized for its preparation, taste and nutrition, being high in Vitamin A, B-complex, protein and calcium.
