Tokyocube is a very cool online lifestyle magazine targeting people interested in “fresh and fun online information on the ever-more fashionable Japanese lifestyle”. On there I found another great article on nutrition content and calories in individual nigiri sushi pieces and makis that might be of interest:

Tai - Sea Bream - 43.4Kcal
Nutrition: High-quality protein and vitamin B. It is very good for reducing high blood pressure. Although the taste of Tai is quite simple, it contains many flavourful ingredients such as glutaminic acid and inosinic acid, which create the unique rich taste.

Salmon - Salmon - 55.7Kcal
Nutrition: Well-balanced ingredients with protein, lipid, vitamins A, B, D, and minerals. It is particularly beneficial for people who suffer from dizziness and low blood pressure. As it is well known with raw salmon, it has a much stronger flavour compared to when it is cooked.

Anago - Conger Eel - 61.9Kcal
Nutrition: Protein, and plentiful in vitamins A and E, particularly beneficial for the skin. Although it is relatively high in calories, the taste still remains very refined and simple. Anago is either boiled or broiled and a special sauce consisting of soup stock, soy sauce and sugar is put on top.

Kazunoko - Herring Roe - 40.2Kcal
Nutrition: DHA, EPA, protein and rich in vitamin E. It reduces high cholesterol and encourages good blood circulation. Kazunoko is made of herring eggs which have been preserved in salt. It has a slightly crispy texture making for a satisfying sensation on the teeth.

Akagai - Ark Shell - 39.0Kcal
Nutrition: High in vitamin B, taurine and calcium. It decreases cholesterol and is good for aiding the recovery of fatigue. Akagai consists of the meat from inside of the Ark shell and is wrapped on top of rice. It has quite a simple, but also unique, taste and is nice and crunchy to eat

Toro - Fatty Tuna - 70.3Kcal
Nutrition: DHA, EPA and good for preventing geriatric diseases. This ‘Fatty Tuna’ is taken from part of the belly of the king Tuna, the biggest of them all. The distinct taste of Toro is similar to that of a high-quality steak, and it is regarded as the most valuable of all Sushi.

Maguro - Tuna - 57.1Kcal
Nutrition: Essential amino acids, vitamin B and iron. Maguro is produced from part of the red flesh in Tuna, which is far less fatty than Toro and is extremely healthy. Although the price is much cheaper than Toro, the taste is simple and light, making this a very popular dish.

Tamago - Sweet Egg Custard - 59.7Kcal
Nutrition: High-quality protein food and minerals. It consists of a traditional Japanese thick omelette on top with rice underneath and wrapped in seaweed. The slightly sweet taste of Tamago may remind you more of the taste of a dessert than a main course.

Kappamaki - Cucumber Sushi Roll - 17.2Kcal
Kappamaki is a type of sushi roll, very similar to Futomaki. It consists of vinegared rice rolled in a sheet of seaweed, with a stick of cucumber in the middle. Kappamaki is extremely low in calories, making it an excellent and popular choice for dieting.

Aji - Horse Mackerel - 60Kcal
Nutrition: DHA, calcium and taurine. Aji is typically very reasonably priced, and has an excellent balanced flavour to it making it a real favourite in Japan. To enhance the flavours, it would be recommended to eat with either a piece of ginger or chives.
