Jade Green Onion Beef Rice and Egg Mortar Innovation

This onigiri had the nice surprise of a soft-boiled egg in the middle. It tasted great, but I can't help wondering how it got from the factory to the shop unharmed. 148 yen from the trusty Family Mart up the road. The translator on dictionary.com told me it was called 'jade green onion beef rice and egg mortar innovation'.

Tarako Onigiri

This tarako onigiri was a little dry but very tasty. Tarako is the salted roe of the Alaskan Pollock - a kind of cod. 125yen from Family Mart.

Ikura onigiri

A nice version of ikura onigiri sofly wrapped in nori. In addition to the salmon roe, this one also has some other kind of grain thrown in for texture - barley perhaps? From Family Mart

Three Chambers of Flavour

A massive three chambered onigiri. It appeared to contain minced cured salmon, pickled plum and some marinated seaweed. It came with a few pieces of pickled daikon. Bought at near Kyobashi station.

Mentaiko Onigiri

Mentaiko onigiri. Fishy, spicy and delicious. 135yen from Family Mart. 

I've eaten and enjoyed this many times but never really understood exactly what is was... Mentaiko is the marinated roe of the Pollock.... Originally Korean, brought to Japan in the heady days folling the Russo-Japanese War then Japanafied by Kawahara Toshio in the 1950s... Thanks wikipedia!
