In Northern Japan, mackerel is a popular fish, but there is no culture of consuming it as sashimi. The present study aimed to establish a handling method for frozen mackerel that would make full use of freezing technology, give root to a culture of consuming mackerel as sashimi, and improve the value of mackerel. The influence on the freshness of raw materials from being kept in frozen storage conditions over a period of time on K-value sup(1)) and rate of inosinic acid was investigated. The proper thawing method was also examined. As a result, it was revealed that eating mackerel in a sashimi state was possible after defrosting at low temperatures in running water, if highly fresh material was frozen quickly, kept at -30℃ and stored less than 10 months. It might not be easy if only established techniques are used, but we think that the flavor of the Hachinohe mackerel is appealing enough to enable a change in the culture.
