The Ainu called salmon “shipe” from the original phrase “shi-e-pe” which translates into “the real thing we eat”, meaning “our staple food”.
Other foods include deer, bear, wild fruits and berries, millet, wild onions, wild potatoes and other plants.
According to Masami Iwasaki-Goodman, food culture is learned from birth and developed as children grow up eating what their families eat and preparing it, treating it, and valuing it as their families do. “Along with food habits, children also learn the attitudes and values associated with food items and their preparation through interactions with family members and friends.” (Iwasaki-Goodman) Lasting ties are formed in kitchens and around the table. Tastes and traditions are passed from generation to generation, all through food. When those traditions are taken away, so are the ties that they bring. (Iwasaki-Goodman,)
The diet shift from Ainu food – salmon, deer and wild vegetables with grains – to Japanese food, such as white rice, pork, chicken and vegetables, did not cause serious negative effects on the health of Ainu people.
However, although the diet change had an insignificant impact on the health and nutrition of Ainu people, it had a serious cultural impact in the minds of both Ainu and non-Ainu people in Saru River region. Mainstream Japanese culture dominated the community, affecting local people’s views regarding every aspect of life. (Iwasaki-Goodman, Masami.)
