Theories Behind the Name “Kujira Mochi”
The unusual name “Kujira Mochi” has several possible origins. One theory connects the name to its long shelf life. The characters 久持良餅 can be interpreted as meaning “a good mochi that lasts a long time,” reflecting its usefulness as a preserved food.
Another theory suggests that the confection was once made in a much larger form, with its shape compared to that of a whale. There is also a theory that the name came from its appearance: the contrasting white and dark layers were thought to resemble the cross-section of a whale’s skin and blubber.
There is no single universally accepted explanation for the name, making its history part of the fascination surrounding this traditional regional sweet.
Traditional Preparation and Distinctive Flavor
Kujira Mochi is traditionally made by mixing glutinous rice flour and non-glutinous rice flour with water. The mixture is spread into a mold or container, combined with ingredients such as sugar, sweet red bean paste, miso, or soy sauce, and then steamed in a traditional steamer.
Aomori-style Kujira Mochi is particularly known for the pleasant crunch of walnuts incorporated into the dough. Its sweetness is relatively mild, giving it a simple and satisfying flavor that is easy to enjoy without becoming overwhelming.
The texture is pleasantly chewy and substantial, while the traditional preparation gives the confection a handmade character. Rather than being an elaborate dessert, Kujira Mochi reflects the everyday wisdom and craftsmanship of local food culture.
Ajigasawa’s Kujira Mochi and the Kitamaebune Trade
The Kujira Mochi of Ajigasawa is traditionally associated with the Kitamaebune, merchant ships that traveled along the Sea of Japan between the Edo and Meiji periods. It is believed that a confectionery tradition from Kyoto was brought to the region through these maritime trade routes.
Historical documents from the period describe the method of making Kujira Mochi and introduce it as one of the confectionery traditions associated with Kyoto. Its refined taste was highly regarded at the time.
Ajigasawa once had several shops specializing in this confection. Today, Honpo Murakamiya, a confectionery shop founded during the Meiji period, continues to preserve the local tradition.
Asamushi Onsen’s Famous Souvenir Sweet
Kujira Mochi also became closely associated with Asamushi Onsen. After the Russo-Japanese War, wounded soldiers stayed in Asamushi for hot spring treatments, and the confection became popular as a souvenir.
Its practical qualities helped make it particularly suitable for travelers. It was inexpensive, easy to carry, and relatively resistant to spoilage, making it a convenient gift to take home after a stay at the hot spring resort.
By the Taisho period, Kujira Mochi had also been entered in food competitions and had become firmly established as one of the traditional specialties associated with Asamushi Onsen.
A Taste of Aomori’s Food Culture
Kujira Mochi is a regional sweet whose appeal lies in its simplicity rather than elaborate decoration. Its chewy texture, gentle sweetness, and walnuts offer a taste of the food culture that has developed alongside everyday life and travel in northern Japan.
When visiting Aomori, trying Kujira Mochi is a delicious way to discover a lesser-known local tradition. Enjoying this humble confection while learning about its history and the travelers who helped spread it provides an opportunity to experience a small but fascinating part of Aomori’s cultural heritage.
