The Yashima and Chokai areas, located at the foot of Mount Chokai, have long relied on agriculture. However, because of the high altitude and heavy snow, growing rice was extremely difficult. The region frequently suffered from severe cold weather and poor harvests. Even after the Meiji period, crop yields sometimes dropped to less than half of a normal year. To adapt to these harsh conditions, local people grew buckwheat (soba) and other field crops.
To survive the frequent food shortages, locals had to be creative. They found ways to get starch from wild plants like bracken (warabi) and kudzu, and used horse chestnuts and wild grape leaves for food. Matsukawa-mochi, made from pine bark, also originated from this traditional wisdom as an emergency food during severe crop failures.
Historically, it is said that people in the Chokai and Yashima areas started making Matsukawa-mochi during the Great Tenmei Famine in the Edo period. Another famous theory suggests that it was originally invented as a survival food to prepare for military sieges (starvation tactics) during wartime. What began as a desperate measure for survival is still passed down today as a unique food culture.
Matsukawa-mochi is a traditional sweet found in the Chokai and Yashima areas. It is famous for its beautiful reddish-purple color, which comes from kneading the inner bark of red pine (akamatsu) into the mochi. Although it was originally an emergency food, it is often eaten at celebratory events today. This is because the pine tree represents a long life, and its green color symbolizes good fortune.
Making this mochi requires a lot of time and effort. From June to August, locals harvest the inner bark of red pine trees and sun-dry it for about a week. To remove the bitterness, the bark is carefully boiled with baking soda for eight hours until the water turns purple. After that, it is beaten with a hatchet until soft and then pounded together with freshly steamed glutinous rice.
Inside the mochi is handmade, smooth red bean paste (koshian). It actually has no pine odor and offers a gentle, faint sweetness. Because of the complex making process, it is a precious item. Today, it is sold for about 100 yen at local farmers' markets (Michi-no-Eki), but it is so popular that it often sells out by the morning.

I am from the Honjo area of Yurihonjo City. I often saw Matsukawa-mochi sold in three-piece packs at my local supermarket. It is especially popular among the elderly and often sells out by morning.
My grandfather loved eating it, and he shared some with me several times. At first, I was worried about the pine resin flavor, but it has no strange taste or smell. The moist, chewy texture of the dough, combined with the gentle sweetness of the smooth red bean paste, is absolutely delicious. It is a very special flavor that connects me to my hometown.
