Tonburi: Where to Eat, Prices & Opening Hours (Akita)

Tonburi is a specialty of Odate in Akita, made from the ripe seeds of the broom cypress, which are harvested, dried, heated, rinsed to remove the skins, and carefully processed. Production is especially active in the former Hinai area, and cultivation and processing take place only in Odate City. Glossy black and one to two millimeters across with a popping texture, its appearance earns it the nicknames caviar of the fields and herring roe of the land.

Highlights

Its greatest appeal is the burst-in-the-mouth texture. Because it barely asserts a flavor of its own, it pairs well with sticky foods and a wide range of dishes such as grated yam, natto, tofu, vinegared dishes, and vinegar-miso salads. It is valued as an accent of color and texture. Each household has its own ways too, such as combining it with tuna or vegetables.

Enjoying the Seasons

Harvest and processing take place in autumn. Ripe seeds are gathered from September to early October and finished through a labor-intensive process, washed until the water runs clear. Once processed it keeps well, so it can be enjoyed year-round even after the season passes.

Practical Travel Notes

Odate City, including the Hinai area, is the sole production area. From JR Odate Station, bottled or packaged tonburi is available at farm stands, roadside stations, and souvenir shops. It keeps well and is light and compact, making it a good souvenir. At local restaurants it may be served as a garnish for grated yam or soba. Being mild and nearly odorless, it works broadly as an accent of color and texture in cooking.

A Quick Tip

Mix it into grated yam over rice for a duet of silky smoothness and popping texture.

Practical Information for Your Visit

• Production area and protection: On May 26 in Heisei 29 (2017) it was registered as Geographical Indication (GI) No. 32, "Odate Tonburi," with Odate City in Akita Prefecture as the production area. On March 28 in Reiwa 7 (2025), the "tonburi production techniques of Odate" became a nationally registered intangible folk cultural property (the first in Akita Prefecture).
• Public facility where you can buy it: Roadside Station Hinai "Totto-kan" (93-11 Shin-Ozutsumishita, Ogita, Hinai-machi, Odate City / 0186-50-7700). It is open 9:00-17:00 from April to December and 9:00-16:00 from January to March, and is closed over the New Year period (December 31 to January 2).
• Points to note: According to JA Akita Kita, the citric acid treatment used in processing gives tonburi a faint tartness, and mixing it with salty seasonings draws out moisture. It is best to dress it just before eating. The fresh type keeps for about two weeks under refrigeration, and the bottled type for about nine months at room temperature.

* Opening hours and prices at individual shops vary from shop to shop.
