The Story of the Otomobori – The Manmade River The central axis of urban Sapporo
Infrastructure of the Otomobori in 1866 (Keio 2)
ー The spirit of Kametaro and the prosperity of Sapporoki ー

It has been common belief that the development of Sapporo is thought to have begun in 1869 (Meiji 2) when the pioneering judge, Yoshitake Shima, began construction of the Sapporo Government Office. However, this is not the case.The Otomobori, to which Yoshitake Shima utilized the north-south axis of Sapporo as an island, was excavated by Kametaro Otomo in 1866 (Keio 2) as a drainage ditch for the directly managed farms of the Hakodate Magistrate.The infrastructure during the end of the Edo period later contributed to the production of Sapporo-grown onions called “Sapporoki”.If you trace the remains of the Otomobori, you can see the course of the historic river and encounter an old Sapporo through numerous cultural items, ancient temples, and the Sapporo Village History Memorial Hall.

Otomobori, which was built by an apprentice of Kinjiro Ninomiya.

The name “Otomobori” comes from Kametaro Otomo, a government official in the shogunate.Kametaro was a disciple of Sontoku Ninomiya, and after he learned about the “Hotoku Shihou” rural revival policy, he went to present-day Hokkaido, which was then called “Ezo” at that time.The Hakodate Magistrate later ordered the establishment of a cultivated land on the directly-operated farm called “Otesakuba” and began excavating a drainage channel in the current Higashi-ku are of Sapporo city in 1866 (Keio 2).The water source for this was a branch of the Toyohira River, which flowed northward from around West 3 to North 6, and then extended northeast to merge with the Fushiko Satsunai River. The construction work, which covered about 4 km, was known as the “Million Ryo Mega Project”.

In 1869 (Meiji 2), when Yoshitake Shima, began the construction of the Sapporo Government Office, the Otomobori, a legacy of the shogunate, already existed there.Afterward, the Otomobori played a significant role as a shipping route for transporting goods.

Sapporo city was later divided into a grid pattern, while the Otomobori was renamed as the Sosei River.

Michitoshi Iwamura, the successor of Yoshitake Shima, first divided the city into a northern administrative district and a southern commercial and residential district, with the wide green space of Shiribeshi Street (now Odori Park) serving as the border. He divided the city into east and west by creating the Otomobori.The grid patterned streets, with each block measuring about 109 meters on each side, became the foundation of Sapporo.

Development began during the end of the Edo period. The areas where the Otesakuba cultivated lands were established were called Sapporo-mura and Moto-mura.The layout of that area still remains today. It is possible to see traces of the Otesakuba cultivated land around the houses and on maps of that district.Interestingly, the road leading from North 6 to the Sapporo Village History Memorial Hall, which used to be the residence of the Otesakuba officials, is a diagonal road, which is very rare in Sapporo’s grid-pattern layout.

In 1870 (Meiji 3), the Teraobori was dug from Kita 6-jo, where the Otomobori was located, to the confluence point of the former Kotoni River to the north. The Yoshidabori was also excavated from West 3 to West 6, extending the Otomobori north and south.In 1871 (Meiji 4) Michitoshi Iwamura named the bridge over the Otomo Canal the “Sosei Bridge”. As a result, in 1874 (Meiji 7), the Otomo Canal was renamed the Sosei River.

Traces of the Otomobori can still be seen in residential areas.

Most of the Otomobori have been filled in now, but parts of it remain as the Sosei River. In Higashi Ward, there are also streets that appear to be remnants of the Otomobori, such as the diagonal block at North 11 West 11.Why not take a walk through the residential areas and explore the remnants of the old Otomobori with a historic map in hand?

Sapporoki is a type of onion produced in Sapporo and exported globally.

Farmers learned onion cultivation in Sapporo Village under the guidance of Dr. Brooks and later succeeded to grow the western vegetable in 1880.The onion variety called Sapporoki was highly valued as a food source for miners and people on board ships. At the time, it became a staple export to Russia.

The lion masks, called Shishimai, are dedicated to the Okadama Shrine for the bountiful harvests and has since become the first intangible cultural asset of Sapporo City.

The neighborhood around diagonal street is dotted with various attractions, such as the Sapporo Village Local Memorial Hall, which exhibits materials related to Otesakuba and Sapporoki, the Honryuji Temple, which is home to the Myoken-do Hall associated with Kametaro Otomo, and the Daikakuji Temple, which boasts the largest gate in Hokkaido.Relive the vestiges of Sapporo’s pioneer era since the end of the Edo period.

Sapporoki was exported across the globe.

Around 1880 (Meiji 13), Sapporo Village succeeded in cultivating onions, a Western vegetable, with the guidance of Dr. Brooks.Mass exports of the Sapporoki onion soon followed not only down to Honshu, but also to Russia and Southeast Asia.The Sapporo Village History Memorial Hall displays a passport from a visit to Russia, conveying the passionate feelings of the local citizens at that time.

    It is said that the irrigation ditch excavated by Kametaro Otomo in the late Edo period for agricultural and domestic water supply was just the beginning.
    Afterward, through changes in usage methods and routes, the channel became the river it is today. The original name of Otomobori was also renamed to Sosei River in 1874 (Meiji 7).
