Former 7th Division Headquarters Site (Hokuchin Memorial Museum)

The former 7th Division Headquarters site (旭川第七師団司令部跡) in Asahikawa, Hokkaido, marks the home base of one of the Imperial Japanese Army's most storied formations — the "Hokuchin Butai" (北鎮部隊, Pacifier of the North), also known as the "Bear Division." Today, the adjacent Hokuchin Memorial Museum (北鎮記念館) serves as the primary repository of the division's history, operated by the Japan Ground Self-Defense Force (JGSDF) 2nd Division.

Origins: From Tondenhei to the 7th Division (1875–1896)

The roots of the 7th Division lie in the Tondenhei (屯田兵, soldier-farmer) system established in 1875 to colonize and defend Hokkaido. These military settlers, many recruited from former samurai families dispossessed after the Meiji Restoration, simultaneously cleared farmland and stood ready as a militia against potential Russian encroachment from the north. By the 1880s, the Tondenhei units had been consolidated into a more formal military structure.

On 12 May 1896, following the First Sino-Japanese War, the Tondenhei were reorganized as the 7th Division (第七師団), with a provisional headquarters at the Tondenhei headquarters in Tsukisamu, near Sapporo. The headquarters moved to Chikabumi on the outskirts of Asahikawa in October 1901 and into a purpose-built headquarters building there in October 1902. The division was responsible for the defense of all Hokkaido and drew its recruits from four regimental districts: Sapporo, Hakodate, Asahikawa, and Kushiro.

Russo-Japanese War (1904–1905)

The 7th Division's first major test came during the Russo-Japanese War. Under the command of the 3rd Army led by General Nogi Maresuke, the division participated in the brutal Siege of Port Arthur (August 1904 – January 1905), one of the bloodiest engagements in modern warfare up to that point. The division subsequently fought in the decisive Battle of Mukden (February–March 1905). Division commander Lieutenant General Ōsako Naotoshi led the 7th Division through these campaigns, and a calligraphy piece presented to him by General Nogi after the triumphant return to Asahikawa remains one of the museum's treasured exhibits.

Interwar Period and Manchuria

During the interwar years, the 7th Division maintained its role as the guardian of Japan's northern frontier. With the Manchurian Incident of 1931 and subsequent Japanese expansion into Manchuria, elements of the 7th Division were deployed to the Asian mainland to support occupation operations.

The Nomonhan Incident / Battles of Khalkhin Gol (1939)

The defining interwar engagement for the 7th Division was the Nomonhan Incident (ノモンハン事件), known internationally as the Battles of Khalkhin Gol, fought on the Manchuria-Mongolia border from May to September 1939. The 26th Infantry Regiment of the 7th Division, under Colonel Sumi Shin'ichirō, was thrown into battle against overwhelming Soviet mechanized forces commanded by Georgy Zhukov.

Facing Soviet tanks with virtually no anti-armour weapons, Sumi's troops resorted to desperate measures — attacking tanks with Molotov cocktails (ガソリン瓶) and improvised explosives at close range. The regiment reportedly destroyed 83 enemy tanks through these suicidal tactics, earning legendary status. However, casualties were devastating. Colonel Sumi himself was later relieved of command for refusing what he considered reckless orders that would have further squandered his men's lives — an act of moral courage that remains controversial in Japanese military history. The Nomonhan Incident profoundly shocked the Japanese military establishment and contributed to the strategic decision to advance southward into Southeast Asia rather than northward against the Soviet Union.

The Battle of Attu — First Gyokusai (May 1943)

The most tragic chapter in the 7th Division's history unfolded on Attu Island in the Aleutian chain. In June 1942, as a diversionary operation during the Battle of Midway, Japanese forces occupied the remote islands of Attu and Kiska in the western Aleutians. Attu was seized by the North Sea Detachment (北海支隊, Hokkai Shitai), a force of about 1,150 men formed by the 7th Division. That detachment was later moved to Kiska, and from late 1942 Attu was held by a new garrison built around infantry from the North Kuril fortress — the 2nd Sector Unit of the North Seas Garrison (北海守備隊).

On 11 May 1943, the US Army's 7th Infantry Division landed on Attu to recapture the island. After fierce fighting in the fog-shrouded, mountainous terrain, the approximately 2,600 Japanese defenders were pushed into a final pocket. On 29 May 1943, Colonel Yamasaki Yasuyo led the surviving garrison in a desperate banzai charge — one of the largest of the Pacific War. Nearly the entire garrison was annihilated; between 16 and 29 Japanese soldiers, depending on the source, were captured alive.

The Battle of Attu marked the first time the Japanese government used the term "gyokusai" (玉砕, literally "shattering like a jewel" — honorable death rather than surrender) in an official communiqué, establishing a grim precedent that would be repeated on island after island throughout the Pacific War. Imperial General Headquarters had considered reinforcing Attu with troops drawn from the 7th Division, but the plan was abandoned and the garrison was left without relief.

Reorganization and End of War (1943–1945)

Apart from detachments such as the Ichiki Detachment sent to Guadalcanal, the main body of the 7th Division stayed in Hokkaido. In February 1944 its depot division became the basis for the new 77th Division, and in March 1944 the 7th Division headquarters moved from Asahikawa to Obihiro to defend eastern Hokkaido, where it remained until the war's end in August 1945.

The Hokuchin Memorial Museum (1963–Present)

The story of the museum began in 1962 when Wada Moriya (和田盛哉), commander of the JGSDF 2nd Division, was presented with a sabre used by Cossack cavalry in the Russo-Japanese War. This sparked the initiative to create a permanent repository for the military heritage of northern Japan. The first Hokuchin Memorial Hall opened in August 1963.

The current museum building, the second-largest JGSDF public relations facility in Japan (after the JGSDF Public Relations Center in Saitama Prefecture), is located adjacent to Camp Asahikawa (旭川駐屯地). Uniquely, visitors can enter the museum without passing through the military camp gates. The museum displays approximately 2,500 items spanning the Tondenhei era through the 7th Division's campaigns to the modern JGSDF 2nd Division.

Notable exhibits include: the Nogi-to-Ōsako calligraphy from the Russo-Japanese War; Nomonhan Incident battle artefacts; personal effects of soldiers killed at Attu; the Rising Sun battle flag (旭日旗) carried by units in various campaigns; and the Gate Piers of the 7th Division Headquarters Building, originally constructed in 1902 and relocated to the museum grounds in November 2015. In 2006, a set of confidential 7th Division documents held by the museum was designated a cultural property of Asahikawa City.

Admission is free, and the museum serves as both a memorial to the fallen and an educational resource about the military history of Hokkaido and northern Japan.
