Hakata Bay in 1274: Tidal Flats, Hills and a Coast Before the Stone Wall

A coast without the later stone wall was not a coast without people preparing to defend it. Fukuoka City Museum explains that, before the Bun’ei invasion, the Kamakura shogunate ordered retainers with holdings in Kyushu to undertake defense there. They joined warrior groups already based in the region.

Preparing for an army coming across the sea required more than an individual carrying weapons. There had to be arrangements for deciding who would go where and for moving people. Commands from the shogunate and relationships with land formed part of the background to warriors appearing on the coast.

Attention to that system gives greater depth to a party of travelers shown in the scrolls. Their presence on the battlefield was itself connected with orders and regional relationships. The image of a warrior arriving can therefore be placed within an organization of service and preparation.

The existence of an order does not reveal the complete deployment on the day of battle. This account takes the requirement for defense before the invasion as a starting point, then follows the places and movements that enter the record. It does not fill the gaps with a complete army plan.

Torikai remains a name in modern Fukuoka. From the landscape depicted in the scrolls, Fukuoka City Museum reads an inlet reaching deeply into the area now occupied by Ōhori Park, with extensive tidal flats. The former waterside needs to be considered beneath today’s park and streets.

If the boundary between sea and land reached farther inland, the connections along which people and horses moved would look different from those on a modern map. Water in the scrolls is therefore more than background decoration. It supplies information for considering the terrain represented in a scene.

A painted scene cannot yield measured road widths or travel speeds. The account instead follows the museum’s explanation, bringing depicted scenes and place names together to consider the relationship between water and land. The image provides clues, without becoming a surveyed plan of the battlefield.

Following the waterside gives the battlefield depth: movement along a shore could meet movement leading into the land. Torikai’s tidal flats offer a point of entry into that relationship. They help reveal why present-day streets alone are an insufficient guide to the spaces in which the fighting took place.

The party accompanying Takezaki Suenaga, a warrior from Higo and the scrolls’ central figure, traveled before reaching the battlefield. Fukuoka City Museum explains a sequence in the scrolls from the camp at Hakozaki through Hakata, Sumiyoshi and Akasaka to fighting on the tidal flats at Torikai.

Familiar place names can invite a reader to draw one firm line on a modern map. Komatsubara, which appears along the way, has not been securely identified in the explanation. Reading this journey requires preserving both the places that can be identified and the point that remains uncertain.

Suenaga’s movement presents Hakata Bay in 1274 as a connected series of places. The warriors did not simply appear on the beach: the story takes them out of a camp and through settlements and paths toward the fighting. Movement across the land is part of what the scrolls convey.

Following the party brings the organization of defense into contact with actual terrain. Yet the route narrated from Suenaga’s side has a different scope from a complete map of both armies’ actions. It is useful precisely when the particular perspective and the unidentified places remain visible.

Suenaga’s activities after the fighting also concerned land. The Cultural Heritage Online explanation states that he received Kaitō-gō as a reward for service in the Bun’ei invasion and entered the holding in the first month of 1276. Military service thus connected with the basis of his subsequent life.

His donation document and later written provisions concern shrines, a temple and the management of the holding. This is a different kind of record from the depiction of military achievements in the scrolls. It reveals aspects of a warrior who had received land and continued to act within a local community.

Rather than attempting a complete account of the reward negotiations, this chapter notes that records continue outside the battlefield story. Establishing the scope of a particular document helps distinguish the scroll’s fighting scenes from papers concerning land. Neither kind of evidence should automatically be made to do the other’s work.

The person who traveled through the Hakata Bay battlefield continued living within regional relationships afterward. Reading the figure engaged in fighting alongside the figure leaving records about land and people places the effort to preserve his service within a longer stretch of time. The battle was not his whole subsequent life.

In Kenji 2, or 1276, construction of the stone defenses proceeded along Hakata Bay, two years after the Bun’ei invasion. The prefectural cultural-property explanation describes a coastal span of about twenty kilometers, from Imazu to Kashii, with work divided among the nine historical provinces of Kyushu.

One project for a long defensive line consisted of several assigned sections. Differences in foundations and methods of laying stones remain recognizable from place to place. The structures gathered under one name therefore also preserve differences in the construction undertaken in their separate sections.

Fukuoka City’s Imazu explanation describes farmers as the workforce and says the defenses are thought to have been completed in about half a year. Besides assembling warriors on the coast, preparation involved the work of carrying and stacking stone, extending the defense effort into the lives of people in the region.

The figure of about twenty kilometers describes the extent of the original construction. It does not mean that every part survives today in the same form. Moving from the historical building project to the visible remains requires distinguishing the original scale from the portions preserved or restored.

Some places where the defenses can be seen today were preserved and presented after archaeological investigation. Parts had been buried in sand or damaged in later periods. Fukuoka City Museum describes the sequence of modern investigations and the substantial excavations undertaken between 1968 and 1971.

At Imazu, the city explains that about two hundred meters have been restored and presented. The visible stonework thus carries a history extending from medieval construction through modern investigation and conservation. Its appearance in a photograph or at a site needs to be read together with that history.

Attention can then return from the stonework to Torikai’s tidal flats, Sohara’s hill and the path from Hakozaki. Names surviving in the city offer small points of entry into thinking about a lost waterside and battlefield. They provide clues without preserving the whole medieval landscape unchanged.

Following Hakata Bay in 1274 means resisting the addition of a later long wall to the first battlefield. The scrolls and place names provide one set of clues; the subsequent construction belongs to a later stage. Looking carefully at the boundary of sea and land connects the fighting with the work of those preparing for another arrival.
