The Great North Road, or Nakasendō, is the inland axis Toranaga privately chooses for the main thrust of his coming campaign. Its importance lies not in a battle already fought, but in the way its position near the capital shapes his plan: he means to approach by this road rather than the coastal Tokaido, while concealing which route he will ultimately take.

Setting and route

Toranaga considers the battle likely to be fought near the capital, somewhere northward around Gifu, Ogaki, or Hashima, along the Great North Road. He also weighs a more specific possibility: the mountains near Sekigahara, where the road turns south toward the capital. These are prospective battle locations in his planning, not a battle whose course the passage narrates.

The road is set against the Tokaido, the coastal route. Toranaga’s distinction between the two is strategic: the inland road offers the axis for his main advance, while the existence of a competing route gives him room to obscure his intentions. The geography becomes part of the campaign before armies meet.

Toranaga’s choice

Toranaga believes that remaining behind his mountains could keep him safe for years. He nevertheless sees an opening: Ishido’s vulnerable position, in his assessment, makes the moment worth risking that security. He therefore plans to send his main force along the Great North Road, rather than the Tokaido, toward a battle near the capital.

The route choice is not to be disclosed as a settled intention. Toranaga plans to pretend to change his mind repeatedly, keeping the direction of the advance uncertain. The road thus serves both as a line of movement and as part of a deception: an apparent choice can be revised, and an enemy cannot safely treat any announced route as final.

The projected campaign

Toranaga expects his brother, Zataki, to ride with him. He also anticipates that Kiyama may change sides during the battle and attack his rival, Onoshi. In Toranaga’s projected sequence, that change would signal the guns to advance; his forces would then roll up the sides of the opposing armies. The Great North Road is the intended approach to this larger maneuver, not an isolated geographical detail.

These expectations remain conditional. Toranaga thinks Kiyama may turn, and his plan depends on what that shift would signal; the passage presents the campaign as a design still being held in the mind, not as an outcome already secured.

Narrative significance

The Great North Road concentrates the contrast between safety and opportunity in Toranaga’s planning. The mountains promise protection, but the road points toward a contest for power near the capital. Choosing the inland approach while feigning uncertainty over the route shows how military movement and political misdirection work together in his strategy. At this point, the road marks the place where a future decision may become a battle, rather than a battlefield the narrative has yet shown.
