The Takeda: Kai, and the Battle That Is Told Wrong

Kofu, Erin-ji, Kawanakajima, and a grave you can see one day a month

武田氏 · last checked 2026-10-26

Takeda Shingen ruled Kai province for thirty years and never built a castle.

He governed from a walled house on the valley floor at Tsutsujigasaki, on the principle — quoted ever since, in a poem that may or may not be his — that men are the castle, men are the walls. Whether he said it or not, the archaeology agrees with him: there is no keep in Kofu and there never was.

That is not a portrait of him. It is Utagawa Kuniyoshi, working in the 1840s, imagining a man who had been dead for two hundred and seventy years. It is on this page because it is honest about being an invention, which is more than can be said for the painting everyone else uses.

Part 1 — The house, not the castle

What survives at Tsutsujigasaki is the shape of the residence: the moats, the earth banks, the ground plan that archaeologists are still working through. A shrine was built over it in 1919 and the treasure hall holds the war fan.

Stand at the moat and the strategic argument makes itself. A castle on a hill announces a frontier. A fortified house in the middle of a valley says the province is already held.

Part 2 — Kawanakajima, five times

Between 1553 and 1564 Shingen fought Uesugi Kenshin on the same river plain in Nagano five times. The fourth, in 1561, was the only one that was properly a battle, and it is the one every telling means.

The version that gets repeated — Kenshin riding into Shingen’s command post and striking at him while Shingen parries with his iron war fan — comes from the Koyo Gunkan, a seventeenth-century compilation written long after both men were dead. It is marvellous and it is not evidence. What the contemporary record supports is a very large, very costly engagement in heavy morning mist that settled nothing: both sides claimed it, and the border did not move.

Part 3 — The three quiet years

Shingen died in 1573, on campaign, aged fifty-two. By his instruction his death was concealed for three years while the house consolidated — and this is where the sites get complicated, because a man whose death is secret cannot have a public funeral.

Read the caution above before you plan the day. The grave at Erin-ji is open on the twelfth of the month, Shingen’s monthly death anniversary, and not otherwise. The garden is open daily and is a Muso Kokushi design of the first rank. But if you are going for the tomb, there is exactly one date a month on which that works, and almost nothing written in English says so.

Nine years after Shingen died, Oda Nobunaga’s army burned Erin-ji with the abbot and his monks inside it, for sheltering Takeda retainers. The temple you walk into is what was built afterwards.

Part 4 — Fact and legend

The portrait: doubted. The famous painting — heavy-set, in a red robe, held at Jimyo-in on Koyasan — is no longer confidently identified as Shingen at all. A copy of it is now taken to show a member of the Noto Hatakeyama house, and specialists have been arguing about the original for years. No certain likeness of him survives. This is the third portrait on this site to have come loose from its name, after the Jingo-ji “Yoritomo” and the mounted warrior called Takauji; it is worth knowing how common this is.

The duel at Kawanakajima: retold. See above. A seventeenth-century book, not a contemporary one.

“Men are the castle”: retold, probably. The poem is attributed to Shingen and appears in later collections. The policy, though, is documented in the ground — he really did rule without a keep.

The hidden death: documented. The three-year concealment is attested, and it explains why Kai has a grave that opens once a month, a second claimed grave in a Kofu suburb, and no agreement about which is real.

Before you go

Erin-ji is open 8:30 to 16:30 all year, ten minutes by bus from Enzan. The temple and garden are one ticket and the treasure hall another, around 500 yen each — published figures disagree and the fee has been revised, so take that as an estimate rather than a promise. The twelfth of the month is the date that matters.

Takeda Shrine is at the end of the bus line north from Kofu station, about ten minutes, and the grounds are free. Kawanakajima is not in Yamanashi at all — it is outside Nagano city, two hours away, and makes sense as part of a trip toward the Sanada country rather than as a day out of Kofu.

Yumura is six minutes by car from Kofu station, which makes it the unusual case of an onsen close enough to a city to be practical and still not walkable. Six inns are bookable in English; the two worth the money are marked below.
