City · The Kamakura house and its housemen · as at first light, 1 January 1200

Kamakura

Kamakura is a town twenty years old.

Yoritomo entered the valley in the tenth month of 1180 on the advice of the Chiba and the Miura: three hills, one open front at the sea beach of Yuigahama, and narrow passes that a few men can hold. He built his mansion at Ōkura (the Ōkura gosho) east of the centre, moved the Hachiman shrine to the hill, and in 1182, while Masako was carrying Yoriie, laid out the straight avenue (Wakamiya Ōji) from the shrine to the sea (recalled). Round the mansion stand the offices of the regime: the Mandokoro under Ōe no Hiromoto, the Monchūjo under Miyoshi Yasunobu and the Saburai-dokoro under Wada Yoshimori.

Every great houseman keeps a house in the city for the guard duty he owes. Tsurugaoka, Shōchōju-in (1184), Yōfukuji (1189 to 1192), Yoritomo's Hokkedō and Egara Tenjin stand; Jufukuji does not yet exist: Masako founds it in the course of 1200 (the likely course, month not pinned; Jufukuji (to be founded in 1200)). There are no walls: the hills and the sea are the wall. The Great Buddha (1252), Kenchōji (1253), the cut passes and the Rokuhara-style Kyoto post (1221) do not yet exist.

Lord in 1200

Minamoto no Yoriie, with the Thirteen sitting beside him; the Saburai-dokoro keeps the peace in the city

Charter

None: a seat of government and not a chartered town.

Council

The Mandokoro (Ōe no Hiromoto), the Monchūjo (Miyoshi Yasunobu) and the Saburai-dokoro (bettō Wada Yoshimori) under the Thirteen; the city has no council of its own.

Communities

Housemen and their households; the court-trained officials from Kyoto (Ōe, Miyoshi, Nakahara, Nikaidō); monks; carvers and craftsmen; boatmen at Yuigahama. Population: no figure.

Fairs and markets

None known (the regulation of the markets of Kamakura belongs to 1213 and 1253, later).

Militia

The housemen's guard duty in Kamakura, ordered by the Saburai-dokoro; no numbers.

Walls and castle

No walls. The Ōkura mansion is the centre; the hills and the sea are the defence, and the passes are tracks.

Trade and crafts

Rice, salt, fish and cloth by sea through Yuigahama and Mutsuura; Song copper coin in use; armourers and smiths; carvers and painters of the Nara and Kyoto schools working for the Minamoto temples (recalled).

What the year holds

What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

In 1200

  1. Shōji 2/1/13 (about 30 January 1200)First anniversary of Yoritomo's death at the Hokkedō.Depends on: The household at peace Stopped by: Only an order of Yoriie's, or the removal or death of Masako; it is a custom, not a decision.
  2. Shōji 2/1/20 to 23 (about 6 to 9 February 1200)News reaches the city that Kajiwara is dead in Suruga and that Miura Yoshizumi has died; the sixty-six and the Hōjō have won the winter.Depends on: The roads and the news speed Stopped by: Not known: no source says what would prevent it.

Later, on the likely course

  1. Kennin 3/9 (October 1203)Fighting in and round the city: the Hiki quarter is burned; Yoriie is sent to Izu.Depends on: The Hiki and Hōjō quarrel Stopped by: A Hiki victory

Places of note

  • Ōkura mansion (Ōkura gosho): Yoritomo's mansion, seat of the Mandokoro, Monchūjo and Saburai-dokoro (site approximate)
  • Tsurugaoka Hachimangū: The Minamoto war-god shrine at the head of Wakamiya Ōji
  • Yuigahama: The beach where ships are drawn up and the town ends

Where the sources disagree

  • The campaign board puts Kamakura at 35.319 139.55, the gazetteer at 35.309 139.550: both fall in the valley; the campaign board's is nearer the shrine.

Evidence: The place is well attested; the details of the streets are recalled.

"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.

On the map: The near land is drawn as seeds round the town; rights over men are scattered.
