Jufukuji (to be founded in 1200)

Jufukuji does not exist on 1 January 1200.

Masako founds it in the course of 1200 on the old residence of Yoritomo's father Yoshitomo in the valley of Kamegayatsu (Ōgigayatsu), to pray for Yoritomo, and invites the monk Eisai, who has brought tea and Rinzai teaching from China, to be its first abbot (English Wikipedia: 1200; month and day not pinned). It is a Zen and Tendai-Shingon-Zen house at first, as Eisai held to the old schools. Eisai will found Kenninji in Kyoto in 1202 and write the treatise on tea.

The great Zen temples of Kamakura, Kenchōji (1253) and the Great Buddha (1252), are much later.

Masako as patron; the Mandokoro for the land

What it holds

  • Endowments from Masako (to be given)

How it was acquired

Not yet founded; on the likely course Masako founds it in 1200.

Allies and rivals

Masako's foundation; Eisai's rivals are the Tendai at Mount Hiei, who attacked his Zen in Kyoto.

How things stand that morning

Threats

  • Tendai opposition to Eisai

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.

Places of note

  • Jufukuji site: The old house of Yoshitomo at Kamegayatsu (to be built in 1200)

Where the sources disagree

  • The campaign board's calendar says Masako calls Eisai east and founds Jufukuji in 1200: accepted. 'Kamegayatsu' is the old valley name; the English page gives the modern address Ōgigayatsu.

Evidence: One good English page for the year; the month is not given.

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

On the map: Point only; not built on 1 January.
