burial

There was anthology named "Manyoshu" of japanese poems that was made around the 8th century.

”Soul of the dead will go to the mountain.”

Sang also in that poem.
However there was no poem about the body that is left.　
　
Soul was most important for Ancient Japanese people.　
Body after the soul had been disconnected.
That was regarded as not important.　
　
・・・・・・・・・　

Burial customs began in 11,2 century in the aristocracy.　
Then it was spread to the masses.　
　
"You can go to joudo if you are burial to Koyasan."　
　
"Koyasan" is head temple of the Shingon sect of Kukai.
At the time, there were many informal monks who preach so.
　
This burial customs had linked with thought of Joudo in mountains.
And burial was began in lingshan of throughout japan

”That way body and soul meet again in mountain.”

They believed so.

・・・・・・・・・

The mid 11th century，there was a man named Abe-no-sadato in northeast region of japan.
Era he was alive, there was a great revolt there.　
　
At that time，originally people who lived of this land called "Emishi".
（Not the name of a race.）
They had been exploited as people who were conquered.　
　
He battled as a member of the rebel，and he was executed after revolt defeat.　

・・・・・・・・・

There is active volcano named Issaikyou mountain on north of Joudo-daira.
Issaikyou meaning is Complete Buddhist scriptures.

"Abe-no-sadato did buried Issaikyou to this mountain."

There was its legend，and it had became the origin of the name of Issaikyou mountain.
However just maybe buried ones in the mountains that was his body, not Buddhist scriptures.
Or dead soldiers bodies who fought with him.

Of course that was burial that pray for happiness after death.
