Auctions in Japan

[sun_moon]

i know this is a long shot but here goes.
im asking if anyone knows some car auctions in japan ??
as im looking to buy two cars. im located in tokyo, so anywhere in kanto is fine.
please do NOT list places in kansai, as i cbf going there.

im looking for a red aw11 SC MR2 to import as a pre 1989 car, and also im looking to import a red honda NSX under SEVS scheme as a private import (i will own it in japan for a year and then ship to aus), where as the aw11 i will buy and instantly send back to australia.

any help is greatly appreciated. thanks guys.
