In the early 8th century, edicts were issued in 707, 708 and 717 stipulating that an offense of a mountain valley exile would be condoned if the offender handed oneself in within 100 days, but they were part of amnesty and a copy of edicts in Tang Dynasty China.
8世紀初めには、慶雲4年（707年）、和銅元年（708年）、養老元年（717年）と、百日以内に出頭すれば亡命山沢の罪を赦すという詔が出たが、それは大赦の一部で唐の詔を引き写したものである。
