| 背面描述 | Plain reverse with a central square perforation, surrounded by a raised square boss. The field between the inner boss and the outer rim is unadorned, exhibiting the characteristic flat, uninscribed surface typical of early Japanese cast cash coinage of the Nara period. The surface shows extensive patination consistent with age, with a raised inner and outer rim framing the otherwise blank field. |

The Mannentsūhō was issued under Emperor Junnin in 760 as part of Japan's early imperial coinage system, its value pegged at ten times the preceding Wadōkaichin — an ambitious denomination jump that the market largely refused to accept. Hoarding began almost immediately, as holders recognized the overvaluation, and the coins disappeared from circulation within years of issue.
Junnin himself was deposed in 764 by Empress Shōtoku, exiled to Awaji Province, and dead within a year under disputed circumstances. The coinage bearing his reign effectively ended with him.
