Captain F. Brinkley, Japan: Its History, Arts, and Literature… (1902)
“ The currency system, established by Japanese financiers at the beginning of the Meiji era was based on the gold standard, the unit being the gold yen a coin worth four shillings, in round numbers. But, in the first place, Japan's stock of gold was soon driven out of the country by her depreciated fiat currency, and, in the second, as all other Oriental nations were silver-using, and as the silver Mexican dollar was the unit of accounts in Far-Eastern trade, Japan ultimately drifted into silver monometallism, the silver yen becoming her unit of currency. ”
