Genroku (元禄) was a Japanese era name (年号, nengō, "year name") after Jōkyō and before Hōei.
There were unanticipated consequences when the shogunate debased the quality of coins as a strategy for financing the appearance of continuing Genroku affluence.
Then, in an effort to solve the ensuing crisis, the bakufu introduced what were called the Kyōhō Reforms.
The previous era ended and the new one commenced in Jōkyō 5, on the 30th day of the 9th month.
A sense of optimism is suggested in the era name choice of Genroku (meaning "original happiness").
