Goryo cigars were produced for the Empress Meiji. In 1908, they were 2 sun and 4 bu (2.86 in) and 7 sun 5 rin (0.895 in) diameter.
Before 1945, no other persons were permitted to enter the production room, while workers were fastidiously checked for health. In 1973, six or seven veteran workers produced it, making all the tobacco and packaging it by hand.
