Otokoyama began in 1887 as Yamazaki Shuzo. In 1968 it took over the Otokoyama brand, made by brewers in Itami in the Edo period. In 1977 its junmai daiginjō became the first Japanese sake to win a Mondo Selection gold medal.[19]
The museum in Nagayama is free and gets about 200,000 visitors a year. Its spring water, the “Water of Long Life”, is free to take, up to 20 L per person. Tastings and the shop have moved next door, to a new shop called OTOKOYAMA SAKE PARK.[27]
On the second Sunday of February the brewery opens its doors in the middle of the brewing season, with new sake to taste. The open day has run since 1979 and now draws more than 10,000 people.[19][27]
