Ninja’s secret food stakeout! Hyorogan making experience -online event-

  • 2021.10.22

For ninjas, whose missions expected them to endure long periods of time, the portable food “Hyorogan” was more than a throwing shuriken star. Ninja could sustain a 7-day-long mission with just one Hyorogan bite. Based on the recipe from the work “Collection of old stories about Koshu style Ninjas” written in the latter half of the Edo period, the ninjas of the Studio Park will teach you how to make the secret Hyorogan online. This autumn, when ninjas become more popular, spend some time at home as if you were one of them!

What is Hyorogan?

Hyorogan is a portable preserved food that is said to have been eaten by ninjas from the Sengoku Period to the Edo Period in Japan. It was essential not only to fill the stomach, but also to better endure the harshness of their missions. It is said that during the Sengoku Period, not only ninjas would eat it, but also their warlords.
