Sengoku Period Art of Survival

1. Surviving without a pot or kettle
When at war, we must steam rice even without a pot or kettle.
As a method for making steam rice in times of emergency, let’s effectively use things close at hand. The way is no doubt well-informed.
Put rice into a hand towel and wet it well with water. Dig a hole in the ground, and bury the rice filled towel. Cook it by lighting fire on top of that. If you don’t have a towel, a straw or goza mat can be used instead to cook it in the same way. You should remember how to light a fire as common knowledge.

2. The Dangerous Trap of Raw Rice
In times of emergency, how should we eat raw rice?
In the feild, long rains were a powerful enemy. There were also times when there was no fuel, or they couldn’t use a fire. In the Warring States Period, there were times when they had to eat raw rice because they couldn’t use a fire. But however hungry you are, I can’t recommend raw rice. Immediately, you will get a stomachache. When you must eat raw rice so matter what, there is nothing to do but eat it after soaking it in water for about four hours. It’s said that at the Battle of Sekigahara, the Sengoku warriors who couldn’t wait four hours for their hunger being so fierce, were altogether sick in thier bowels. A simple but lengthy method to try.

3. Seasonings During War Time
During a battle, something even more frightening than running out of rice was a shortage of salt. Of course rice, but also foods like miso with a high salt content had to be carried in a portable to war. This, too, was one way to make war. Take, for example, miso. Potato stalks could be soaked and boiled together with miso and rolled into a cord shape. Also, vegetables like dried daikon could be boiled and dried with the same method. Or a board could be coated in miso. Such sun dried items could be easily carried to the battlefeild.
After being coated in miso, dried vegetables could be chewed on straight like that or they could be put in hot water to make miso soup. It’s just like modern instant miso soup.
Furthermore, when their opponent was far off, or it seemed it would be a long battle, generals of the Warring States Period slightly altered this portable method.
