Red beans
Although the origin of Red Beans is not still determined, there is no doubt that the Japanese have cultivated them from ancient times. The oldest remains in Japan which leave a mark of red beans can date back to 4000 B.C..
Thus, as well as soybeans, red beans have played a very important role in Japanese food culture.
The word for red beans in Japanese is 小豆 and we pronounce it as “azuki”.
1. Kanji -Red beans
To learn Kanji (Chinese characters) is always interesting and beneficial to understand what the word means. Through Kanji, we can virtually grasp not only the meaning of the word, but also the background it was born in. Therefore I’m going to use Kanji as often as possible.

Kanji for red bean is 小豆 which literally means “small bean”.
According to the most supported theory, 小 has its origin in the form of three small grains.
To tell the truth, I cannot understand why three small grains indicate “small”. I guess there must have been some other stories involved.
Anyway, as well as 大, it has a simple appearance and you can memorize it relatively easily (I hope so).

Next is 豆.
According to the most supported theory, 豆 indicates a sacred container used to dedicate agricultural products to gods.
We generally pronounce 豆 as “Ma-mé”.
In the Japanese Kanji world, each character has multiple pronunciations.
Therefore, 小has four pronunciations : 1) shou, 2)ko, 3)o, 4)chii. On the other hand, 豆 has three pronunciations : 1) ma-mé, 2)zu, 3) to(u).
No doubt, this system makes the Japanese extraordinarily difficult.
Pronunciation for 小豆
But why is it Azuki?
You may wondering why 小豆 is pronounced as Azuki.
If you have noticed this point, you are very intelligent.
Even if Japanese Kanji have multiple pronunciations, normal rules cannot allow us to pronounce 小豆 as Azuki.
The simple reason for this exception is that the word Azuki had existed in Japanese society long before the Kanji was given.
Maybe the Kanji 小豆 was chosen to describe its small appearance, whereas the word Azuki had been persistent among people. It is probable that these two combined each other before one recognized it.
2. Nutrition value

As the character shows, each bean is smaller than that of soybeans.
Although red bean is small, it is enormously nutritious.
It contains not only protein but also
– vitamin B1 and B2,
– potassium,
– dietary fiber,
– mineral.
In addition, we cannot forget anthocyanin (a kind of polyphenol) which is the origin of the red color.
3. with red beans
1) Sekihan (red rice)

Red is a symbol of the the Sun, life and something vigorous.
Since antiquity, it is believed that red has the mythical power to drive away misfortune.
In the 17th century, we began to cook rice with red beans in celebrations.
This rice is called “Sekihan” (literally “red rice”). Because the anthocyanin in azuki adds a red color to rice.
Even today, we often offer Sekihan to relatives and neighbors in celebrations. We believe that we share the blessings by sharing Sekihan. By sharing blessings, we can multiply them.
Cooking Sekihan in clay pot
As well as ordinary rice, you can cook Sekihan in a clay pot.
The point is that we prepare Red beans in advance to get the red broth from Red beans. This broth turns the color of rice from white to red.
In this recipe, we use both sticky rice and ordinary rice.

2) Anko(sweet red bean paste)

In Japan, red bean reminds us immediately of “Anko“, sweet red paste widely used in Japanese sweets.
To tell the truth, this “Anko” paste is an ideal food to activate the brain which consumes only glucose as energy.
To decompose sugar to glucose, vitamin B1 is inevitable and it is abundantly contained in red beans.
The “Anko” offers these two at the same time and so it can make us vigorous in a few moments.
