Truth of Katana

I looked at the video "Katana VS Broadword."

It is the video of the contents "katana had bent when Broadsword was cut with Katana, but broadsword did not bend."
However, primarily, Katana is made of a soft metal and bends easily.

The expert of Katana is competent so that it may not bend.
However, shortly after a user is poor, it will bend.

Since it seemed that many people seldom knew about Katana, I investigated.

The characteristic of Katana

Katana is polished in the lengthwise direction.

katana has the shape of a saw with a detailed edge. Therefore, the maximum power is demonstrated by pulling, or it pushes.

The shape of katana is making the form of the natural arc.

This form is the form which can be smoothly cut while putting the suitable pressure for an edge.

The side of the edge of Katana is roasted by fire.

By this, it becomes very strong against the shock at the time of an edge hitting perpendicularly to an object.

The fault of Katana

Katana of sharpness is wonderful.
However, if the target vital part is not in sight, it will seldom be helpful.
Sharpness of Broadword is bad.
However, anyone can give a fixed damage to a target.

Japanese people make a sword for an expert to use.
The West makes the sword which many people can use.

This has a thing related also to fighter plane.

"Katana" for a Japanese

katana is poor at Western armor.
Probably, it will be difficult for a Japanese army to win, when Japanese samurais' army and an Occidental army fight.

It seems that first of all, Japanese people used not katana but the spear on the battlefield. Katana was used for the duel.

And the sword was also samurais' strong emotional attachment. It was going to reach to an extreme of the technique in which many samurais treat a sword just because it is a sword which cannot pull out sufficient power, if it is not an expert.

Since the body is small and powerless, Asians are poor at brandishing a sword by muscular power.
Therefore, the martial art of medieval Japan and the researcher of kendo were well versed in the field of sports science.
The work to which the bodily center of gravity is moved, and the work which utilizes potential energy and produces big power were invented.

The result is martial arts, such as "karate", "kendo", "judo", and "aikido."
Probably, a Chinese martial art also has the feature similar to a martial art of Japan.



At the end, pretty video is introduced.
This is the woman who is studying "Iaido."



Incidentally, in present age Japan, walking around with Katana without permission is breach of law.
For many Japanese, Katana is not familiar.
Like the woman in video, it can own as the case where Iaido etc. are studied, and an expensive work of art.

Are Japanese people really industrious?

Once, by World War II, Japan died once and was born again.

"was born again."
I would like to express such.

In Japan of prewar days, and postwar Japan, it is changing dramatically.

Japan achieved the big economic growth represented by the "bubble" after the war.

Japanese asset price bubble - wikipedia

What kind of situation does Japan of the period of the economic growth think it is?

- The consciousness as a capitalist state rooted strongly.

- Money-making was completed as it worked, when working.

- Money was not exhausted even if people bought many things needed.

- And all people had an illusion that such a time continued eternally.

However, such a time was ended around 1990.
Henceforth, economy of Japan has fallen rapidly.

And I was born in 1982.
Japan was quickly depressed and has looked at signs that the identity is lost.

And Japan is trying to change now when 20 years or more passed.
I am imagining and enjoying the end at which changing Japan arrives as a one Japanese.

A Japanese labor view

Japanese people are considered to be industrious.
That's right.
National working hours are long to top class also in the world.

Why are Japanese working hours long?
Probably, one has the loyalty to a company.
Japan came considering being faithful to the Lord as a virtue historically.
However, it is not a major factor.

The reason Japanese working hours are long is that it experienced rapid economic growth.
Economic growth changed the sense of values over labor of Japanese people.
The more it works, the more it profits.
Therefore, if time to work is lengthened, it will profit more mostly.

And people of the oldest age experienced the "bubble" among Japanese workers.
A change of generation will take place in ten years, and Japan will change gently.

Probably, a subsequent Japanese is also industrious.
However, it should come to work more efficiently than former.




To all the people that love Japan.
with love.

Japanese faith and animism

"Japanese people do not have an object of faith."
Seemingly, from you outside Japan, it thinks such. 。

A present-day Japanese does going once for a week to neither a church nor a temple.

There are only two opportunities for Japanese people to visit Jinja (shinto shrine) in every year.
But, Japanese people have an object of faith.


Our faith is special.
It is because our faith has rooted into every day.

Shintoism

Shintoism is mentioned to a religion unique to Japan.

It is the religion which makes Tenno (emperor) the highest priest person, and is the religion which shows the respect to nature, and awe.

Shintoism thinks that Kami (God or soul) is dwelling in all the things of this world, a phenomenon, and all.

In Japan, what has after [ Shintoism ] acceptance of Buddhism, Confucianism, Christianity, etc., etc. remained in the Japanese inner life broadly.

When considering faith of Japanese people, a concrete building and substance should pay their attention to soul rather than are important.

"Itadakimasu" and animism

In Japan, before having a meal, the custom recited "Itadakimasu" is.
The animism of Shintoism can say this custom as the custom which remained deeply.

Meat, a fish, vegetables ...
All the foods are conceiving the soul and are Kami.
Their lives are killed and it is used for life maintenance of man.
Japanese people put the gratitude to them and recite Itadakimasu.

Animism and whale gastronomic culture

I may read the blame about what Japanese people eat a whale for through overseas media.

In order for them to say, it is what "It should not kill and they should not eat since a whale and a dolphin have high intelligence although a pig, a cow, and vegetables may be killed."

However, according to animism faith of Japanese people, they are a pig, a cow, vegetables, a whale, a dolphin, and a soul valuable like all.

Those who blame eating a whale have a haughty belief to the soul which you are killing and eating.

It is discrimination.




By the way, a whale may be delicious ...
In fact, Japanese people rarely eat a whale.

Whale meat is due to be introduced by a Foods category someday.
