the new technology

The amount of silver produced in Japan was originally not large due to technical problems.

"1：5～６."

Until the early 16th century、the price ratio of gold and silver in Japan seemed to be around this level.

But 16th century.

Japan was in the Warring States period、and within Japan there were many struggles for existence、in other words wars、between warring states lords.

Many of them actively developed mines to earn more war expenses.

And in the 1530s、Korean smelting engineers brought new technology to Japan.

It called Haifuki-hō.(灰吹法)

As a result、the amount of silver produced in Japan increased dramatically.

"１:10～13."

At the beginning of the 17th century、the price of silver fell to this point.

In short、during the 16th century、silver's price fell in half.

(In practice it was 50 years of late the 16th century.)

Japan became one of the world's leading producers of silver.

At that time、output of silver in Japan seems to have been about 25～33％ in the world.

"The price of silver in Japan was cheaper than in neighboring countries."

This may be natural.

・・・・・・・・・　

The early 17th century、of course、it was already the time of the Tokugawa Shogunate.

Silvers export volume was reached 200,000 kg at the maximum value.(per year)

"Gold 1 = Silver 9,6824073563"

By the way、this was the exchange rate of gold and silver by the Tokugawa Shogunate.

This is less than 10.

Increased production of silver was still going on.

"Gold 1 = Silver 13"

In fact、this was the actual exchange rate at the time.

There is such a possibility.

Probably Tokugawa had set high price of silver than the market.

※Did they do the transaction settlement with gold？

※Speaking of which、although the topic is slightly different、but maybe I feel that Ｉ read a story long ago that settlement money was different in east(Edo) and west(Osaka).

However、this exchange rate was、so to speak、a principle、and the market rate was constantly fluctuating.

And perhaps the price of silver was lower than the official rate.

Therefore overseas trade might have been traded by the market rate.

But Japan at that time had a policy of national isolation.

The overseas trading area was limited to a small part of Nagasaki city.

And the Tokugawa Shogunate had a monopoly on it.

However、even at the official exchange rate、the price of silver may have been lower than in other countries.

(Just maybe、there was a rate for overseas trade.

At this point、I don't know much about foreign trade at the time.）

※Basically、I think that trading countries at that time were only China and the Netherlands.

There may have been like agents(unofficial) for other countries in there.※

・・・・・・・・・　

For example.

200,000 kg is 200,000,000 g.

Gold 15,492015g = Silver 150g

Gold 1g was ¥ 4,245.(as of Jun 17, 2013 19:15)

4245×15,492015＝65763,603675

200000000 ÷ 150 = 1333333,33333

1333333,33333 × 65763,603675 = 87684804899,78

Trading of ￥87,684,804,900 at the official rate of Tokugawa.(rounding)

recast

However、silver production was already declining by the mid-17th century.

In 1668、the Tokugawa Shogunate finally banned the export of silver.

"1ryō is silver coin 60 monme."

And Tokugawa changed the exchange rate in 1700.

60×3,75×0,8＝180g

Gold 15,492015g = Silver 180g

180 ÷ 15,492015 ＝ 11,6188888275

Gold 1 : Silver 11,6188888275

Price ratio became this.

Perhaps the Tokugawa Shogunate took this opportunity to match the actual market price.

(Of course、even after this、the market was a rate fluctuation system.)

※150 and 180、it is a number I saw somewhere (lol).

By the way、now I do not know the process、but the price of silver is falling.※

※This is probably.

3,75 is the weight of 1 monme.

0,8 is the content ratio of silver.

20220926.※

・・・・・・・・・

By the way、little before this、in 1695 Tokugawa recast the gold and silver coins.(改鋳/Kai-chū )

Second half of the 17th century、gold production was also fell as with silver.

By contrast、Japan economy was continuing to expand.

"There is a high possibility that the amount of coins currently in circulation will not be able to support the future market economy.

Increase the amount of coins circulating in the market by lowering the coin content."

This recast was done in this intention.　

Gold 15,492015g = Silver 180g

Therefore、both comparisons based on this may be wrong.

However、gold and silver contents seem to have fallen at the same rate (the same ratio when comparing both).

Gold 1 : Silver 11,6188888275

Price ratio at that time would not be wrong in this.

・・・・・・・・・

According to it.

First gold coin of this shape called Keichō-Koban.(慶長小判）

It seems that the total production volume can not be known due to the loss of documents.

But amount of its recast(引替/Hikikae)、there was this.

However、probably this recast was "as Keichō-Koban(restore？)".　

There is no change in the gold content in the Koban.

Incidentally、Japan has a period division called Gengō.(元号).

※Originally、it began to be used in Chinese Han Dynasty.

Simply put、until the first imperial empire of China "the Qin dynasty"、for example、it was counted in each country as "the 20th year of king Georg (for example)".

Oh! same as Japan after the Meiji era(lol).

Until that time、Gengō was usually changed several times during the one's reign.※

It seems that it is impossible to replace it with the A.D as it is.

"1606-1694(not accurate)

Amount of recast of keichō-koban is 10,527,043 ryō."

※I do not know now how many duplicates there are.

Gold 15,492015g　

Gold 1g was ¥ 4,245.(as of Jun 17, 2013 19:15)　

When calculated in this number.

10527043 × 15,492015 × 4245 ＝ 692296283718　

Amount of gold coin recast of 1606-1694

Gold 163085108g
