Japan was worried about the outflow of silver, Zhou Lang told them, in fact, it was not China that needed silver, and told the Japanese shogunate that China now uses gold, and no longer uses silver to make money, and taxes are denominated in gold, and the reason why Japanese silver is still flowing into China is because Japan lacks products, and famous people like Wang Fuzhi of the Ming Dynasty have discussed, "Japan has no goods, only gold and silver", and the late Ming Dynasty scholars are very influential in Japan, and the Japanese also know this truth.

The Japanese shogunate asked Japan what to do, and Zhou Lang's method was to engage in industry, and suggested that Japan should adapt measures to local conditions and combine Japan's favorable conditions in order to prosper.

The Japanese did not listen to Zhou Lang's advice, they were too greedy, they were too urgent, they wanted to become China all at once, they wanted to move everything in China back, so they also set up textile factories, let women workers work in the factory, and issued a declaration that instead of selling women, it was better to let them work.

Japan's iron works, shipyards, and machine factories are all heavily invested by the government.

As a result, he fell into trouble in just a few years, and at this time, the shogunate remembered Zhou Lang's warning a long time ago and humbly asked for advice again.

At this time, Zhou Lang continued to tell the shogunate the truth of adapting measures to local conditions. What Japan wants is not a big reason, but a solution.

Zhou Lang told them that he did not know much about the situation in Japan, but at a cursory glance, Japan has high mountains and dense forests, and there may be a future for logging and papermaking, and Japan is right to develop shipping, but shipbuilding lacks iron, and Japan's iron is too expensive, far less cheap than China's, and shipbuilding can only lose money. Machine factories and textile factories will certainly not be able to do China.

The Japanese were very frustrated, they thought that Japan could not do anything in China, so Japan could only run out of goods.

Zhou Lang encouraged them, believing that the Japanese would definitely be able to make better goods than the Chinese. However, it must be combined with the situation of the country, and cannot be blind. He suggested that Japan should start with the existing advantageous industries, and that all the goods that Japan can export to China under the existing conditions will certainly have a great future in the production of machinery.

The Japanese discovered that the only thing that could be exported was the katana. In the Ming Dynasty, there were folding fans, but now they can't do it in China. Katana swords can only be used as a collector's item for a few collectors who like to collect knives, and the market is very small and cannot be produced by machines.

After Zhou Lang mediated the dispute between the Japanese shogunate and the fallen shogunate, Japan had actually opened the country, and it has always been easier for Chinese to enter Japan, although there are some restrictions, such as only living in the Chinatown area, in fact, entering the interior of Japan without authorization, and the Japanese shogunate rarely pursues it. The Fallen Shogun faction can now smuggle openly, which makes the entry of Chinese into Japan even more unrestricted. When Chinese goods entered Japan, they became legally traded.

However, after the opening of Japan, the loss of gold and silver became more serious, and the Besko copper mine, which relied on industrial production, could not balance the trade at all. Supporting with Chinese borrowing is not always the way to go, and the Japanese are desperate to find a way to make money.

After negotiating with the Japanese shogunate, Zhou Lang expressed his willingness to help Japan, and selected a group of experts from Chinese universities to form a delegation to enter Japan, with only one purpose, to find the advantageous industries that Japan may build.

This act was appreciated by Japan, and the Chinese delegation inspected Japan's products, manpower, and all aspects, and brought back a huge amount of data, which almost opened Japan, a closed country, to the world.

But it was found that Japan is more of a disadvantage. There is tea in Japan, but Japanese tea is mainly green tea, and it does not taste good when made into black tea, so it cannot be exported to the West, let alone the Chinese market. Japan's arable land is scarce and food production is small, resulting in the Japanese generally eating very little, malnutrition, and making it impossible to develop export-oriented agriculture, such as cotton and linen. In the past, it was thought that Japan was rich in minerals, but after investigation, it was found that there were only a few gold, silver and copper mines, and coal mines were also available, and other minerals were generally scarce, and it was possible to export only coal and sulfur, as well as traditional gold, silver and copper, to China, and lack the most demanded iron ore.

However, an agronomist put forward a suggestion, saying that although Japan is far north, Japan's climate is mild and close to the south of China's Yangtze River, which is suitable for planting mulberry and raising silkworms, and there are silkworms in Japan, but the quality is not high.

Zhou Lang hesitated about this suggestion, because he was worried that Japan's development of the silk weaving industry would affect China's interests. Because China is the largest silk weaving kingdom, the silk weaving industry in the Jiangnan region is developed. Allowing Japan to join this industry is tantamount to squeezing the interests of the Jiangnan region.

After hesitating for a long time, Zhou Lang made a suggestion to the shogunate, and the shogunate began to hesitate, because there are silkworms in Japan, but the Japanese still like Chinese silk, and the shogunate is very suspicious that it can gain a foothold in this industry.

Zhou Lang suggested that they might as well try to introduce the best silkworm seeds, the latest sericulture technology, and even mulberry saplings from China, and China would provide a full set of technical support. It is important for Japan to tell the Japanese that one acre of mulberry can feed ten acres of land, and that one acre of mulberry field can feed the population of ten acres of land.

The shogunate decided to give it a try, and Zhou Lang really excluded a large number of technical support teams, including helping Japan develop the mining industry, and the quality of Japan's coal mines was still good. Gold, silver and copper mines continue to be mined and sulphur is being exploited on a large scale. Now help them introduce new silkworm seeds and mulberry seedlings to develop mulberry sericulture.

The mulberry sericulture was finally successful, and the Japanese silk weaving technology had not yet caught up, but a few years later began to export raw silk to China. The quality has reached China's level with the support of China's full set of technical support, but it is still inferior to the Jili Lake Silk in the Jiangnan region, and slightly better than the South China Silk in Guangdong. It can be used as a raw material for mid-range silk products.

Zhou Lang also gave preferential taxes to Japanese raw silk, and the mulberry sericulture finally flourished in Japan, and one-tenth of Japan's fertile land became mulberry fields within ten years. Moreover, new mulberry fields are constantly being opened up, and they are growing rapidly every year.

Mulberry trees are different from tea trees, mulberry trees compete for land with grain, the more fertile the land grows mulberry trees, the better the mulberry leaves, the higher the nutrition of mulberry leaves, the silkworms grow better after eating, and the quality of silk is better. Moreover, mulberry trees have requirements for slopes, and slopes above 30 degrees cannot be planted, so almost mulberry fields must be converted from farmland.

This once made the Japanese shogunate very worried, but the shogunate was worried, and the daimyo did not care, and in order to benefit a large number of daimyos, the people in the territory planted mulberry. They then buy grain from China, one in and one out, and make a lot of profits.

Is it Zhou Lang's purpose to encourage Japan to plant mulberry and occupy fertile land, so that they have to be dependent on China?

It can only be said to be partial.

Zhou Lang's efforts to help Japan develop industries that could balance trade and prevent Japan from collapsing under the onslaught of Chinese commodities or going down other paths could not have been Zhou Lang's love for Japan.

Zhou Lang has only one purpose, to keep Japan as it is. Zhou Lang has no interest in Japan, this land is not worth his attention to because there are few people and there is a lack of mineral deposits, but Zhou Lang is full of defense against Japan.

Guarding against Japan is the reason!
