1. Japan has formulated a development strategy suitable for its national conditions. As Japan is an island country in East Asia, surrounded by the sea on all sides, after World War II, Japan formulated the development strategy of "building a country by processing trade" according to its national conditions, seized the favorable opportunity of peace and stability, gave full play to the advantages of marine economy, and established the development strategy of "building a country by processing trade" by taking advantage of the low price of raw materials after the war, which greatly promoted the recovery and development of its economy. At the same time, the industrial support policy, industrial adjustment policy, industrial technology policy, industrial protection policy and industrial organization policy are combined with relevant economic plans to ensure the revitalization of enterprises.

2. The United States began to help Japan recover its economy. In the early postwar period, Japan's foreign trade was mainly Japan-US trade, and Japan was an important market for American goods. In order to enable Japan to import American goods, the United States has established various revolving funds.

3. Pay attention to the education of national science and technology. After World War II, under the supervision of American occupation forces, Japan carried out the second educational reform in history. This educational reform has lasted for about 6 years, which is another comprehensive and thorough educational reform after the first educational reform during the Meiji Restoration.

4. Good national quality, Japanese people's love and selfless dedication to the country made them devote a lot of energy to national construction, which became one of the important reasons to promote Japan's rapid economic rise after World War II.

5. The government actively encourages private and state-owned enterprises to purchase foreign patented technology and monopolize various industries as much as possible. Japan has collected patent fees from many other manufacturers, so many industries are monopolized by Japan, and money keeps rolling into their pockets.

Extended information:

On August 15th, 1945, Japanese Emperor Hirohito had to announce Japan's unconditional surrender in the form of broadcasting "Imperial edict", which marked Japan's complete defeat in the Second World War. This failure has greatly reduced Japan's comprehensive national strength, caused heavy losses to young and middle-aged Japanese labor force and scientific and technical personnel, destroyed a large number of factories and schools, and plunged the economy into a trough.

in addition, Japan's small territory (less than 4, square kilometers) and lack of various resources have plunged Japan into a serious crisis. Many Japanese nationals have no hope for the rejuvenation of the country.
