Why do you think Japan closed their country for 250 years?


Japan’s decision to close its country for 250 years is a fascinating topic that has intrigued historians and scholars for centuries. The isolationist policy, known as Sakoku, was implemented in 1633 and lasted until 1853 when the country was forced to open its borders by the United States. This article will explore the reasons why Japan closed its country for such an extended period and the impact it had on the country’s political, economic, and social development.

The Threat of Christianity

One of the primary reasons why Japan closed its country was due to the threat of Christianity. In the early 16th century, Christian missionaries began arriving in Japan, and their influence spread rapidly. However, as Christianity became more widespread, tensions between the Japanese government and Christian converts grew. The government saw Christianity as a threat to their power and banned it in 1612. The ban was followed by harsh persecution of Christians, including torture and execution.

The Need for Control

Another reason why Japan closed its country was to maintain control over their society. The Tokugawa Shogunate, who ruled Japan at the time, believed that closing their borders would help them maintain their power and control over the country. They feared that outside influences would disrupt their carefully crafted social order and lead to chaos.

The Fear of Invasion

Japan’s decision to close its country was also influenced by a fear of invasion. At the time, Japan was a relatively weak nation compared to its neighbors, such as China and Korea. The government feared that opening their borders would make them vulnerable to invasion or conquest.

The Desire for Autonomy

Another reason why Japan closed its country was a desire for autonomy. The Tokugawa Shogunate wanted to create a self-sufficient society that did not rely on outside trade or influence. They believed that closing their borders would help them achieve this goal and allow them to maintain their independence.

The Impact on Japan’s Economy

Japan’s isolationist policy had a significant impact on its economy. Without access to international trade, Japan’s economy stagnated, and the country fell behind other nations in terms of technological advancement. However, Japan did develop a unique and self-sufficient economy that relied on domestic production and consumption.

The Impact on Japan’s Social Development

Japan’s isolationist policy also had a significant impact on its social development. The policy resulted in a highly homogenous society that was resistant to outside influence. This homogeneity led to the development of a strong sense of national identity and a unique culture that is still celebrated today.

The Impact on Japan’s Political Development

Japan’s isolationist policy also had an impact on its political development. Without outside influence, the Tokugawa Shogunate was able to maintain control over the country for an extended period. However, this isolation also made Japan vulnerable to internal dissent and rebellions.

The End of Sakoku

Japan’s isolationist policy came to an end in 1853 when the United States forced the country to open its borders through a series of treaties. The treaties were followed by a wave of modernization and industrialization that brought significant changes to Japanese society.

The Legacy of Sakoku

Despite ending over 150 years ago, the legacy of Sakoku can still be seen in modern Japanese society. The policy played a significant role in shaping Japan’s unique culture and national identity. It also left a lasting impact on Japan’s economy and political system.


In conclusion, the reasons why Japan closed its country for 250 years are complex and multifaceted. The policy was driven by a desire for control, autonomy, and a fear of outside influence. While it had a significant impact on Japan’s development, it also led to the creation of a unique and self-sufficient society that is celebrated to this day. Understanding the legacy of Sakoku is crucial in understanding modern Japanese society and culture.

Why did Japan become a closed country?

The sakoku policy, which restricted contact with foreign countries, was believed to have been implemented by the shogunate to prevent the influence of Spain and Portugal, seen as a danger to the shogunate’s power and the peace of the Japanese islands.

Why did Japan end 200 years of isolation?

In 1853, Japan’s period of isolation was broken when Commodore Matthew Perry, leading a group of two steam ships and two sailing vessels from the US Navy, arrived at Tokyo harbor.

How long was Japan closed to the world?

Japan remained isolated from the rest of the world for 220 years due to the implementation of the “closed country” policies.

What did the 250 years of national seclusion do for Japan?

Japan was isolated from Western countries for 200 years after the Act of Seclusion in 1636, except for a small Dutch outpost located in Nagasaki Harbor.

What is meant by Japan’s closed country policy?

From the beginning of the 17th century, Japan’s samurai leaders had a policy called sakoku, meaning “closed country,” which prohibited foreigners from entering Japan and prevented Japanese citizens from leaving and then returning.

Is Japan a closed or open economy?

Japan’s economy is not open to foreign companies and products and does not react to market forces like other countries do. Those who support a results-based approach to Japanese trade generally believe that a managed trade system is not the best solution.

Furthermore, the legacy of Sakoku has also had an impact on Japan’s foreign relations. Even after opening its borders, Japan remained wary of outside influence and maintained a policy of limited engagement with the international community. This policy continued until the late 19th century, when Japan began to pursue a more aggressive foreign policy and embarked on a path of imperialism.

Today, Japan is known for its unique blend of traditional culture and modern innovation. The isolationist policy of Sakoku played a significant role in shaping this identity, as it allowed Japan to develop its own distinct culture and social norms. This legacy can still be seen in modern Japanese society, from its strong sense of national identity to its emphasis on tradition and respect for authority.

Despite the many challenges that came with Sakoku, there were also benefits to the policy. By closing its borders, Japan was able to maintain a degree of autonomy that allowed it to develop its own unique political and economic systems. These systems were highly effective at meeting the needs of the Japanese people, and they continued to evolve long after Sakoku came to an end.

In conclusion, while the legacy of Sakoku was complex and multifaceted, it played a significant role in shaping modern Japanese society. From its impact on the economy to its influence on politics and culture, Sakoku left a lasting impression on Japan that continues to be felt today. As such, understanding this policy is crucial for anyone seeking to understand Japan’s rich history and unique identity.
