It took place in the Shimabara Domain under the Tokugawa shogunate. This uprising was one of the largest civil fights during a peaceful time in Japan. Most people believe the rebellion was caused by anger toward unfair rules. Many people felt the local leaders were treating them poorly. This led to a massive struggle between the people and the government.

The trouble started because of high taxes and hard lives. Two lords, Matsukura Katsuie and Terasawa Katataka, ruled these areas. Matsukura Katsuie raised taxes to pay for building a new castle. He also strictly banned the Christian religion. Many people in the area were Catholic, so they felt targeted. Famine also made life very difficult for farmers and fishermen. These people eventually joined with masterless samurai called rōnin to fight back.

A young leader named Amakusa Shirō emerged to lead the rebels. The group began their uprising on December 17, 1637. They moved to a place called Hara Castle to make a stronghold. They used wood from their boats to build strong walls. The rebels also used weapons they took from local storehouses. They were joined by many peasants and former samurai. This group was quite large, with some estimates reaching 37,000 people.

The Tokugawa shogunate responded with a massive military force. They sent an army of over 125,000 soldiers to stop the uprising. The shogunate even asked the Dutch for help with cannons and gunpowder.

A famous swordsman named Miyamoto Musashi was even there as an advisor. The fighting lasted through a cold winter at Hara Castle. The rebels won some battles, but they soon ran out of food. By April 15, 1638, the government forces finally won the fight.

The rebellion changed how Japan interacted with the rest of the world. After the fight, the government executed an estimated 37,000 rebels. They also forced Portuguese traders to leave the country. This made Japan's policy of national seclusion even stricter. The ban on Christianity was also enforced much more heavily. This meant the religion could only be practiced in secret. The Shimabara Domain was eventually given to a new leader named Kōriki Tadafusa.
