Yamashima

Yamashima (Japanese: 山島), is a island nation located in East Asia. It has maritime borders with Japan to the north. It has a population of about 40,764,892, as of 2021.The capital of Yamashima is Fujimaki, which is the largest city in the country with 5 million people. Yamashima is divided into 17 states and 1 federal district.

Researchers suggest that people had already started settling on Shokishima during the Jōmon Period. It used to be run under a shogunate government around the 1300s until the 1600s. However, over the next few centuries, bits and bits of the country were invaded by more powerful countries. Japan invaded the southern part of Yamahima during the Japan-Yamashima War, causing major conflict with the two nations. Japan took control of all of Yamashima during World War II. It regined over Yamashima until Japan surrendered after the atomic bombings on Hiroshima and Nagasaki.

Prehistory and ancient history
The latest records of Yamashima's existence starts in the Jōmon period around 13,000 BC. It is known for the country's Mesolithic and Neothilic ancient culture.The island's mountain caves were used as homes for the settlers, who started to created clay pottery. These clay pottery items are one of the oldest surviving pottery items in the world. Some examples are now on display in the Fujimaki National Museum of History. By the Yayoi period around 500 BC, many people were starting to practice wet-rice farming in the flat areas of Shokishima and Yoturu. The creation of pottery still existed at the time, but instead the use of copper was more widely used. The creation of bronze mirrors known as dōkyōs were also starting to spread. Around 100 BC, Yamashima had started to receive an early name, Wayochi.

Moru Temple, which is dated to have been built during the Nara period The Nara period (710-784) had marked the beginning of an emerging Yamashima. Yamashiman literature had started to form and spread throughout the islands, and in the Book of Wǔdǎo, the name of Yamashima had started to form. Although the Nara period was a growing stage for Yamashima, a smallpox epidemic originating in Japan had started to spread to the country, killing a fourth of Yamashima's population at the time.

Feudal era
Like in Japan's feudal era, the emergence of the samurai had dominated Yamashima. As more and more samurai turned up, the government of Yamashima was officially founded, making Yamashima an official country. The Kamakura shogunate had started to ignore the islands, and thus the Karuzami shogunate was formed. Although Yamashima was officially separated from Japan by then, they assisted in the repelling of the Mongol invasions of Japan. Buddhism had also started being practiced in 1278. However, the shogunate government was overthrown in the 16th century and replaced with the first republic government in Asia.

Modern era
Around 1863, just 9 years after the Convention of Kanagawa, the United States had started establishing relations with Yamashima. This had started economic stabilization and aid between the two countries. This had also brought recognition of the country to the rest of the Western world, which was not very familiar with the country.

In 1937, the Empire of Japan had invaded Yamashima. The empire had started to have complete control over the country. Residents were forced to live under unfamiliar customs and traditions, making life difficult for many.Yamashima had joined the Allies in World War II, going against its longtime friend. The Yamashiman army fought with the Imperial Japanese Army just outside of Kōdai. Meanwhile, soldiers patrolled several places in Fujimaki, and protests had formed near the Port of Fujimaki. Japanese soldiers had arrested many, but some were shot to death, starting the two-day Toshipōto massacre. 45 Yamashimans were killed during the massacre. The Empire finally surrendered after the atomic bombings of Hiroshima and Nagaski by the United States Navy. After the Yamashiman republic gained independence in 1947, there was a baby boom. The nation experienced great growth in population from 7.4 million to 16.9 million. Yamashima and Japan had signed a treaty to improve relations greatly and improve peace between the nations. By 1989, the population had grown to 32.4 million. The nation had also started research on telecommunications and electronics. Earthquake engineering was also a major industry in the 1990’s. On 2005, Hiroshi Electronics was founded and Yamashima became a signatory of the Kyoto Protocol.
