Osaka History

Osaka has a rich history dating back over 1400 years. As far back as the 5th century, Osaka was an economic and political center of Japan, mainly because of its access to sea and river routes for traders and travelers. Visitors from Korea, China and throughout Asia gained access to what is now the city of Osaka through the Naniwazu Port, which is currently the port of Osaka. Travelers to the area brought new technology in ceramics, construction and engineering. Travelers also brought Buddhism, which quickly spread throughout the area.

A series of civil wars led to the devastation of the area during the 14th century and conflicts continued over the years, leading to the destruction of the Ishiyama Honganji Temple and the later destruction of the Osaka Castle city. The city was later rebuilt from the ashes that remained from civil war and during the Edo Period from 1601 to 1867, became known as “Japan’s kitchen” because the port shipped essentials throughout the country and internationally. As Osaka became an economic hub, it also became known for its arts and culture.

In 1868, the city transformed from one known for trade and finance to a commercialized area, leading to the 19th century nickname “smoky city” because of its factory smokestacks. Osaka was officially incorporated in 1889 and has continued to thrive in terms of its culture and economy. Years following led to the first streetcar in Osaka, the hosting of the 5th National Industrial Exposition, and by 1925, Osaka was the largest city in Japan by both population and area.

Today, Osaka has a flourishing economy. The “Food Capital of Japan” is renowned for its varied, abundant and delicious cuisines, and the city has over 100 Michelin star-rated restaurants. The area is a popular destination for tourists, who partake in the delicious restaurants, shopping and visiting historic landmarks such as the Osaka Castle.

Osaka Population Growth

The population of Osaka has declined in recent years, and the declines have been attributed to residents moving from the city into the suburbs. In 1930, Osaka was the largest city in Japan, outnumbering Tokyo by over 400,000. The city saw a peak population of over 3.2 million in 1940. Osaka, like other cities in Japan, is experiencing a decline in population. The 2015 census that tracks the period from 2010 to 2015 shows that Osaka’s decline was the city’s first in almost seven decades. The declines in both the city and the country as a whole have been attributed to historically low fertility rates and deaths that have outnumbered births by about 200,000 in recent years. Future forecasts show that the city will experience a decline in population over the next few years, hitting 2.05 million by the end of 2020, before declining further to less than 2 million in 2030.
