The twinning agreement between the two cities was signed on July 1, 1965. Yokohama and Odessa have many things in common: both cities are international ports and were rebuilt after being destroyed during WWII. For the last five decades, the two Sister Cities have been cooperating in many fields, such as culture, sports and healthcare.

Yokohama is located in the centre of Japan, along the coastline of the Pacific Ocean, and is one of the 15 Japanese Government-designated cities. The total population of Yokohama is 3.7 million persons, making the city the second largest one after Tokyo. Many foreign enterprises have established their branches in Yokohama because of its international trading port.

Yokohama, was the first harbour city opening to the world as the entrance to Japan, kicking off the modernisation of Japan in the 19th century. Since then, Yokohama has been vigorously acquiring new cultures from foreign countries and introducing to Japan first-time-ever things from food to a wide range of products, which entitles Yokohama as the birthplace of Japan’s modern culture.

Yokohama is a lively international port town and a city of art and culture, continuously generating new urban values and fascination. Yokohama boasts not only international museums and unique objects placed in the parks, naturally incorporated with the harbour cityscape, but also offers the experience of the Japanese traditional popular arts. The city preserves cultural facilities such as museums, classical music hall or Noh (Japanese traditional masked dance-drama) theatres, and utilise local old warehouses and historical buildings, to promote the economic revitalisation of the city. Its port views are a unique and attractive townscape for residents and visitors.
