Sister city

We are promoting an exchange business in partnership with one overseas city (Belmont, Western Australia).

City of Belmont, Australia (partnered in October 1984)

Adachi Park
​ ​The City of Belmont, about 3,000 kilometers west of Australia's capital Canberra, located in the Western Australia state capital Perth.
It has Perth International Airport, a population of approximately 43,000 and an area of 40 square kilometres.
The exchange began when Belmont City made a proposal after seeing an English-language graphic magazine published by Adachi Ward to commemorate the 50th anniversary of the ward's establishment.
Adachi Park in Belmont city has become the resting place of citizens.

Sister city exchange business

In 1986, Adachi Ward and Belmont City began to send student delegations to visit local schools and public facilities, and to exchange through homestays. Since then, more than 1,000 ward residents and students, including members of the general public, have visited Belmont City.

Since 2020, students at ward junior high schools and Belmont High School have continued to interact online, even though the impact of COVID-19 has made direct travel difficult.

In January 2024, we welcomed a student delegation from Belmont for the first time in five years, resuming exchanges.

40th anniversary of sister city partnership

Adachi Ward and Belmont City celebrated their 40th anniversary of sister city partnership on October 1, 2024.

In January 2025, a Belmont City delegation of 26 members visited Adachi Ward, where they toured facilities within the ward, observed classes at a junior high school, and participated in a Japanese cultural experience.

At the welcome party celebrating the 40th anniversary, a signing ceremony was held, where the Memorandum of Understanding for the Development of the Sister City Partnership between Adachi Ward and Belmont City was signed and exchanged. Commemorative gifts were also exchanged, and Belmont City donated a piece of glass art to Adachi Ward. The donated glass art was titled "Rebirth" and represents the deep bond between the two cities, as well as their mutual growth, rebirth, and prosperity.

To commemorate the 40th anniversary of the sister city relationship, a cherry tree (Somei-Yoshino) was planted in Belmont Park. Belmont City has also planted a plum tree (Sumo-ume) in Adachi Park, so that the Adachi cherry tree and Belmont plum tree will watch over the friendship between the two cities for many years to come.
