On a quiet island in Japan sits a wooden building that processes mail addressed to the dead, future descendants, and lost first loves. This facility has no official ties to the national postal service, yet it collects messages from across the globe that have nowhere else to go.
Visitors wander through the structure reading postcards from strangers. Anyone who feels a specific message is meant for them is permitted to take it home.
Awashima Island Art Installation
The Missing Post Office, or Hyoryu Yubinkyoku, began as an artwork by Saya Kubota for the Setouchi Triennale festival in 2013. Kubota conceived the idea after visiting Awashima Island in Kagawa Prefecture. Seeing her reflection in the window of a retired post office, she felt she had washed up on the shore.
The structure was built in 1964 and operated until 1991. Located a ten-minute walk from the port, the building was renovated for the festival. Kubota acts as the worker, while Katsuhisa Nakata, the actual former postmaster, serves as the postmaster for the project.
Suspended Metal Post Office Boxes
Inside, the mail is stored in an unusual system. Kosuke Nagata and Junpei Matsushima constructed one hundred metal boxes suspended from the ceiling by piano wire. Because the letters lack standard addresses, the boxes are not fixed in place. When visitors turn them, they produce a sound mimicking ocean waves.
The facility asks people to send undeliverable thoughts via postcard using a general delivery address. Senders do not need to include a name. Staff members do not track which message goes into which box. After a visitor reads a postcard, it continues to drift throughout the room.
Global Reach and Letter Counts
The project opened in October 2013 with a 300-yen entrance fee. During the month-long festival, the site collected approximately four hundred pieces of mail. After the festival concluded, the site kept receiving about two hundred pieces per month, prompting Kubota to keep the doors open.
By May 2014, the collection surpassed 1,500 messages, attracting the attention of NHK television. The inventory grew to over 3,800 messages by February 2015. As of November 2022, the facility operates on the second and fourth Saturdays of the month.
Off-Island Exhibitions
The project eventually expanded beyond the island. In August 2014, a temporary branch was installed at Takamatsu Airport, and an international London branch opened in January 2016. The post office also hosted a live music event featuring a band of active monks.
The concept reached mainstream audiences through print and television, including a published book by Shogakukan in 2015 and an appearance in the 2022 Fuji TV drama series Don’t Call it Mystery.
