Awashima's Missing Post Office: Letters Without an Address
On Awashima, an art project keeps letters with nowhere to go. See what makes it moving, when to visit, how to reach the island and the terms for sending a letter.
Who would you write to if the address did not have to exist?
On Awashima, an island in Kagawa Prefecture, the Missing Post Office keeps letters addressed to people, things and moments that ordinary mail cannot reach. This is artist Saya Kubota’s project in a former post office, independent of Japan Post. Mitoyo City’s explanation
It is an unusual destination built around a familiar impulse: having something left to say.
Research note: This article is based on official visitor information, festival records and the project’s publisher, checked on September 26, 2026. We have not visited in person.
A collection held together by impossible addresses
The 2013 Setouchi Triennale report lists Kubota’s Missing Post Office as artwork 128 on Awashima. That festival record places the project within an island art programme, giving some context to the name on the door. Official festival report, printed page 9
A book of the project offers a sense of its range. Shogakukan’s description of Kubota’s collection of 69 letters mentions messages for a grandchild ten years in the future, a deceased family member, a dog and even Voyager 1. Those are examples from the book, not a promise that particular letters will be on display when you visit. Publisher’s description
That mixture is what makes the idea interesting. It leaves room for grief, affection, imagination and things too small or strange to fit neatly into a formal occasion. You might arrive thinking about the person you would write to, then find yourself considering why somebody else chose an entirely different recipient.
For us, the attraction is the change of pace. A letter asks for attention one sentence at a time. This seems a better place to leave a little space in the day than to schedule as a five-minute photo stop.
Plan around Saturday afternoon

The tourism authority’s English island guide lists irregular closures, so check its latest notice before travelling. Do not plan around a festival’s past special opening dates.
The city says reservations are generally unavailable and limits entry to 20 people because of the condition of the building. You can come simply to read; you do not have to contribute a letter. City visitor information
This article does not assume an English-speaking host or an English-language collection. If reading Japanese is difficult for you, consider visiting with someone who can help. Ask before using a phone to photograph or translate a letter, particularly before sharing its contents elsewhere. Other people’s words deserve more care than a background for a travel post.
Get there by ferry, with a return already chosen
The usual approach is the ferry from Suda Port to Awashima, around 15 minutes. The tourism authority’s access guide directs passengers to buy a ticket before boarding. Check the city’s notices for current ticket arrangements: from October 1, 2026, the Suda office closes for a 12:45–14:15 break. That office break is not a notice of ferry suspension.
Use the city’s Awashima Kisen page for the current timetable and operating notices. Choose both your outward and return sailings before committing to the visit. A short boat crossing still needs a timetable, especially when the place you want to see opens for only part of the afternoon.
If you have extra island time, the English guide also lists Awashima Artists’ Village. Check its own opening notice rather than assuming every art venue follows the same calendar.
Before you send a letter
Read the official submission conditions first: letters cannot be returned, and submission includes transferring their copyright to the project, whose creator is Saya Kubota. The city says a sender’s address is unnecessary. Its page provides the postal format and also allows letters to be deposited in person.
Visitors can read the collection, so treat a submission as something you are comfortable making public. Keep an original or a copy if the words matter to you. There is no need to decide on the spot; the project gives you a reason to think about a letter even if you never send one.
