On the small island of Awashima in Japan, a shuttered post office has become a resting place for undelivered letters. Inviting words to the dead, to future selves, and to lives that turned another way, letters with no onward journey fall into the hands of retired postmaster, Nakata-san, 91, who tends the silence and solitude like a garden. Reopened as an art center by Japanese artist Saya Kubota, the Missing Post Office welcomes visitors to read the letters from a room kept open just a few hours each week, meditating on the quiet philosophy inscribed in notes of grief, love, and gratitude.
