Located inside the Hiroshima Peace Memorial Museum, this unique mailbox allows visitors to send postcards of peace directly from the heart of the park. It is a deeply moving way to reflect on your visit and share your thoughts on peace with loved ones back home. Postcards mailed here receive a special, commemorative postmark, making it a meaningful and highly personal souvenir.
Purchase a postcard at the museum shop beforehand, and write your message there to save time when you reach the mailbox.
