Located on the seabed of Susami Bay in Wakayama Prefecture, the underwater postbox has become a unique attraction for tourists and diving enthusiasts. The postbox was installed in 1999 as part of an effort to promote tourism and attract more visitors to the area. Despite its unusual location, it is essentially a regular postbox securely fixed to the seabed. According to available information, more than 1,500 letters are sent from the underwater postbox every year, turning an ordinary act of mailing a letter into an extraordinary underwater experience. Visitors can dive down to the postbox and send special messages to family members and friends, making the experience a memorable souvenir of their trip to Japan. The unusual attraction has gained popularity among tourists looking to combine scuba diving with a one-of-a-kind postal experience. The underwater postbox in Susami Bay is now regarded as one of Japan's most distinctive tourism attractions, offering visitors the chance to literally 'dive' into their next message.
