Site of Special Attack
121st Shin'yō Squadron
Hososhima Base

Hososhima Shin'yō Monument
Hyūga City, Miyazaki Prefecture

The wooden post (see left side of photo) and explanatory signs were set up in 1993 to remember the 121st Shin'yō Squadron stationed near the entrance of Hososhima Harbor. They are built on the side of a hill at the former site of a tunnel used to store shin'yō explosive motorboats.

The right sign has a drawing of a shin'yō motorboat with an enemy warship, the boat's intended target, in the background. The sign to the left of the drawing gives the following history of the 121st Shin'yō Squadron:

Here in this area of Hososhima and Mihokogaura is the site where 188 members of the 121st Shin'yō Squadron under the command of Lieutenant Junior Grade Kota Fujioka constructed a base and dug tunnels for 25 shin'yō boats that were Navy tokkō (special attack) weapons. They did this in May 1945 when the Pacific War situation became grave in order to save the country in its time of crisis through their deaths. They devoted themselves to training day and night and waited for their time to sortie.

The Model 5 shin'yō boat was a motorboat made of plywood with a length of 6.5 meters. It carried 250 kg of explosives in the bow in order to carry out a body-crashing attack by itself at high speed into an enemy warship. The 54 crewmen who were stationed here included the squadron commander, boat leader, and young men from only 15 to 18 years old who had trained at the Mie Naval Air Group Otsu Hikō Yokaren (Preparatory Flight Training Program). In addition, base workers, maintenance workers, and other squadron members who worked at headquarters provided valuable support to the crewmen.

Later the squadron moved to Kajiki Base (Kagoshima Prefecture). Not having the opportunity of time, the squadron ended the war with its ardent desire to no avail. Since then nearly a half century of time has passed. Now having the earnest support of local residents, we erect a post here at Hiratokobana to commemorate from the heart this war site on top of one of the boat tunnels. This monument conveys our sincere desire for eternal peace.

The Hososhima Shin'yō Monument is located on the slope behind the restrooms at the end of the parking lot for Kuroda no Kashin, a small island in Hososhima Bay that can be reached by a narrow land bridge during low tide.

The sign near the ground to the left of the sign with the primary historical information gives the words of the Shin'yō Corps Song composed by Hajime Onda at Kawatana Training Base on February 23, 1945, and the words of the 35th Arashi Butai (Unit) Song composed by Jirō Nomura.

The monument site has not been well maintained. For example, there is a tattered Japanese flag on a pole behind the information signs. The wooden post that says "Site of Special Attack 121st Shin'yō Squadron Hososhima Base" is leaning. There is no path to the monument, so someone wanting to read the information signs needs to climb up the slope to get there.
