Rising Sun Flag
The design is similar to the flag of Japan, which has a red circle in the center signifying the Sun. The difference compared to the flag of Japan is that the Rising Sun Flag has extra sun rays (16 for the ensign) exemplifying the name of Japan as "The Land of the Rising Sun". The Imperial Japanese Army first adopted the Rising Sun Flag in 1870. The Imperial Japanese Army and the Imperial Japanese Navy both had a version of the flag; the naval ensign was off-set, with the red sun closer to the lanyard side, while the army's version (which was part of the regimental colors) was centered. The flags were used until Japan's surrender in World War II during August 1945. After the establishment of the Japan Self-Defense Forces in 1954, the off-set Rising Sun Flag was re-adopted for the JMSDF and a new 8-rays Rising Sun Flag with a yellow border for the JGSDF and JSDF was approved by the Supreme Commander for the Allied Powers (SCAP/GHQ). The flag with the off-set sun and 16 rays is the ensign of the Maritime Self-Defense Force, but it was modified with a different color red. The old flag is darker red (RGB #b12d3d) and the post-WW2 modified version is brighter red (RGB #bd0029).
