Battotai can also called the Review March in the Self Defense Force.

Under the terms of the Treaty of Mutual Cooperation and Security between the United States and Japan, United States forces stationed in Japan were to deal with external aggression against Japan while Japanese forces, both ground and maritime, would deal with internal threats and natural disasters. Only after the outbreak of the Korean War did MacArthur authorise Prime Minister Shigeru Yoshida to establish a 75,000 strong National Police Reserve. The next expansion came in 1952, when as a compromise in the face of U.S. calls to build up an army of 350,000, the National Police Reserve was re-titled the National Safety Force and expanded to 110,000.

In 1954, Prime Minister Yoshida impelled the Diet to accept the Defence Agency Establishment and the Self-Defence Force Laws, which explicitly authorized the forces to ‘defend Japan against direct and indirect aggression, and when necessary to maintain public order.’[5] On July 1, 1954, the National Security Board was reorganized as the Defense Agency, and the National Security Force was reorganized afterwards as the Japan Ground Self-Defense Force (Army), the Japan Maritime Self-Defense Force (Navy) and the Japan Air Self-Defense Force (Air Force), with General Keizō Hayashi appointed as the first Chairman of Joint Staff Council—professional head of the three branches. The enabling legislation for this was the 1954 Self-Defense Forces Act [Act No. 165 of 1954].

That year the actual strength of the Ground, Maritime and Air Self-Defence Forces reached 146,285, armed mainly with U.S. World War II vintage equipment.[6] At least up until the 1970s, the Ground SDF was not built up to the point required to defeat an invasion attempt from the north – informed officials estimated that while ammunition provisions were officially said to be enough to last for two months, in actuality it would be used up in a week or less.
