One of the most famous helmet designs from World War II is the Type 90 helmet, which was introduced in 1930 and used by Japanese forces throughout the war. The Type 90 helmet was made of steel and had a distinctive dome-shaped design. It had a leather liner that could be adjusted to fit the wearer’s head, and it was held in place by a leather chin strap.
The Type 90 helmet provided good protection against shrapnel and other debris, and it was widely used by Japanese infantry and other ground troops during the war. It was also used by Japanese colonial troops in China and other theaters of war.
In addition to the Type 90 helmet, the Japanese military also used other helmet designs, including the Type 89 helmet, which was similar to the Type 90 helmet but had a slightly different shape, and the Type 97 helmet, which was made of fiberglass and had a more modern design. These helmets were used by various branches of the Japanese military, including the army, navy, and air force.
