It is an improved model of the Type 90 main battle tank equipped by the Japanese Ground Self-Defense Force. The Type 90 tank is the third-generation main battle tank that Japan began to equip in 1990, and Type90Kai has carried out a series of modernization upgrades on this basis. The armor uses composite armor technology to improve the protection of modern anti-tank weapons, especially the protection of the tail stable shell-piercing projectile. It is equipped with a 120mm smoothbore gun capable of firing a variety of munitions, including tail-stabilized shell-piercing shells. While maintaining the excellent performance of the original 90 tank, it also adapts to the needs of the modern battlefield.

It is the third-generation main battle tank equipped by the Japanese Ground Self-Defense Force. It was designed and manufactured by Mitsubishi Heavy Industries to replace Type 61 and some Type 74 tanks. It entered service in 1990 and is known for its superior firepower, mobility and protection. Equipped with a 120mm smoothbore gun of German Rheinmetall licensed by Japan, equipped with an automatic loader, a laser rangefinder integrated in the gun's long sight, and a thermal imager, with the ability to shoot between marches and at night. The main parts adopt composite armor or interval armor, with three-proof device, automatic fire extinguishing device and laser detection and alarm device, which enhances the survivability of the tank.

The Type 87 reconnaissance and surveillance vehicle is a wheeled armored vehicle developed by Komatsu Corporation in Japan and used by the Ground Self Defense Force for reconnaissance purposes. Each division and brigade of the Ground Self Defense Force is equipped with reconnaissance teams and tank company headquarters. The Ground Self Defense Force initially used two types of wheeled armored vehicles, the US M8 armored vehicle and M20 armored vehicle, both of which were only equipped in a few cases and had a short service period. The reason is that at that time (in the 1950s), Japan's road network was poor and most of the main national highways were unpaved. As a domestic mobile wheeled vehicle, its mobility was not strong, and the budget for equipping tracked vehicles such as the Type 60 armored personnel carrier was limited to support another type of vehicle.
