The Battle of Nagashino (長篠の戦い, Nagashino no Tatakai) was a famous battle in Japanese history, fought in 1575 at Nagashino in Mikawa Province (present-day Nagashino, Shinshiro, Aichi Prefecture). The allied forces of Oda Nobunaga and Tokugawa Ieyasu (38,000) fought against Takeda Katsuyori's forces (15,000) and the allied forces won a crushing victory over the Takeda clan. As a result, Oda Nobunaga's unification of Japan was seen as certain. In recent years, the battle has increasingly been referred to as the Battle of Nagashino and Shitaragahara (長篠・設楽原の戦い, Nagashino Shitaragahara no Tatakai). The battle started with an offensive over Nagashino Castle, followed by a battle at Shitaragahara, about 4 km to the west of the castle. Traditionally, the siege of Nagashino Castle by the Takeda forces and the decisive battle between the two main armies were regarded as a series of manoeuvres, and the battle was called the "Battle of Nagashino" after Nagashino, the name of a wide area in the region. However, if the emphasis is on the actual location of the battle (where the final battle took place), it is more appropriate to use "Battle of Shitara-gahara".
