During the war, Japan was using the latest technology available, such as the Type-3 Heavy Machine gun, the Wakamiya seaplane carrier, the Arisaka type 38 Rifle and Arisaka type 44 Cavalry Rifle.
The Wakamiya seaplane conducted the first successful naval launched raids. These 3 Japanese weapons would later serve in the conflict Japan had with China prior to WWII and later into WWII. The difference between the type 38 and 44 was that the 38 was bigger and heavier and used more commonly with regular infantry troops, while the type 44 was used in cavalry units
