  • 4 х 7.7 mm Type 97 machine gun (750 rpg = 3000 total)

Usage in battles

Unlike most Japanese aircraft, the J1N1 can take quite a lot of punishment. As a twin-engine fighter/interceptor/attacker, it has the ability to remain in operation even flying on only one engine and with partial wing missing. While there is no real protection for its fuel tanks, it is less likely to catch fire when compared to other Japanese aircraft at its battle rating. If playing Realistic Battles, it is battle rating is slightly higher than arcade, but its forte is really in arcade battles at its battle rating. Its bomb load is relegated to smaller bomb sizes, but at the battle rating, it is enough to take out a few ground targets. The autocannons and machine guns on the aircraft are sufficient to perform strafing runs on lightly armoured vehicles. The J1N1 flying low in AB can be a real distraction for the enemy team, keeping them away from the objectives of destroying ground targets. None of its weapons cannons are very powerful and its ammo count is quite low, but in arcade battles that is not much of a problem with in-flight reloadable ammunition when you run out. For quite a large aircraft, it is very manoeuvrable, and the "ace up its sleeve" is the rear-facing turrets, each with two 7.7 mm machine guns and unlike other fighters and bombers at its battle rating, the rear gunners are enclosed within the aircraft and not exposed to stray bullets. Enemy fighters on the tail of a J1N1 often find they suffer critical damage or are shot down while the offensive guns are trained on oncoming aircraft or ground targets. The play style is neither "Boom & Zoom" nor "Dog-fight", but rather to fly low and drag the enemy onto the tail of the J1N1. In arcade battle, enemies will sometimes try to ram the J1N1, in an attempt to knock off a wing, but it will continue to fly, often losing only the wingtip.

This aircraft is less useful in realistic and simulator battles mainly due to its low ammo count, but the characteristic play style mentioned before could prove almost as rewarding and it can take quite a bit of punishment before being destroyed.

Pros and cons


  • Quadruple 7.92 mm defensive guns in a dangerous tight array
  • Fairly good speed
  • 8.5 mm of armor in pilot's seat
  • Good maneuverability
  • Two engine design for extra Survivability.


  • Beaten in turn fights by some aircraft
  • Limited ammunition for all weapons
  • Lack of protection around fuel tanks, engines, and gunner
  • A single gunner man all four guns. When hit, all four weapons stop working
  • Slightly-lacking climb rate for uptiers.
  • Offensive 7.92mm struggle to down aircrafts effectively


Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).


Excellent additions to the article would be video guides, screenshots from the game, and photos.
