Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Armaments

Offensive armament

The Ki-61-II Otsu Kai is armed with:

• 2 x 20 mm Ho-5 cannons, nose-mounted (250 rpg = 500 total)
• 2 x 12.7 mm Ho-103 machine guns, wing-mounted (250 rpg = 500 total)

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Good turn
• Good energy retention when manoeuvring
• Lower wing loading than its Allied opponents, allowing smart use of vertical manoeuvres at medium altitude
• Easy to learn MEC with
• Can reach >500km/h IAS at sea level and with good use of MEC
• Near-infinite WEP with MEC
• Quite average in all aspects as a fighter

Cons:

• Doesn't climb very fast
• Overheats quickly without MEC
• Ailerons compress seriously above 550km/h
• Faces many superior planes in an uptier - weaknesses of the enemies must be exploited to defeat them

History

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

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