== Description ==
<!--''In the description, the first part needs to be about the history of the creation and combat usage of the vehicle, as well as its key features. In the second part, tell the reader about the ground vehicle in the game. Insert the screenshot of the vehicle. If the novice player does not remember the vehicle by name, they will immediately understand what kind of vehicle it is talking about.''-->

The '''{{Specs|name}}''' is a premium Rank {{Specs|rank}} Japanese medium tank {{Battle-rating}}. It was introduced with the initial Japanese Ground Forces tree in [[Update 1.65 "Way of the Samurai"]], but was released once all the Rank III Japanese tanks were available to the public in the Closed Beta Test. It costs 1,600 Golden Eagles. The Chi-Nu II is essentially the [[Chi-Nu|Chi-Nu]] body with the turret from the [[Chi-To|Chi-To]], giving the tank access to the high-power [[Type 5 (75 mm)|Type 5 75 mm]].

The Chi-Nu II is a combination between two vehicle, the Type 3 Chi-Nu and the Type 4 Chi-To. It has the armour of the former, but the gun of the latter. Thus, while presenting itself as a more vulnerable body with only around 50 mm of armour, it has slightly better mobility than the Chi-To, a smaller profile, yet carries the same gun. Like the Chi-To, the Chi-Nu II should be played in a sniper-like format from a distance rather than up-close to the enemy and fighting them in close-quarters.

=== Survivability and armour ===
<!--''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpfull for survival in combat?''

''If necessary use a visual template to indicate the most secure and weak zones of the armour.''-->

== Usage in the battles ==
<!--''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''-->
Against the medium tanks, its simply getting the first shot off first as the 75 mm Type 5 cannon on the Chi-Nu could penetrate most through the front hull armour, with some levels of difficulty on the turret. Of course, for maximizing the Chi-Nu's own survival, attack from the sides and make sure the enemy is unaware of the Chi-Nu's presence.

The Chi-Nu II can meet heavy tanks, but will most likely be the 76 mm [[KV-1 (L-11)|KV-1]] [[KV-1S|series]] [[KV-1 (ZiS-5)|tanks]], which the 75 mm can easily punch through the front armour. The Chi-Nu II can still meet the British [[Churchill Mk VII]], which is impervious to the high-penetrating 75 mm from the front, so beware if caught in a frontal engagement.

=== Pros and cons ===
<!--''Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Do not use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".''-->
'''Pros:'''

* Powerful 75 mm cannon rivaling the [[T-34-85|T-34-85]] for its BR, good penetration and very low shell drop-off.
* Decent gun depression of -10°.
* Good handling, same as Chi-Nu.
* Fast and mobile.
* Narrow chassis allows access through areas inaccessible by wider tanks.

'''Cons:'''

* Chi-Nu's 50 mm armour is vulnerable to most incoming fire.
* Most part of armour is only lightly sloped, even the turret.
* Reload rate quite slow.
* Angling front armour can expose weaker 35 mm side armour.

== History ==
<!--''Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the <code>main</code> template. Be sure to include links to sources at the end of the article.''-->
===Development===
The lackluster performance of Japanese tanks in World War II called for the development of newer medium tanks in the Imperial Japanese Army. The standard tank of the time was the [[Chi-Ha|Type 97 Chi-Ha]], which has its chassis used in many expedient models to provide a bigger gun for the Japanese inventory such as the [[Chi-Ha Kai|Chi-Ha Kai]], [[Chi-He|Type 1 Chi-He]], [[Ho-I|Type 2 Ho-I]], and [[Chi-Nu|Type 3 Chi-Nu]]. Two new sophisticated tanks were also in development, the [[Chi-To|Type 4 Chi-To]] and the [[Chi-Ri II|Type 5 Chi-Ri]], both fielding the powerful Type 5 75 mm gun. However, these two tanks still needed time to iron out some design bugs, time that the Japanese did not have while being stared down by the Allied powers. To get the Type 5 gun out to their forces as fast as possible, designers sought a way to get the gun onto a vehicle as fast as possible. The solution laid on the Type 3 Chi-Nu, regarded as one of Japan's best tank since its production start date in 1943.<ref name="SenshaManualChiNuII">Sun 2017, ''[WT] Type3 Chi-Nu II''</ref>

The Chi-To's prototype models had larger turrets that were different from the main production model. Instead of wasting these turrets, the Japanese decided to use them on the Chi-Nu body. In March 1945, a Chi-To prototype turret was attached onto Chi-Nu chassis #37. This upgraded Chi-Nu, along the line of the Chi-Ha's upgrade, was informally labeled the ''Chi-Nu Kai''. The design was tested on the Irago Firing Grounds on March 19th and proved itself very satisfactory in combat roles. The final design was to equip the Chi-Nu with production model Chi-To turret to increase production levels and it was to help improve Japan's armoured forces to stand up against the Allies' might. This Chi-Nu with the production Chi-To turret was known as '''Chi-Nu II'''.<ref name="SenshaManualChiNuII" />

===War's end===
Like most of the Japanese late-war tanks developed and retained in the home island for the "final defense", the modified Chi-Nu and its counterparts never saw battle against Allied armour. Japan surrendered in September 1945, effectively ending World War II. A few Chi-Nu IIs were made before the end, but they are most likely sent to the scrap yard along with most of the other Japanese equipment with their demilitarization.<ref name="SenshaManualChiNuII" />
