The Type 91 Heavy is a Japanese tier 3 heavy tank.
Development of the Type 91, the three-turret 18-ton Japanese tank, started in 1927 and was completed in 1932. The vehicle never entered mass production. Only one prototype was built.
The Type 91 Heavy is the lowest tier Heavy tank in the game and also the earliest heavy tank in Japanese Heavy line. But, Do not let its "Heavy" class trick you - its "Heavy Armor" is extremely thin (Even some tier 1 tanks have better armor thickness than this tank!). It's also large and slow, which makes it very vulnerable to enemy fire. However, this tank offers derp gun that is powerful enough to one or two shot any tank in the same tier (assuming you can hit or penetrate) and a top gun which has monstrous penetration and DPM for its tier.
The Type 91 Heavy marks the end of its Japanese heavy line.

Player Opinion
Pros and Cons
Pros:
- Stock gun's HE rounds offer more penetration than AP rounds, yet they deal enough damage to two-shot any tank in the same tier.
- Very powerful top gun, combining good damage, penetration and rate of fire
- Fairly small turret with good gun depression
- Tied with British Medium MK.III for second highest HP pools in Tier 3 (280)
- Very fast grinding; It doesn't need new treads to equip heavier equipment expect top gun, and only has one avaliable turret. You can just spam HE on enemy and get past this tank in no time.
Cons:
- Despite being classified as Heavy Tank, its armor is weaker than some of tier 1 LT. Even HE rounds from your own stock gun would penetrate for full damage.
- Hull surfaces are mostly flat so don't expect to bounce anything.
- Very slow; very large; very poor view range.
- Awful accuracy on both guns
- Front machine gun turrets limit forward gun depression
- Top gun had fairly expensive research cost, is too heavy for stock tracks and is not used on the next tier up. However, it is shared with other low-tier Japanese tanks and can be unlocked by them.
- Very weak ammo rack gets blown up often; factoring in generally poor gun handling makes this a disaster.
Performance
The Type 91 has a reputation for being one of the worst tanks in the game, and will do everything possible to live up to this reputation. The stock gun is horrific, struggling to penetrate other heavy tanks (except other Type 91s), with poor accuracy and a reload time which will feel like an eternity. Use of HE ammo is recommended as it actually has higher penetration than the standard AP round; even if it fails to pen it may gift you a small amount of damage as consolation. HEAT rounds offer vastly improved penetration and these should be considered mandatory for players looking to deal damage using the stock gun; bear in mind that this can be very expensive, especially for a low tier tank, as you may need to use quite a few.
Think of the Type 91 as a medium tank with a high hitpool and lower speed. You will need that hitpool because you are an artillery player's dream, and using the stock gun, you are simply a mobile XP booster for enemy heavies. Do not ever rely on your armour even when angled: a piece of paper held at a diagonal angle is still a piece of paper. Do not under any circumstances engage tanks with autoloaders such as the Panzer I C or the Cruisers III and IV.
Things improve markedly for those who persevere to the second gun. It is very good at taking out same and lower tier targets and in higher tier battles can even scratch tier 5's. Bear in mind that if you mount equipment, your stock tracks simply cannot bear the weight of the second gun, so bear this in mind if you decide to use free XP for the gun.

Historical Info
Despite being a heavy tank, the Type 91 had rather thin armor - only 20mm at the most. This was thought to be sufficient protection at 50 meters from the 37mm weapons of the period, such as the French SA18.
The tank had a complicated parallelogram suspension of with two pairs of road wheels per leaf-sprung bogie. There were 17 road wheels per side, giving it a total of 34 road wheels. It shared this type of suspension with the Experimental Tank 1. The engine was a BMW 6-cylinder gasoline engine with 224 horsepower, an improvement over the Experimental Tank 1's Mitsubishi 8-cylinder gasoline engine with 140 horsepower. This gave the Type 91 a top speed of 25 kph, compared to 20 kph of its predecessor.
The Type 91 had a length of 6.30 meters, a width of 2.47 meters, and a height of 2.57 meters. Its total weight was 18.0 tons, giving it a power-to-weight ratio of 12.44 horsepower/tons.
The Type 91 passed its trials and fulfilled the requirements of its design, but was not accepted for production. This was due to the Japanese Army's decision to build more light tanks as opposed to fewer heavy tanks. The work done on the Type 91 was later incorporated into the Type 95 heavy tank.
The last known photograph of the Type 91 indicates that, after being rejected for production, it ended up in a scrapyard where it remained until after World War II, when it was found by Americans.

Historical Accuracy Errata
* The Type 91 is missing the 57mm Type 90, which the vehicle originally had before it was replaced with the Type 94 70mm. It never had the the 47mm gun, which was developed after the project was cancelled.
- The Type 91's weight was historically 18 tons. However, it weighs 20 tons in World of Tanks.
