The War Thunder team is proud to introduce the Ho-Ri, Japan’s first Rank 4 tank destroyer in the Japanese Ground Forces tree.
In this article, we will discuss the development of the Japanese Ho-Ri Tank Destroyer. With permission to post newly licensed documents dug up from the National Archive of Japan, we will review the history and production of Japan’s last tank destroyer of the war.
As the war progressed in the East, it became increasingly evident that Japan’s infantry-support based tank doctrine would not suffice against the growing threat from the United States. Aware of the American M6 Heavy tank, Japan decided to carefully review German tank doctrine. This new policy focused on the development and deployment of a common medium tank with stronger armament, which would in turn be supported by tank-destroyers with high-caliber weaponry.
Development of the Ho-Ri began in late 1943, using the chassis of the Type 5 Chi-Ri as the base for development. Japan’s 4th Technical Institute of Research understood that the Chi-Ri’s un-sloped frontal hull offered little protection against enemy anti-tank fire. A key focal point in the design of the Ho-Ri was the decision to angle the front armour plate to 70 degrees. The concept was presented to the Ministry of War in early 1944 in the form of a wooden mockup.
Following the presentation, the Ho-Ri was approved for construction, and in August of 1944, the first prototype had been constructed. Weighing in at approximately 35 tons, the tank had a speed of 40 kph using a Kawasaki Water-cooled V12 Engine, identical to that of the Chi-Ri medium tank, with a power output of 550 horsepower. Armour layout was also kept at similar specifications. Mounting an experimental high velocity 10.5cm tank gun, with an assistant loader mechanism, it achieved 150 millimeters of penetration at a range of 1,000 meters during trials. However, the Japanese Weapons Administration required more, and the gun was later revised.
The Ho-Ri prototype was approved for production for 1945, and was to be officially adopted into service under the designation Type 5. The production model of the Ho-Ri increased the thickness of the front hull plate to 120 millimeters. To compensate for the added weight of the increased armour an experimental Kawasaki V12 engine with an output of 1,100 horsepower was added.
Formal production of the Type 5 Ho-Ri began in January of 1945. By March, a total of 5 Ho-Ri tanks had been produced; further production of the vehicle was halted by American bombing raids. These vehicles were eventually destroyed or disposed of in deep lakes shortly before Japan’s surrender to U.S forces in order to prevent their capture and evaluation by U.S occupation forces.
The Ho-Ri is the first tank in the Japanese Ground Forces tree to be armed with a 10.5cm gun. Experienced users of the 7.5cm Type 5 will be glad to know this new tank destroyer is armed with an even deadlier cannon. With its APHE shell, it has an outstanding performance of 200 millimeters of armour penetration at 1,000 meters. Its accurate cannon makes this tank a force to be reckoned with on the field.
Experienced players of the Japanese Ground Forces’ vehicles may rest at ease knowing that the Ho-Ri, like its counterparts, offers extreme gun-depression for its commanders to use to their advantage in battle. Boasting a full ten degrees of gun depression, the Ho-Ri can use hills to its advantage when engaging enemy targets!

To accommodate the lower superstructure silhouette, the Ho-Ri has a unique mechanic: an elevating hatch which allows the gun to depress and aim at enemies while protecting itself. Players who have have already familiarised themselves with previous Japanese tank-destroyers will be most eager to get their hands on the Ho-Ri.
This machine will surely be a well appreciated addition to the Japanese Ground Forces tech tree, but it doesn’t stop there. Prototype version of the Ho-Ri will be included in Update 1.71 as Rank IV premium vehicle, we also going to add production version of the Ho-Ri as regular vehicle in the Japanese tech tree in our upcoming updates.

Hey Blockhaj It’s off topic since it deals with WoT and not WT but the tier 5 tank destroyer I was talking about awhile ago I found some details about it on the following page I don’t know if you still care but it was tough just trying to find an image and details of it so here
half way through the page on kikiri’s post should have some basic info and picture
I do not understand why this is not wot yet.
Cuz wg cant get their shit together.
Alright, you put together the tech tree leading up to wherever the hill this thing would sit.
WG basically just said that because the chinese TDs were a “Hit” they will introduce the Japanese TD’s at some point…
This is why i recently left wot. they would rather make make-believe tanks than fix the game or real tanks. Wt is much for diverse for obvious reasons. I wish i moved sooner;)
In WG’s defense, they do claim to be working on Japanese tank destroyers
I’m already anticipating all the ballistic antics those little plates forward and behind the exhaust are going to cause…
WG doesnt find enough income in japanese TDs so just “fck players buy tanks and stfu”.
looks like a japanese sturer emil :/
but srsly i want to see it on WoT
That’s actually incredibly easy. Japan has an excess number of TDs that WG can use. Most of them are based off of tanks already in the tech tree, so coming up with module filler really shouldn’t be that difficult. Just one possible tree:
II: Ho-Ru (47mm, Ha-Go chassis, Prototyped)
III: Ku-Se (75mm, Ke-Ho chassis, Blueprint Proposal)
IV: Ho-Ni I (75mm, Chi-Ha chassis, Production)
V: Ho-Ni III (75mm, Chi-Ha chassis, Production)
VI: Na-To (75mm, tracked carrier chassis, Mid-Production)
VII: Ka-To (105mm, Chi-To chassis, Prototyped)
VIII: Ho-Ri I (105mm, Chi-Ri chassis, Blueprint Proposal)
IX: Ho-Ri Prototype (105mm, Chi-Ri chassis, from initial trials)
X: Ho-Ri Production (105mm, Chi-Ri chassis, final version)
Some additional premium candidates:
IV: 120mm Naval Short Chi-Ha (Production)
V: Ji-Ro (105mm, Type 95 Heavy chassis, Prototyped)
VI: Experimental 12cm SPG (120mm, Type 95 Heavy chassis, Prototyped)
VIII: Ho-Ri II (105mm, Chi-Ri chassis, Alternate Blueprint Proposal)
Experimental 15cm SPG (150mm, Chi-Ha chassis, Unsure if Real?)
Chi-Ri TDs (75mm, a variety of casemate-d Chi-Ri designs)
If ignoring a potential Japanese SPG branch, there’s even more to work with:
Ho-Ni II (105mm, Chi-Ha chassis, Production)
Ho-To (150mm, Ha-Go chassis, Prototyped)
Ho-Ro (150mm, Chi-Ha chassis, Limited Production)
120mm Naval Long Chi-Ha (Prototyped)
