The Type 1 Ho-Ni I is a Rank II Japanese tank destroyer with a battle rating of 2.0 (AB/RB/SB). It was introduced along with the entire Japanese Ground Forces tree in Update 1.65 "Way of the Samurai"


The Ho-Ni I is based off tha Chi-Ha chassis, which Japanese ground forces will be familiar with since it is featured on other japanese early tanks: Chi-Ha,Chi-Ha Kai,Ho-Ro and Ho-Ni III. Since this chassis is well known, let's describe what's new: the gun mount.


In War Thunder, Japanese ground forces have some kind of a "tradition" to mount their next turreted tank's gun on an older chassis: The Type 90 is found on the later Chi-Nu tank in a turreted format. Same thing goes with the Na-To and its Type 5 later mounted on the following turreted tanks:Chi-ToLate and Chi-Ri II(with a bonus 2-shot *autoloader*). That way, one can experiment with the amazing firepower of a decent BR 3.3 gun at BR 2.0 !

Plus, for a 75 mm gun, the Type 90 gun's HE shells have 11 mm of penetration, which is more than other guns of the same caliber such as the one equipped on a Panther D (10 mm) or a M4A2 (76) Sherman (7 mm) . This increased HE cabability is not to be ignored at such a low BR.

It fires smoke shells.

Only one flaw tatters this SPG's perfection: it has no machine gun to take out light targets and it's reload rate is quite long for this low BR (target roof armour of light vehicles).


There is many downsides to this configuration: the Ho-Ni I comes in as an open-topped SPG with only 3 crew members, with 2 of them in the superstructure, exposed to any strafing plane or back MG fire. All sorts of nasty things can rain fast on the Ho-Ni I. (For only 0.3 more BR, the Ho-Ni III is completely closed and has a crew count of 5.) From the front, beware HMGs at close ranges since 25 mm of almost flat armour is not enough to protect the crew. There is also no gun mantlet so that even a lucky MG bullet can hit either commander of gunner. Little consolation: there is extra 25 mm plates around the gun's hole, protecting most of the commander's and gunner's body with a cumulative 50 mm of armour ! At this BR, this is enough to block incoming shots from 500+ m.

Usage in the battles

The Ho-Ni I should be played like most open crew compartment, fixed gun tank destroyers, fighting from a distance from the front-lines and delivering support fire. The thin armour means the Ho-Ni I will not survive a direct confrontation with any enemy tank and will require the vehicle to obtain the fighting advantage of being able to target the enemy first to ensure any chance of victory. The Ho-Ni I should also be wary of enemy aerial attacks as the open compartment and three-man crew means that an accurate strafing fire could potentially knock out the entire crew.

At its battle rating, the worst the Ho-Ni I could face are the German Pz.IV E and British Cromwell V and Matilda Mk II. The two medium tanks have sufficient armour to withstand the 75 mm gun while the Matilda II requires precise shot in order to destroy it frontally. All of these tanks have guns able to shred the Ho-Ni I apart if they could get a bead on the it.

Pros and cons


  • 75 mm cannon is great, reloads fast and causes massive damages upon penetration.
  • Very low BR, has a good chance of being matched with lower BR tanks.
  • While at the same time will be able to match enemies on and above it's BR rather equally.
  • Mobility is decent due to being built on a Chi-Ha chassis.
  • Gun is able to effectively penetrate all tanks frontally from BR 1.0 to 3.0.
  • Similar play style as the German Marder with better gun depression.
  • Good gun traverse speed
  • Powerfull HE shell (11 mm of penetration)
  • Has smoke shells


  • Tall profile.
  • Overall armour is thin.
  • Poor cross country performance due to narrow tracks.
  • Exposed crew space makes it vulnerable to air attacks.
  • Reverse speed is abysmal.
  • Only two types of shell.
  • Only 3 crew member.
  • Rather small traverse angle


The creation of their own independent armoured division had Japan also envision an enlargement of their artillery forces. They decided to build a series of assault guns based off the Type 97 Chi-Ha chassis. One of the first of these design was the Ho-Ni I which had the Type 97 chassis fitted with a 75 mm Type 90 field gun.[1]


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
