Tank project, last version was mainly an massively enlarged type 5 Chi-Ri chassis with a weight of 120 to 140 t. Armed with a type 5 105 mm tank gun and a type 98 20 mm aa-gun in a cupola on top plus a Shinhoto turret with a type 1 47 mm tank gun and a 7,7 mm tank MG turret on the bow. The vehicle only reached early prototype stage. There are rumors that a prototype was tested in summer 1945 in Manchuria but nothing more than rumors.

Maybe an early prototype of the O-I project but most probable nothing more than a rumor.

There were quite a lot of late-war projects from which (following Taki) , the type 5 tank Chi-Ri, the type 5 tank destroyer Na-To, the type 5 tank hunter Ku-Se, the type 5 tank destroyer Ho-Ru, the type 5 light tank Ke-Ho and the 120mm SPG Ho-To reached prototype stage and the type 4 tank Chi-To became ready for production (200 were ordered for late 1945 before surrender).

Yours

Hi.

In mid 1945 the japanese tank designers and producers were busy developing the type 4 Chi-To and Type 5 Chi-Ri with a massive lack of ressources (tanks were low priority)

At surrender there were only plans to develop a tank hunter (Ka-To) and a tank destroyer (Ho-Ri) both armed with the type 5 105 mm tank gun plus up-armouring the Chi-Ri to up to 135 mm frontal armour in 1946 ("type 6" = 2606 indicates the Jimmu calendar year in which the weapon system was officially adopted, Jimmu calendar started 660 BC)

Yours

tom! ;)

Not sure, but maybe it's O-I turret. Photo taken on the Far East shortly after the war.

The Japanese original tank type 89 was used in Chinese front and Pacific front before and during WWII. This one is restored By Japanese Self Defence Army in 2007 at Tuchiura wepon scool near Tokyo as an educational technical method.

We saw it at the base day in October 2007 and it runed again in 15th November 2008. It's an important Japanese histrical thing,we think it.

As I just have the book from Ferdinand M. von Senger und Etterlin "Die Kampfpanzer von 1916 - 1966"
at hand, I'll post some drawings of Japanese tanks. The type 3, 4 and 5 remained prototypes, only.

Actually some 66 of the Type 3 were built. The Type 4 only had 6 examples (I believe some of those were prototypes) and the Type 5 was an unarmed prototype.

http://sensha-manual.blogspot.ie/2017/03/theorem-on-newly-discovered-tanks.html

In this new proposed theory, every spot in the Iroha classing system falls into their proper order up until the 1944-1945 gap where many tanks were scrapped and remain unknown.

Chi-I: (Medium First) Tank “A”
Chi-Ro: ( Medium Second) Tank “B”
Chi-Ha: ( Medium Third) Type 97 Chi-Ha
Chi-Ni: (Medium Fourth): Type 97 Chi-Ni
Chi-Ho: (Medium Fifth) Type 98 Chi-Ho
Chi-He: (Medium Sixth): Type 1 Chi-He
Chi-To: (Medium Seventh): Type 4 Chi-To
Chi-Ri: (Medium Ninth): Type 5 Chi-Ri
Chi-Nu: (Medium Tenth): Type 3 Chi-Nu

Ke-I: (Light First) Unreleased Tank*
Ke-Ro: (Light Second) Unreleased Tank*
Ke-Ha: (Light Third) Unreleased Tank*
Ke-Ni: (Light Fourth) Type 98 Ke-Ni
Ke-Ho: (Light Fith) Type 5 Ke-Ho
Ke-He: (Light Sixth) Currently Unknown
Ke-To: (Light Seventh) Type 2 Ke-To
Ke-Ri: (Light Ninth) Type 3 Ke-Ri
Ke-Nu: (Light Tenth) Type 4 Ke-Nu

Ju-I: (Heavy First) Type 96 Heavy*
Ju-Ro: (Heavy Second) Type 97 Heavy*
Ju-Ha: (Heavy Third) Mitsu-104*
Ju-Ni: (Heavy Fourth) Ishi-108*

* = Tanks currently not publicly available. Kept private with David Lister and I until his book, which was recently contracted, is published.

Sorry, he didn't give specific details on that, though based on a reply of his in the comments section, it's likely to be sometime around mid-May at the earliest.

Not a problem, just easier to take in that's all.
