Italy's best tank was the Fiat M13/40. A 47mm armed light tank that did not see service until June 1940, almost a year into the war. It had an impressive 30mm of armor capable of mostly deflecting heavy machine guns and certain auto cannons at range.
To mirror their obvious prowess in tank design, Italy gets a total of 4x armor research bonuses.
Japan produced some 75mm armed Chi-Nu's (similar in quality to a 1939 medium tank), which did enter production until 1944, but for the most part, their best tank was the 1942 Ke-Ni, a lightly armored, 37mm armed tank consistent in quality with a 1936 HOI4 light tank.
Japan gets 2x armor bonuses
None of the allies get more than a single 1x armor bonus.
USA gets none at all, despite it's quickly modernized tank program from 41'-42'.
The point of HOI4 is provide the player with ways to run a nation that differ from how they were ran historically so I am not necessarily opposed to the idea of Japan and Italy getting tank research. It's the fact that the Allies, particularly the allied majors who all historically had superior tank programs at some point in the war, get little or no research at all, denying the player from choosing a historical way to play their nation.
