Japan saw the Use of tanks pretty limited.
They could only use tanks on China, Japan and a couple of Islands.
Unlike Germany, USSR, UK, USA, etc, they decided to put more effort, if not all, on building a Navy.
To win the Pacific War, you need a navy, and a strong one. Japan had enough Ports and Companys that could build Ships maintain and keep producing.
Also they had a pretty decent airforce, with good Companys making them.
Tanks in china? well, field a thousand or something yes, you'll need tanks there, since the Chinese doesnt have any tanks to face the Japs in a Kursk Style battle, Heavy guns ,etc.
Philliphines? yes, well, kinda, you'll need a Thousand or something.
Burma? Hell no!
Sigapore? YES!, thats why japan won the battle for the entire peninsula. There were wooden bridges, and the allies dindt expected tanks there, and the Light weight of the IJA tanks made it across bridges, striking fast.
The Japs developed heavier tanks in late war, some good tanks and others were still shitty.
I remember the japs used to have a pretty good Tank Destroyer, enough to bring down the Sherman..
But yeah, they Focused, on land, more on infantry.. and they had good one!
