is there any reason why ka-mi doesn’t have floats although ka-chi does? In addition, he can swim without them, which is impossible and strange in his case.
I think adding them is not difficult, the creators are just lazy. I’m counting on your opinion on this matter
There are two main ways to make a tank amphibious. One is to attach floats to a standard tank, and the other is to make the armor thin and the hull large. The Type 2 Ka-Mi was a light tank with a large hull and detachable floats. This gave it reserve buoyancy and seaworthiness, allowing it to launch from submarines offshore and travel long distances over rough seas to surprise-land on enemy islands.
Ka-Mi does not need pontoons unless they are sailing long distances in rough seas. There is information that a variation of the Ka-Mi with the pontoon attachment part omitted was produced for training purposes. As an example, this is a photo of what appears to be an early prototype with a metal lid attached to the pontoon attachment section.

As a policy of Gaijin, tanks that require additional parts to obtain amphibious capability are not given amphibious capability. When Ka-Mi was introduced in War Thunder, there was a lack of historical sources on whether it could float without pontoons, so it was implemented without pontoons and for a while Ka-Mi drowned in water.
ok, thank you for the rational and factual answer
but why did ka-chi get floats then?
There’s still hope that in the future they’ll give them to ka-mi too
