Kongou appear quite frequently in World 3, 4, which have several easy maps like 3-2A, 4-1. If you really need it early on, 2-2 Boss node also has Kongous as well as first node of 2-4. 3-2, 4-1 farming is the easiest way to get them though.

Sendai appears all over the place. They are basically every map besides 1-4. There isn't a need to try a specific map to obtain it.
