Those are some of the longest rivers in Hokaido, which would suit the expected or perceived importance of the ships, after all.
As for how to arrange them, I'd divide Kido Butai in three CarDivs, with 2x CV and 1x CVL each, and would add the two CLVs to the CVE force. Locations... your choice





Maybe CarDiv 2 (2 CVs and CVL/CLV) is in SRA while the remaining CVL and/or CLV are with KB. These 2 CVL/CLVs break off after Pearl to support Wake invasions and then Gilberts, if Japanese players wants to. This would reflect the divided desire of the IJN to have forces in the SRA to seize oil and Yamamoto's wanting to hit the US Pacific Fleet.
