Are you refering to the Japanese to try to cripple Rossiya's sovereign islands or just blockading Rossiya?
Hi Oberst,
As Thiel's stated, and given the disparity between Rossiya and Japan, I think the most sensible option for the Japanese would be an attempt to remove Rossiya's ability to make war, striking the sovereign islands. Blockading works best over the longer term and given the disparity in tech and production the worry for the Japanese would be that they are serving their fleet up to be taken out at Rossiya's leisure (also, the ongoing commitment of forces would probably sit badly with a nation that is planning - needs - massive expansion to supply their own military, unless there is a realistic prospect of actually conquering Rossiya and making Rossiyan resources their own).
As I said, it's your AU and you can have the various players do anything you want, but trying to look at it from a Japanese perspective I can't see why they'd go for the naval base when there is a much bigger prize on offer.
EDIT: Oh, and for the "blockade" stuff I was talking more about the effect on Svyatoslavovich Naval Air Base of the strike on Rossiya sovereign islands - the allies in WWII reduced Rabaul's effectiveness by preventing anything from getting to it and taking the territory around it away from the Japanese. This tactic would reduce Svyatoslavovich Naval Air Base's effectiveness by destroying the head end of the supply line, ideally. In both cases the target base ends up with no supplies, but Rabaul needed long-term dominance of the sea and the other one requires a decisive deep strike at your enemy - the second, from what I have read of WWII Japan, fits more with the mentality and is more practical for a nation at a disadvantage anyway (the IJN strategy wasn't to hold the Pacific, I think, it was to attrit and eliminate a hostile force over the course of a single strike, retaliatory or otherwise, by their enemies - which is why those win-loss ratios become so crucial)
Regards,
Adam
