Our last shot of the war in Japan for this part reveals neither side being able to make much progress. The minimap appears to show Nagoya being back in Australian hands, and Tokyo and Wakayama are surrounded by Aussie biotroopers. On the other hand, Osaka is even more firmly Korean, and has not suffered the effects of a siege, meaning it is bigger than the largest of the ROJ’s shrinking cities.
Kyoto appears to be likely to stay in the DPRJ, albeit probably after one extra flip from that half-health biotrooper. But Korea doesn’t have the navy anymore to exert its power further afield: at this point it’s mostly carriers remaining, although kamikaze carriers probably wouldn’t be a bad move at this point, as they would likely be replaced by something that’s not a carrier.
