I just took a look at the 1465AD save. Here are some observations: Japan has Fukushima again, apparently. Japan also has rubber near Echizen, on the island near home. We have oil near 30 already hooked up. We need to trade some lux to Joan and Cathy. Liz is down to 2 towns, and likely to be down to just Reading soon. Japan has pop of 162, while China has 107 (we have 664). It appears that Japan is on the offensive against China, as there are Japanese cav visible but no Chinese troops. I'm not sure that any special attention will be needed. A RoP with Japan may be helpful to beat down Mao a bit.
