Japan won't move until they have a chance. Without the German and Italian forces binding the RN, the Japanese see no possibility in war. That's why they made this proposal. They are outside and need an ally. The USSR is a good source for resources. But can't do much else, especially not binding fleets. For Japan it is good to let them make as much trouble as possible. A serious chance to attack is needed, but the Soviets won't be able to give it. The Japanese know that and will back down- and prepare for later.
