Passed Midway and still no boats to sink?

Here's a basic map showing major Japanese wartime convoy routes. The reason you're not seeing any Japanese merchants even past Midway is there is simply nowhere out there in that vast ocean desert for them to sail to. Most of Japan's conquests and badly needed resources were to the south and in China. So that's where the shipping routes go.
