Just always wanted to know the plausibility. I had the Dutch winning the Anglo-Dutch War. Any other ideas
That's not actually too implausible. Japan was very backwards for a while, at the same time that the Dutch had influence and holdings in Eastern Asia, such as Taiwan.
The Dutch even had a trading colony in Japan, on the island of Dejima.
But if you really want to increase Dutch influence in Japan, then preventing the annexation of the Netherlands by France under Napoleon will help a lot more than just making the Dutch defeat the British.
