Japan opened in 1660

[DuQuense]

OTL a lot of the British Empire in the 19th and 20th Centuries was based on Britains control of lots of the "Little Rocks" St Helens, Bemuda, Falklands, Dieigo Garsia, etc.

This played into the Design of British ship at the turn of the century. British Ships had less bunkerage that the US ships, as Britian knew it had control of Bunkerage points.

Here a modernizing Japan, building European style [Better than Junks, for Distance] Warships, may try the same thing.
An Anglo/Japanese war in 1790 over control of the Falklands.

Part of the issue was that the Shogunate forbade Japan from building a complex navy IOTL.

The dutch fleet opened Japan three century before...

Why would the VOC do such a thing? It had nothing to gain by it and quite a bit to lose, Japanese silve and copper financed a good part of its Asian operations.
The VOC was a monopoly enterprise which did not like competition.
At all.
Belief in the virtue of free trade was a 19C thing
