Matthew Perry ended Japan's Isolation when the US sent him to Japan.
Japan's island location played a role in its development thanks to shipping trade routes
The mountains of Japan and the location of Japan helped lead to some isolation.
Japan's two-and-a-half-centuries of self-imposed isolation resulted in an increase in domestic trade and agricultural production. The shogunate imposed this policy of isolation in order to remove the colonial and religious influence of Spain and Portugal.
They feared Europe was using religion to gain political influence.
Japan got little influence and input from the outside world so that gave it a chance to develop based on its own culture, traditions, customs and views. Hope this helped!
