Alright, let's say that sometime in the 1840s or early 1850s, some official gets it in his head to open up Japan to trade, if after 1850 assume Perry never went. Assuming, as OTL, that the Japanese resent this foreign interference, a resistance movement would spring up and the EIC would crush it using Indian and Japanese troops in the pay of the Company. The Emperor remains a figurehead and someone more pliable and more pro-British is appointed to the post of Shogun.
Now, assuming that the Sepoy rebellion still happens, possibly including continued resistance in Japan, what would be the fate of Japan once the EIC's powers get limited by the crown? Would Japan become a Princely State of sorts? Would direct colonization be worthwhile?
Might there be increased Japanese immigration to Canada and possibly Australia and New Zealand? How would those immigrants affect the cultures of those lands, and how would those lands affect them? How would Japan being under British rule, of one sort or another, change its culture?
