If Hawaii is a British colony, and The British allow The USA a naval bast at Pearl Harbor as part of Lend-Lease or by some treaty, then I can easily see a Japanese attack on Pearl Harbor bringing The US directly into the war as in OTL, and it allows Japan to hit two birds with one stone.
Japan was an ally of Nazi Germany. Germany was at war with England. The US is an ally of England and has a major naval base on The British Colony of Hawaii. Japan attack the USA by hitting America's base at Pearl Harbor, and by hitting a base in Hawaii Japan also is attacking England who is the enemy of Japan's ally.
In this scenario Japan might even have more incentive to attack The US Naval Base at Pearl Harbor. Hawaii as a British Colony might force Brittain to fight more of a two theater war both Europe and Pacific. Not sure what this does to the war in Europe.
