Let's say the Japanese became more aggressive, and send their own deployment of forces after Hawaii becomes governed by the Provisional Government. After a military crisis the Japanese and Americans make a deal, leaving Hawaii as neutral territory and to allow a referendum of the Hawaiians to decide whether or not the Kingdom be restored. With overwhelming majority it is, and the Provisional Government goes to exile.
With a POD around or after 1890, keep the US from annexing Hawaii, either from an anti-Annexation President or anti-Annexation Congress, or anything else.
WWI assumedly will be in the early- to mid-1910s.
