 By 1918, the Navy had gained approval for an "eight-six" fleet, all ships under eight years old.However, having four large battleships and four battlecruisers on order put an enormous financial strain on Japan, which was spending about a third of its national budget on the Navy.Despite this, the IJN gained approval of the "eight-eight-eight" plan in 1920 after American President Woodrow Wilson announced plans in 1919 to re-initiate the 1916 plan for ten additional battleships and six battlecruisers.
