Could Japan seek a decisive battle against the reinforced Eastern Fleet?

Would the reinforced British fleet give Japan an opportunity for the decisive battle it wanted?

It could, but Japan would have to replenish and commit a suitable force while the Allies strengthened Singapore and its surrounding defences.

Destroying the concentrated British fleet could appear to remove the remaining major Allied naval obstacle in the region. The imagined destruction at Pearl Harbor would itself exceed the operation's intended result, so the next decisive battle would require a fresh decision and preparation. Japanese ships would need replenishment before another major commitment. Meanwhile, an indispensable Singapore could receive resources on a scale compared with Malta. British night-fighting methods and British and American submarines operating from the base would complicate the Japanese approach.
