Why Germany could not send its surface fleet to Japan

What if Germany sent most of the Kriegsmarine surface fleet to the Pacific to aid Japan after Bismarck was lost?

The ships would probably be intercepted and destroyed before reaching Japan, with British forces able to attack along the long route.

Sending the German surface fleet to Japan after Bismarck's loss would expose it to British interception throughout the voyage. The proposed route passes through the North Sea and the North and South Atlantic before reaching the Pacific. A breakdown would leave the ships particularly vulnerable, while British submarines, destroyers, and battleships would have opportunities to attack them. The assessment is that the German ships would be destroyed on the way.
