Här är wikipedias åsikt:
Beginning in April 1917, Japan, an ally of Great Britain, sent a total of 14 destroyers to the Mediterranean with cruiser flagships which were based at Malta and played an important part in escorting convoys to guard them against enemy submarines. The Japanese ships were very effective in patrol and anti-submarine activity.[6] However, of the nine Austro-Hungarian navy submarines lost to enemy action, five were sunk by Italian navy units (U-13, U-10, U-16, U-20, and U-23), one by Italian and French units (U-30), one by Royal Navy units (U-3), while none were sunk by the Japanese navy, which lost one destroyer (Sakaki, torpedoed by U-27).

Det tycks alltså vara litet fler än de sex jagare varjag talar om, och då talar vi ändå bara om insatsen i Medelhavet. Däremot sänkte de visst ingen ubåt.
Vi kanske skall flytta det här till en egen tråd.
