TOKYO - All Japan-related crude oil tankers that had been caught up in Middle East tensions have transited the Strait of Hormuz and left the Persian Gulf, a source close to the matter said Tuesday, while four other Japan-linked vessels remain stranded in the gulf.

Data from global ship-tracking website MarineTraffic and other sources show the oil tankers, including ones operated by Mitsui O.S.K. Lines Ltd., appear to have cleared the strait by Tuesday, with some headed for Japan.
