Deepwater divers prepare to search inside sunken Japan tour boat for 12 people still missing
- Japan coastguard boats continued to search for the missing at sea, while police expanded their search for the tour boat that sank off the Shiretoko Peninsula
- The boat was carrying 24 passengers and two crew members when it made a distress call and disappeared on April 23 during a sightseeing trip
A vessel carrying divers trained to work at great depths arrived at a port in eastern Hokkaido on Tuesday in preparation for a search inside a tour boat that sank off the Shiretoko Peninsula last month, leaving 14 people dead and 12 missing.
The vessel is slated to leave Abashiri port late on Wednesday afternoon, with the divers expected to start searching inside the 19-ton Kazu I, located about 120 meters below the surface, as early as Thursday for anyone left inside.
Underwater drones have already been used to search inside the boat but no one was found.
The divers will attempt a special technique known as saturation diving, in which they absorb a mix of oxygen and helium so they can adjust their bodies to the level of water pressure at the depth they intend to work at.
The transport ministry’s Hokkaido bureau conducted an on-site inspection of four tour boat operators in the town of Shari on Tuesday to check their safety practices. The ill-fated tour boat was based there.
