I think the Aegis and Furuno radars have been explained to death on NHK this evening. Here is why:
MINAMIBOSO, Chiba — A Maritime Self-Defense Force (MSDF) destroyer collided with a fishing boat off the coast of Chiba early Tuesday, splitting the fishing boat in two and leaving a father and his son missing, officials said.
The 7,700-ton MSDF Atago destroyer collided with the Seitokumaru tuna trawler about 40 kilometers south-southwest of Nojimazaki Cape in Minamiboso shortly after 4 a.m. on Tuesday.
The hull of the 7.3-ton fishing boat was smashed in two, and two people on board the vessel, identified as 58-year-old Haruo Kichisei and his 23-year-old son Tetsuhiro, are missing.

So was someone asleep at the radar? Or was it turned off in an effort to save electricity?
It appears to me that the fishing vessel failed to give way since under the rules of the road it was the vessel under obligation to change course. Or they did not respond to bridge to brige communications.
Correction. Talking to my black shoe friends it appears the JMSDF was the burdened vessel. Then again, as happens in many of the Asia ports is that the little fishing boats dart in and out and do not follow the traffic scheme in and out of the harbor.
Or was someone relying too much on the wonderfulness of modern technology and not keeping both a sharp lookout and a tight moboard plot? And concur too on the proclivity of fishing boats to go their own way – that is universal. The crabbers in hampton roads were notorious about that…
