It wasn't in the open sea, the area was crowded

Map of the collision

100 miles or so off the SE coast of Japan is most certainly open seas.

“crowded” in maritime terms means there’s a ship every few miles...or 20.

“It wasn’t in the open sea, the area was crowded”

There’s always a lot of traffic in that area.

Surely it wasn’t a rendezvous.

That map is so wrong.

Collision is the faint dot south of Oshima island in Tokyo Bay.
