Japanese Defense Ministry Says China Did Not Fire Warning Shots at Ship that Mistakenly Crossed into Chinese Territory
This was a pretty big screw up by whoever was captaining the ship:

Japan’s Ministry of Defense has denied a Japanese media report this week that Chinese naval vessels fired two warning shots at a Japanese warship that sailed into China’s territorial waters last year. Japan Maritime Self-Defense Force destroyer JS Suzutsuki on July 4, 2024, inadvertently sailed within 12 nautical miles of the coast of Zhejiang province, Kyodo News reported at the time.
The Japanese destroyer was monitoring a live-fire exercise by Chinese forces in Hangzhou Bay, according to the report. After repeatedly warning the destroyer to change course, Chinese vessels fired two warning shots — one before it entered territorial waters and another after it crossed into the area, Kyodo reported Sunday, citing unnamed diplomatic sources.

Well, it was probably an incompetent CO who was not doing his job:
From what I was reading apparently they did not have some system on that would of showed where the Chinese boundary begins. Definitely a big screw up that the Chinese can point to the next time they cross into Japanese waters with one of their ships.
I agree GI; but the guy said he didn’t know where his ship was…
After that, he should not be trusted with another ship… Or even a berth in Supply.
