093B surfaced to show flag and face so the eye can see and take photo, thats not giving acoustics data, acoustics data is under water and thus "acoustic" because you can't see underwater, have to hear, you are wrong on your conclusion. Yes surfaced to show, like a tourist likes to carve in trees showing they were there

Acoustics data is unconfirmed. Submarines have ways of creating extraneous noise like stealth aircraft carry Luneburg lenses.
The rest of the statement is likely. The sub surfaced in the vicinity of Diaoyu Islands to signal the PLAN's uncompromising stance on defending Chinese territory, especially from notoriously invasive countries.
The sub 093B was chased by JMSDF's destroyer and helicopter since the sub entered Senkaku's contiguous zone, presumably, for nearly 24 hours or more.
So, the commander of 093B knew the sub's acoustics data was collected by JMSDF. Even so, the commander of 093B intentionally showed its identity, the sub was type 093B?

The sub willingly entered the contiguous zone, meaning shallow waters. No sub captain wishing to avoid detection enters shallows. There is no thermal layer or only a weak one to dive beneath which is not conducive to hiding. Additionally, Diaoyu Island is disputed territory meaning surveillance around the area is intense and constant. Again, no sub captain wishing to avoid detection would sail next to disputed territory.The sub 093B was chased by JMSDF's destroyer and helicopter since the sub entered Senkaku's contiguous zone, presumably, for nearly 24 hours or more.
The only logical explanation is the 09IIIB captain didn't care that he was to be detected because his mission was to show the flag and possibly gather intel on JMSDF sonar capabilities. He succeeded in the former, because now we all know a PLAN submarine sailed right next to Diaoyu Islands the JMSDF could do nothing but watch. If he was assigned the latter mission, he most likely succeeded in that too since we know the 09IIIB is equipped with a towed extendable sonar array that collects acoustics data given off by JMSDF sonar pings.

He sailed into the contiguous zone adjacent to disputed territory inside a submarine known to be not very quiet..... OF COURSE he knew the sub's acoustic data was being collected, which is why he most likely made a bunch of extra noise to make the acoustic signature inaccurate. Junk intel is worse than no intel and if the JMSDF collected and acts on junk intel, even unimpressive 09IIIs may prove useful in a war.

According to a Japanese newspaper Yomiuri Shimbun, a high ranking official of Japanese Defense Ministry said, "it was fruitful that Japan was able to get Shang-class sub's data".

The "high-ranking official" doesn't even know whether or not the data he got was augmented with intentional clutter. Like I said, there's little chance the 09IIIB's captain didn't foresee getting tracked in waters so it's to be expected that he took precautions to fudge his acoustic signature.

The sub 093B was continuously monitored by JMSDF's destroyers and P-3C at least for 5 days. In your theory, the sub 093B emitted fake acoustic all the time?

If the sub was in the same area for five continuous days, then yes, the captain was well aware of his situation and would've ordered his crew to not enter silent mode. If the sub was actively sailing from elsewhere, then I call bullshit on JMSDF's story. Nuclear subs cruise at 30 knots because they never run out of fuel. 30 knots continuously for 5 days places the sub over 7000km away five days prior to surfacing, which means they were closer to the contiguous US than Japan so there's no possibility the JMSDF would be tracking a random sub in that scenario.

Do you believe 093B was sailing with speed 30 knots for 5 days continuously?
The sub 093B could not run away from JMSDF's destroyer Onami. Onami's max speed may be about 30 knots. Perhaps, 093B's max speed may be slower than 30 knots.
