i cannot belive how many there are on that map, but apart from that i can also tell you that a japanese channel made a up-close video of the siren on the iga city hall, and its here : https://www.youtube.com/watch?v=csTZcYn_DPQ (and at 4:42 the siren activates)

Ports
I know that the actual number of ports on each rotor is pretty unknow so, I decided to calculate the ports for the Tokiwa siren and here are my results..
F3-6 port
G3-7port
A4-8 port (Very sharp)
B♭4- ?8 port through gear reducer
C4-9 port
D4-10 port
E4-?12 port
F4-12 port
G4-14 port
A5-16 port
6 port came from an image of the siren
The rest came from a generator by nconvert and Ryan. Find it HERE

All these videos have been found before and are in Evan's playlist
The map was made by IHaveAName and can be found on page 11.

Quick bump:
The Iga City Hall music siren is now protected as a "Tangible Cultural Property." Unfortunately, this article is behind a paywall so I can't read it. I guess this means it's a historic site like the NRHP here in the United States.
