It's a kind of heritage that should be in the museum !
This is not the ruin but was like that before a cafe was opened in this old theater building. The name is "Kanashibetsu Roman-za" which remains in minds of many people who had lived around this area and adjacent cities and towns many years ago.
The entrance area is used as a cafe and the stage and the area between the stage and the entrance are used as a open-air theater. The roof of original auditorium collapsed and the original building was divided into two parts.
Originally, the chimney hole was used for a certain instrument.
According to the custodian who runs the cafe in this building, the resource of the light for the projector was the fire obtained from burning copper wire(stick) in this drum.
Only a few machines are left in Japan and two of them are in the old theater. The others are in the museum in Tokyo.
Can you see the chimney on the top ?
That is exhaust pipe and connected to the chimney outside.
This machine is to increase the voltage of electricity from 100 to 300 volt. It has surprising item in it. This kind of gadget can be seen only in this old theater.
It works even now with the size of 40 cm high.
Have you ever seen such huge vacuum before ? It was the first time for me. I am very proud of the craftsmanship of Japan !
