I went to this museum twice before the covid outbreak. Since then I always wondered how did they get the Zero inside, fully assembled, wings removed, maybe the glass doors in front of the Zero are moveable or maybe they lifted it with a crane? Same questions go to this train, the artillery guns, the kaiten, the tank, the Suisei, Yamato shells etc. I don't exactly remember how the floors of the museum look like, it always intrigued me. I also went to the Yamato museum in Kure, the 1/10 scale replica of the Yamato is really impressive. They also have an A6M7. I hope to go there again some day.
