Just left Hiroshima and apart from the obvious visiting place also managed to go out to an island that was a Kaiten training base. Museum guide had very little English but was very helpful. It was supposedly no photography but as my partner assisted via Google Translate I was able to get a few photos.

They had a Kaiten interior that was built a bit overscale for a movie and a full one outside and there was also a more rusty one at the port we caught a boat out to the island from.

Below is the tunnel used to transport Kaiten out to the training facility including some docking areas and two pens that they would have sailed from.  The first run was 2kms out and back building up to circumnavigating the island.

Typical bullet train looking more like a fighter cockpit.

The Yellow Submarine and Volks stores were located conveniently close to each other with the Volks on the 4th floor of a mall next to a railway shop. The Volks shop whilst smaller than the Kyoto one had a similar layout and feel with less actual aircraft tanks etc in comparison. And yes I finally succumbed and bought a lot of modelling accessories as they were around 50% of the usual Aussie price. It made me a bit more experimental in my choices including a cheap scriber bit.
And these were just weird as things to buy.
