Far before World War II Japan had already begun integrating western-style architectural designs into its buildings. This old factory is an interesting example. The wooden building on the left is somewhat western-inspired, but has a traditional Japanese tiled roof. The dark wood siding with a white border on top is a common architectural motif I've only seen in Japan.
The brick building on the right looks like it could have come directly from my hometown in America, but if you look closely you can the roof, especially the top, is very traditional Japanese.
