A Local Perspective on Life in Tsukuba, Ibaraki, Japan.

Tsukuba Statistics

Tsukuba City Hall has published a 144-page document with various statistics related to the city. The document is only available in Japanese, but it is a treasure trove of information about the city.

For example, there is a diagram on page 15 (of the pdf file, page 5 of the paper document) that outlines the history of merges that created the city. I knew that Tsukuba was created out of Toyosato Town, Oho Town, Sakura Village, Yatabe Town, Tsukuba Town, and Kukizaki Town, but I did not know that Toyosato was originally Kamigo Town, which itself was originally Kamigo Village.
