TIL Fukuzawa Yukichi railed against patent medicines in his day.

Despite protestations to the contrary, deep dish is good! Especially if you want to nap afterwards. Whether or not its pizza can be left to a future discussion. Personal favorite is Giordano's.

Yep! The shogunate only did full surveys twice in its existence, with the second being in 1868. So relying on these only gets you brief snapshots of a pretty fluid system.

The team at Harvard that assembled the original files did a great job, and I'm glad to be able to put it together for broader use.

That data is now under a CC0 license and in turn, I've put together a domain map based on that data, also under CC0. Hopefully this will be useful to someone!

The GIS data for this map comes from Harvard's China Historical Geographic Information System (CHGIS). The data was originally CC BY-NC-SA but is now CC0 from its upload to Harvard Dataverse.

So, I wanted a domain map, but I couldn't find one. Fabian Drixler has shown far more accurate maps, but are not under an open license, to my knowledge. However, Harvard CHGIS hosts GIS data based on a map from the Nihonshi Nempyo Chizu, in turn based on the 1664 shogunal survey.

their relation to the Tokugawa: the Shinpan domains of the Tokugawa cadet branches, the Fudai domains of direct Tokugawa retainers, and the Tozama domains of the non-direct Tokugawa retainers.

They varied in size from the tiny to the span of multiple provinces. And they all mixed together.

These domains were distinct from the older kuni or "provinces," although they still officially existed during the period. It's also kind of hard to find a map to use.

The map is important! It's sort of hard to visualize just how *messy* domains were. They were divided into three types based on

And if you are a history account and have a cool history deep dive thread, @ me on it, both because I love that stuff and also because I love retweeting (or whatever we do in place of that word) that stuff.

Jansen's "The Making of Modern Japan," though it has a lot of discussion around the Restoration/Boshin War, gives the actual events of the war very little space (mostly the fall of Aizu and its treatment after the war). It feels like a common trend.
