Episode 306 – The Prisoners of Nanbu, Part 1

This week, we’re taking a look at the foreign policy of Edo Japan by starting a deep dive into a complex case study: the tale of the 10 prisoners of Nanbu domain!


Hesselink, Reiner. Prisoners from Nambu: Reality and Make-Believe in 17th-Century Japanese Diplomacy.

Matsukata, Fuyuko. The Dutch and English East India Companies: Diplomacy, Trade, adn Violence in Early Modern Asia. 


Anthony van Diemen, the man behind the voyage of the Castricom and Breskens to Japan.
Abel Tasman’s voyage of 1642-43 is in red. His voyage was planned by van Diemen at the same time as the Breskens/Castricom one.
A map of northern Honshu showing Morioka/Nanbu domain in mustard yellow. The red is Hachinohe domain; at the time of our story, it would have been a part of Nanbu, as it was broken off into a separate domain later during a succession dispute.
Nanbu Shigenao, 28th family head of the Nanbu and lord of Morioka domain.
A partial view of Yamada bay.
A map of the voyage of the Castricom, assembled about half a century after the fact. This map shows something that I got wrong; I had speculated that the island the Castricom discovered was Sakhalin, but this makes it clear that the island was Kunashir (which Vries named Staten Island, though that name didn’t take surprisingly). For reference, the Japanese mainland appears on the bottom of this map.
An Italian map later put together from notes taken from the Castricom. Voyages like these were essential to European mapmakers expanding their understanding of the world’s geography. Note that Tartary is still on this map (more or less on the Russian Pacific Coast.)
