Interestingly, wiki links back to a Paul Graham article referencing Ooka http://www.paulgraham.com/property.html

From that article:

> In 1956, an illustrated book was created by I.G. Edmonds, an American military officer. Published by the Pacific Stars & Stripes, it was called Solomon in Kimono: Tales of Ooka, a Wise Judge of Old Yedo.[4] Edmonds' work was published in 1961 as Ooka the Wise, and then in 1966 renamed The Case of the Marble Monster and Other Stories and made widely available to American schoolchildren by the Scholastic publishing company.

Perhaps GP read the story thanks to Edmonds.

That’s Ooka for sure. I did a PowerPoint on it for my criminal law class.
