Here's something for creative discussion, (From the book I've been banging on about - The Truth of the Ancient Ways by Anatoliy Anshin).
I chapter 3, Anshin states that the Bakufu Military Institute set up three Gunnery Schools in Edo in the years 1843, 1844 & 1852.
In 1857, the Bakufu Senior Councilor Abe Masahiro died, his political rival Ii Naosuke takes over the position and promptly declares that old values should be instituted and Military Archery which was almost extinct should become the main form of training and in some areas the instruction in Gunnery was abolished.
In February 1860, the Bakufu Military Institute moves to new premesis in the Ogawa Cho area of Edo and under Ii Naosuke's expressed order, Archery is the main military art taught..........
In March of 1860 Ii Naosuke is assassinated by 17 Mito Samurai in what became known as the Sakuradamon Incident
Jo, I also know of this parcel of land with wonderful sea views, which happens to be for sale, it's above water for most of the year and would make a great investment opportunity...... I'd invest in it myself but I am helping out a poor unfortunate gentleman from Lagos who has fallen upon hard times and has a sizeable fortune in a London Bank which he cannot gain access to.....
Seriously guys, I'm fascinated by the possibility that the prime movers and shakers of the Bakumatsu were making such "Last Samurai" - like decisions in the face of the oncoming tide.
I'm going to see if I can find more information about this edict, perhaps at the National Diet Library or maybe if someone has a copy of William Beasley’s Selected Documents on Japanese Foreign Policy, 1853-1868 (Oxford University Press, 1955) they can scan through it for a mention of the edict?
