Daimyo Flags, 19th Century

Ottfried Neubecker, in Le grand livre de l'heraldique (French edition of Heraldry: sources, symbols and meaning), mentions as a source for Daimyo flags: H.G. Stroehl Japanisches Wappenbuch : Nihon Moncho', Wien (1906) [stl06]>and shows on p. 210-211 some standards used by the Damyos of the coast in the 19th century.

Tokugawa Dynasty Flag

image by António Martins-Tuválkin, as adapted by Peter Hans van den Muijzenberg, 16 September 2008

Before August 1853 white black white triband was used ensign representing Tokugawa Shogunete after then Hinomaru was used.
The original family crest of the Tokugawa is Nakaguro = one black horizontal band in white disc not blue. Japanese family crests are always black and white.

So with new discovery of the document I have to correct my comment on Tokugawa Dynasty flag. The report of the ensign with horizontal black band is wrong.

Erroneous Tokugawa Dynasty Flag

This flag is from several old plates. It appears to be an erroneous flag flag or the flag of Tokugawa, the Japanese shogun dynasty, c. 1850.

I have investigated this flag from lots of flag-related books/records available in Japan but cannot find out description of such flag.
The flag is erroneous and has been reported mistakenly to Europe/America in 1850's . But the fact was found that in 1854 the Tokugawa shogunate adopted Hinomaru as civil ensign and white, "black", white horizontal flag as Shogunate vessel's ensign together with streamer of white/blue/white/blue/white/blue stripes hoisted. The white and black colours were used by the Tokugawa family.
I suppose Europeans (Dutch, I believe) reported this Shogunate vessel's ensign with wrong colours.
More interestingly until 1854 there was a reversed proposal in Shogunate that Hinomaru be Tokugawa Shogunate vessel's ensign and white. black, white stripes be civil ensign.
Incidentally the Meiji government restored/modified this idea in Japanese civil ensign (white, black, white horizontal stripes with hinomaru in the center) for a short period between 1870-1875.

The blue is wrong. The Tokugawa used black. Please refer to my comment above.
