Nanako is a metal engraving technique that was brought to
Japan from Sassanid Persia via China in the Nara period.
A chisel with a small cylindrical tip is used, and millet-sized
fine grains are densely driven into the metal surface
to form a base called Nanako, a basic surface decoration.
Shakudo (赤銅) is an alloy of 96-90% copper, 4-10% gold.
Currently, copper sulfate, artificial green patina are
dissolved in water to create a chemical solution for
the treatment of the alloy. When an alloy is boiled in this
liquid, a film of cuprous oxide is formed on the surface.
5-10 nano-sized gold particles are dispersed in the alloy,
which reduces the reflection of light from the alloy surface,
resulting in a jet-black color of a wet crow's feather.
Fuchi : Mouse and a folding fan
Fuchi is a metal fitting attached to the base of
the hilt of a Japanese sword to fix the blade.
Dimensions: 3.6 cm x 2.1cm x 1.4cm, Wt. 26.3 g
Production period: Edo (1600-1868)
Medium: Copper-gold alloy (shakudo), silver and gold
As you see, a mouse is engraved and a folding fan
is left next to it. From a distance,
the meaning of the design is hard to understand.
On a silver fan, you can find tiny Daikoku-ten,
one of the legendary Seven Lucky Gods in Japan.
He is holding a magic mallet, and in the legend,
he can tap out anything wished for with this hammer.
The mouse was thought to be the messenger of Daikoku.
The design of this metal fitting for the Japanese sword
was a deep wish and prayer for the owner's good luck.
Kashira : turbulent waves
Kashira is the metal fitting which is attached to
the top of the hilt of a Japanese sword.
Dimensions: 3.7 cm x 1.7cm x 0.8cm, Wt. 9.8 g
Medium: Copper-gold alloy (shakudo) and gold inlay
The design of this fitting is called Tatsunami and very popular.
In Japan, this means turbulent waves and seawater splashes.
The wave pattern is applied to the entire surface of the
jet-black Shakudo, realizing powerful movements in the design.
In 1860, the Shogunate dispatched a mission to the United States
to ratify the Treaty of Amity and Commerce between two countries.
Tadanori Oguri boarded The USS Powhatan, the U.S. Home Fleet
as a member and the inspector appointed by the Shogunate.
Tadanobu Oguri's family belongs to Hatamoto, high ranking samurai
of Tokugawa, who had the right to an audience with the shōgun.
And his family crest is Maru-tatsunami: turbulent waves.
