Antique Japanese Sword Katana Signed by Morimasa with
Tokubetsu Hozon
Certificate
【Description】
This blade was signed by Taira Morimasa (平盛方), who belonged to a prestigious school named Takada(高田). He was active during the Eiroku era (
1558-1570
: Late Muromachi period).
Takada school was founded by Takada Tomoyuki in Takada village, Bungo domain(Ohita prefecture), during the Nanbokucho period. (1334-1338 A.D). Takada Tomoyuki went to Bizen province(today’s Okayama prefecture) to master the sword-forging techniques of BIZEN and returned to the village and trained his apprentices. That is how Takada school started.
Those who forged swords in Takada village before the Edo period were called Taira Takada and Fujiwara Takada during the Edo period. This blade is categorized as a Taira Takada.
During Sengoku Period(the warring state period: from late 15 C to late 16 C), the Takada school forged many swords for many Samurais in Kyushu island. It is said that the reputation of the blades forged by Takada school was close to MINO or BIZEN swords, two of which are the most famous sword forging places.
The Bungo domain was ruled by Otomo Yoshishige(Sorin) during the Sengoku period. Yoshishige and his domain built a strong military and political base there. Yoshishige was known as one of the most famous warlords on Kyushu island. It is said that Takada swordsmiths forged swords for those who served the Otomo clan.
Generally speaking, Kyushu island was prosperous in sword-making because of its long trading history with Asian countries. Many feudal lords on this island fought against each other to gain an advantage in trading. Takada school received many orders as the demand increased among those lords.
The material of Japanese swords(high-quality iron sand and charcoal) was abundant in mount Sobo Katamuki, located near Takada village. We believe Takada school prospered because of its geographic location and natural resources.
It is appraised as a
Tokubetsu Hozon Touken

【 Blade】
Cutting Edge Length (Nagasa)
:
66.2 cm (26.0 inches)
Curvature (Sori)
:
2.12 cm (0.83 inches)
Hamon
:
the crystalline structure which forms along the cutting edge of a blade as a result of the hardening process
Jimon(Jihada)
:
visible steel surface pattern created by folding and hammering during forging process
Nakago
:
Nakago is the tang of the Japanese sword.
Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.
Koshirae
:
Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya (Scabbard), Tsuka (Handle), Tsuba (Handguard).
Fuchi-Kashira
:
A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
While the metal surface has worn down due to aging, it seems the figures of flying birds are engraved on this Fuchi Kashira, especially on the Kashira part. We estimate these birds are wild geese. A wild goose is a migratory bird that represents autumn. Because of its unique call, it is known as “a bird that carries good luck and good news,” meaning that it carries a message with its ancestors and brings good news. This bird was incorporated into designs for sword mountings and family crests. There are various types of family crests with this bird pattern. We would say this bird motif has been familiar to Japanese people since ancient times.
Tsuka and Menuki
:
Tsuka is the handle of the Japanese sword and Menuki is its decoration.
We could see the figures of several birds through the gaps of the Tsukamaki thread. It seems golden paint was initially applied to here and
