Antique Japanese Sword Katana Attributed to Kasama Shigetsugu with NBTHK Kicho Certificate
【Description】
This blade is attributed to Kasama Shigetsugu (笠間繁継). Shigetsugu was born in Shizuoka Prefecture in the 18th year of the Meiji era (1885). He was an apprentice of Morioka Masayoshi, his uncle. He also worked under the name Kasama Ikkansai Shigetsugu (笠間一貫斎繁継) while his birthname was Kasama Yoshikazu (笠間義一).
In 1903, when he was late teens, he moved to Tokyo. Later on, he become one of the masters of Nihonto Denshusho. Nihonto Denshusho is a Japanese Sword Training Institute dedicated to preserving and teaching the traditional techniques of Japanese sword-making (nihonto). Established in 1926 by renowned swordsmiths such as Kurihara Akihide (栗原昭秀) and others, the institute was created in response to declining interest in traditional sword-making during the Taisho and early Showa eras. Its goal was to train a new generation of craftsmen in the ancient art of forging, polishing, and appraising Japanese swords. After teaching his sword-forging techniques there, he became the head master of another institution called Tozan Teinai Tokiwa Matsu Token Kenkyujo, which served for the same purpose of Nihonto Denshusho.
He was a Kunaisho Toko (宮内省刀工), which means that he served the Ministry of the Imperial Household as a swordsmith. He also received multiple awards during his career. It is said that he dedicated his career to preserving the tradition of Japanese sword making.
Given that he was the teacher of Shohei Miyaeri (宮入昭平), who was a Living National Treasure in Japan, and that he was appointed to the position of Sword Specialist at the Imperial Household Agency, it can be inferred that his remarkable craftsmanship was highly appreciated.

【Blade】
Cutting Edge Length(Nagasa)：68.4 cm (26.9 inches)
Curvature(Sori)：1.6 cm (0.62 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
Kissaki：Kissaki is the tip of the Japanese sword.
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.
Tsuka and Menuki：Tsuka is the handle of the Japanese sword and Menuki is its decoration.
The motif of this Menuki is the combination of bats (蝙蝠, Koumori) and the moon (月: Tsuki). According to a theory, the continent largely influenced the introduction of bats as a pattern. This animal is a symbol of happiness and longevity. In the continent, it was popular as an auspicious pattern that brings good luck because its Japanese name letter “蝠” and another word “福 (happiness)” have the same sound. The design depicting five bats is called the Gofuku (五福) and symbolizes longevity, wealth, health, descendants, and prosperity.
The sun and the moon have been treated as objects of worship since ancient times. Some people considered them the symbol of authority. The moon pattern has various shapes depending on the waxing and waning of the moon: full moon, half-moon, crescent, or hazy moon. There is also the idea: as the moon changes its shape depending on its fullness, it represents growth and development. Moreover, the moon is a classic design that symbolizes autumn: the combination of a moon with rabbits, deer, autumn grass, waves, etcetera.
Tsuba and Habaki：Tsuba is the handguard for the Japanese Sword and Habaki is the equipment to make the blade not touch its scabbard inside. It prevents the blade from getting rusty and chipped.
The motif of this Tsuba is a turnip (蕪, Kabu). Kabu is one of the seven herbs of spring in Japan. People eat these herbs on January 7th, hoping for good health, and it is believed that it would protect people from evil spirits. And it is also said that the word “Kabu (蕪)” was said to be associated with the word “Kabu (頭, head)”, another pronunciation of Kashira (頭). Therefore, a turnip has been cherished as a food of good luck among Samurai families, who hoped to become the head or leader.
Saya： Saya is the scabbard for the Japanese sword.
This Saya is decorated with traditional Japanese craft method, the Raden (螺鈿: Raden). The Raden is a decorative technique that is often used for traditional craftwork. It uses the pearl part of seashells and puts it into the engraved surface of lacquer or wood. Thanks to its iridescent luster, it gives a luxurious look to works.
