Antique Japanese Sword Katana Signed by Kunimasa with NBTHK

Certificate
【Description】
This blade was signed by Hojoji Tajima no Kami Tachibana Kunimasa (法城寺但馬守橘国正). Hojoji is the name of the prestigious school he was part of, and Tajima no Kami is an honorable official title for his excellent craftsmanship. Tachibana is his last name.
He was active during the early Edo period (1673-1688) and one of the most prominent figures in the school in Edo city (Today’s Tokyo). Since Kunimasa was a highly regarded swordsmith, this blade might have been made for a high-class Samurai who resided in Edo. Based on the back of the signature, this blade was created when he was 48 years old when he mastered a high level of craftsmanship.
Hojoji school was founded by Hojyoji Kunimitsu, a renowned swordsmith in Tajima no Kuni (Today’s Hyogo prefecture) during the late Nanbokucho-Muromachi period. It is said that Kunimitsu was one of three apprentices of Sadamune, who was one of the most prominent makers in Soshu province (Today’s Kanagawa prefecture).
Hojyoji Masahiro (法城寺正弘), an offspring of Kunimitsu, is the one who moved to Edo city and established the Edo Hojyoji school during the early Edo period. He brought his apprentices, including Kunimasa from Tajima no Kuni, based on available records. And those who came to Edo city with Masahiro received the last name of Tachibana.
The blades forged by members of Edo Hojyoji swordsmiths closely resemble Kotetsu, one of the most famous swordsmiths. Other renowned swordsmiths who belonged to this school are Kaneshige, Sadakuni, and Yoshitsugu. The school was prosperous during the Edo period and forged many blades for the Edo government. The founder, Masahiro, once resided in Mito domain (today’s Ibaraki prefecture) to forge swords for Tokugawa Mitsukuni.

Fuchi-Kashira
:
A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
The theme of this Fuchi-Kashira is the Unryu Zu (雲龍図). It is a combination of dragons (龍) and clouds (雲). Regarding the cloud pattern, clouds bring rain and snow, and their movements significantly affect the weather of the day. Due to its supernatural power, a theory says that gods, spirits, and dragons dwell in the clouds. As mentioned in the dragon design above, there is a religion that worships the dragon as a water god in Japan. It might be one of the reasons why the combination of dragon and clouds motifs is often seen even in sword mountings.
Also, clouds bring blessed rain and snow, and their movements significantly affect the day’s weather. Due to its supernatural power, a theory says that gods, spirits, and dragons dwell in the clouds. In Japan, there is a belief that w
