The blade is just samazing and its curvature is extraordinary

Inshu Zumi Fujiwara Kanesaki(因州住藤原兼先) forged swords in the early Edo period. He first started his career in Mino province(Gifu prefecture), mastering MINO-DEN (one of the most famous Japanese sword styles). He is ranked in top-tier MINO-DEN swordsmiths in the early to mid-Edo period.

He moved from Mino province to Tottori province and served the Ikeda clan, who ruled the Tottori prefecture (Tottori domain) for about 240 years. Ikeda clan was one of the most powerful feudal lines in that region.It was a privilege to work for the feudal family, and only highly skilled swordsmiths were entitled to this honor.

Tottori prefecture is located in western Japan . He forged swords near Tottori castle. The swordsmith name’s Kanesaki (the total of 11th generations) lasted at the end of the Edo period when feudal society turned to modern society, and the Samurai government lost their authority.

MINO-DEN had its origin from YAMATO-DEN in the late KAMAKURA period(1280-1330). It flourished in the MUROMACHI period(1333-1573) and continued until the EDO period(1603-1868).

MINO-DEN especially prospered during Sengoku Jidai (Warring State period) due to the high demand for weapons. And the location of Mino province beat others. Akechi Mitsuhide controlled Mino province, and Nobunaga Oda ruled Owari province, and Tokugawa Ieyasu was the lord of Suruga (Neighboring areas).

There was high demand from those powerful feudal lords and their retainers. Furthermore, so many wars occurred between the Kanto region and the Kyoto area.

Mino is located in the middle, making feudal lords feel convenient to order swords from MINO-DEN. The blades forged in MINO provinces also had the reputation of its practical design and sharpness. Many feudal lords demanded swords forged in the Mino province. The tradition of excellent sword forging skills had been passed to the Edo period, and Kanesaki is a good example.

The four-diamond mon (family crest) of the Kamei clan is historically classified under the Meyui (目結) category of Japanese heraldry, specifically known as Yotsumeyui (四つ目結 - "four eyes") or Sumitate Yotsume (隅立て四つ目) The Kamei clan, led by Kamei Korenori, became Daimyo of the Tsuwano Domain until the Meiji Restoration, using these types of geometric emblems to signify their family lineage.

Geometric designs like the Yotsumeyui were highly favored by samurai clans during the Sengoku and Edo periods because their bold, minimalist structures made them instantly recognizable on banners, armor, and helmets across chaotic battlefields.

Historical records detail the military life of Kamei Korenori (1557–1612), tracking his transition from a desperate resistance fighter trying to revive his fallen master's clan into a strategically flexible daimyō who served all three great unifiers of Japan: Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu.

Following the collapse of the Amago cause, Korenori transferred his allegiance directly to Toyotomi Hideyoshi For his combat distinction in subduing the San'in region, Hideyoshi granted Korenori Shikano Castle in Inaba Province

Korenori played an aggressive role in the subjugation of Tottori Castle. Records indicate that he joined Saimura Masahiro in a scorched-earth campaign, burning down the outer civilian settlements surrounding Tottori Castle to completely isolate the Mōri garrison, forcing its commander to commit seppuku to spare his starving men

Upon Hideyoshi's death, Korenori recognized the shifting political tides and sided with Tokugawa Ieyasu's Eastern Army during the pivotal Battle of Sekigahara.Korenori pleaded with Hideyoshi for coastal lands in Izumo. When diplomatic truces forced Hideyoshi to leave Izumo in Mōri hands, Korenori audaciously asked for the Ryukyu Islands (modern-day Okinawa) instead. Hideyoshi famously painted "Kamei, Lord of Ryukyu" onto a folding paper war fan as a symbolic grant. In 1590, Korenori assembled a fleet of 3,500 men at Nagoya Castle to invade the islands, but his fleet was physically blocked by the Shimazu clan of Satsuma, who claimed exclusive domain over the kingdom.

Korenori put his naval infrastructure to use during Hideyoshi's continental campaigns, commanding ships and troops under the Toyotomi banner. In a striking historical crossover, Korean records note that after a naval engagement, local warriors discovered Hideyoshi's signed "Lord of Ryukyu" war fan among the wreckage of a captured Japanese vessel
As a direct reward for his calculated realignment during the Sekigahara campaign, Tokugawa Ieyasu expanded Korenori's fiefdom from a minor 13,000 koku holding to a robust 43,000 koku domain. This established the financial power that secured his family's rule over the Tsuwano Domain for the next two and a half centuries.
