Description

It has arrived, it has arrived—a masterpiece by Yamashiro Kyo Rai Kuniyasu has arrived. This sword was originally a magnificent *o-tachi* of approximately 2 *shaku* 8 *sun*, which was *suriage* in later generations; because it became *mumei*, it was given the *kiwame* of Rai Kuniyasu. Rai Kuniyasu was the son of the ultra-famous swordsmith Yamashiro Rai Kunitoshi, or perhaps the son-in-law of Rai Kunitoshi. Because a work exists with a date of Gentoku 2nd year (1330) (693 years ago) of the late Kamakura period, his production era can be confirmed. Among the *zaimei* *tachi* of Rai Kuniyasu, the 3 *shaku* 5 *sun* *o-tachi* located at Yusuhara Hachimangu in Oita Prefecture is famous. He is a master smith of the era spanning the Kamakura period to the Nanbokucho period, contemporary with Soshu Sadamune, Yamashiro Rai Kunitsugu, and Bizen Osafune O-Kanemitsu. He later moved from Yamashiro Kyo to Nakajimasho, Awaji in Settsu. As you can see, this sword exhibits a magnificent *sugata* with a wide *motohaba*, wide *sakihaba*, and an extended *kissaki*. The *jigane* is a well-packed *itame-hada* with abundant *ji-nie*, forging a superb steel. The *hamon* is a *suguha* style with *ko-nie*, containing *choji* and *ko-ashi*, firing a wonderfully spirited blade. A magnificent Rai *tachi* such as this is a masterpiece with a very exciting future for *shusse*. As this is the first time it has appeared "raw" in the world, we are offering it at a special bargain price. Please enjoy this masterpiece by Rai Kuniyasu.

About the school

Nakajima Rai School中島来派

43 Jūyō Tōken

The Nakajima Rai designation identifies swordmaking traditions established when Rai Kuninaga, a disciple of the Kyōto master Rai Kunitoshi, relocated to the Nakajima district of Settsu Province during the late Kamakura period. This move represented both geographical expansion of Rai school influence beyond the imperial capital and the deliberate transplantation of technically sophisticated Kyōto *nie*-based forging practices into a provincial setting. According to historical sword compendia, smiths using this designation are traditionally counted as two generations: the first active during the Gentoku era (1329–1331), and the second working through the middle decades of the fourteenth century, spanning the Shōhei and Ōan eras. Signed examples are exceedingly rare, and most attributions rest on stylistic analysis of unsigned blades greatly shortened from their original dimensions. Nakajima Rai workmanship faithfully perpetuates the core technical vocabulary of the main Rai school while exhibiting slightly more restrained execution. The forging typically shows compact *ko-itame-hada* or *itame* mixed with *mokume* and *nagare-hada*, frequently with a tendency toward standing grain; the surface is heavily laden with fine *ji-nie* that forms in thick, crystalline masses, producing a bright, clear appearance. *Chikei* enter actively and repeatedly, and faint *nie-utsuri* often appears along the *shinogi* side. The *hamon* follows a characteristic broad *suguha*-based pattern, into which are mixed *ko-gunome*, *ko-chōji*, and small *midare* elements; within this foundation, *ashi* and *yō* enter abundantly, and the *nioiguchi* is uniformly described as bright and clear. Internal activities—*kinsuji*, *sunagashi*, *yubashiri*, *hotsure*, *kuichigai-ba*, *nijūba*, and *uchi-noke*—appear frequently along the *habuchi*, creating rich variation within the temper line. The *bōshi* typically forms *ko-maru* with *hakikake*, often showing vigorous activity. The overall impression is one of technically accomplished *nie-deki* work in which the foundational *suguha* serves as a vehicle for highly active crystalline formations and internal dynamics, closely resembling the style of Rai Kunimitsu but yielding slightly in artistic rank. Extant Nakajima Rai blades almost invariably preserve the bold proportions characteristic of Nanbokuchō-period production: wide *mihaba* with little taper from base to tip, shallow or deep *sori* (often retaining *koshizori* or *wazori* despite shortening), and extended *chū-kissaki* or *ō-kissaki*. Even when greatly shortened, these blades retain an imposing, martial presence that pairs well with the vigorous, *nie*-laden forging and temper. The technical consistency across designated examples—tight *itame* with thick *ji-nie*, broad *suguha* with active *nie*, and bright *nioiguchi*—establishes a coherent stylistic profile that clearly descends from Kyōto Rai traditions while expressing a distinctive provincial character. The combination of robust construction, excellent preservation in surviving examples, and flavorful *hataraki* within both *ji* and *ha* renders Nakajima Rai an important regional expression of late Kamakura and Nanbokuchō swordmaking, preserving the technical sophistication of the capital school in a relocated context.
