NihontoWatchThis is a naginata naoshi wakizashi by the Aoe school, judged to be a work from the late Kamakura period onwards. Although naginata appear in literature from ancient times, extant examples are recognized from approximately the mid-Kamakura period, and some of these were shortened into katana or wakizashi in later generations. Within the Aoe school, examples are occasionally seen from the late Kamakura period onwards, and among zaimei works, Tsuguyoshi and Tsugunao are known. This naginata naoshi wakizashi is thought to have originally been a naginata of an archaic shape with a tip that did not flare much. The jitetsu is itame, partially becoming o-itame, frequently mixed with mokume, generally becoming hadadachi, with jinie, thick chikei entering well, the steel color becoming blackish, utsuri appearing, and partially showing black sumihada. The hamon is chu-suguba style with a slight notare, small ashi entering slightly, the nioiguchi is tight with konie, fine sunagashi appearing, bright and sae, and the boshi is suguba style with notarekomi, returning in komaru with hakikake at the tip, clearly showing the characteristics of the Aoe school. The jitetsu well expresses the characteristics of the Aoe school, and it is a superior work with a nioiguchi that is particularly tight, bright, and sae. On the shinogi-ji of the upper half of the sashi-omote, there are about three locations with fukure-yabure, kitae-ware, etc. In the area of the machi near the habaki-moto, there is small rust where the habaki makes contact.

The Aoe school arose in Bitchu Province, a region celebrated for iron production since antiquity. The early eleventh-century miscellany Shin Sarugaku-ki already lists "the swords of Bitchu" among the noted products of the provinces, and roughly two centuries later the Aoe swordsmiths emerged as heirs to that high reputation, flourishing chiefly in the lower basin of the Takahashi River in such locales as Koji and Manju. The school is traditionally said to have begun with Yasutsugu around the Shoan era, and thereafter it prospered greatly down to the later part of the Nanbokucho period. Within this lineage, works produced up through approximately the mid-Kamakura period are distinguished as Ko-Aoe, while those from the late Kamakura period onward through the Nanbokucho era are broadly termed Aoe. Representative smiths of the Nanbokucho phase include Tsugunao, Tsuguyoshi, Moritsugu, and Naotsugu, yet a great many surviving blades are mumei and attributed to the school collectively rather than to individual hands, reflecting the depth and continuity of the tradition as a whole. The NBTHK identifies two principal modes of Aoe workmanship. The first is a suguha-based temper in which the nioiguchi tends toward tightness, producing a bright and clear effect; the second is the distinctive saka-choji-midare that reached full maturity around the Enbun era (1356-1361), during the height of the Nanbokucho period. Ko-Aoe works are generally ko-nie-deki, with a somewhat shizumi (subdued) nioiguchi in suguha mixed with small undulations; by the late Kamakura period the nie becomes calmer, and in Nanbokucho pieces the nioiguchi tightens and the construction shifts to nioi-deki. It is specifically noted that whereas smiths of other provinces in this period display nie-deki under the influence of the Soshu tradition, Aoe works remain nioi-deki -- a hallmark distinction.
The forging characteristically shows ko-itame mixed with mokume, with finely standing grain producing the so-called chirimen-hada (crepe-like texture); jifu (patchy, mottled surface features) and sumihada (sooty-toned areas) are frequently intermingled. The jihada regularly exhibits midare-utsuri, and toward the cutting edge a layered, streak-like utsuri known as dan-utsuri is a major highlight of the school. Fine ji-nie adheres thickly, with chikei entering well. Overall, when compared with Bizen works of the same era, Aoe blades present a somewhat restrained and austere taste. Across the tradition's long arc from the late Heian period to the close of the Nanbokucho era, the NBTHK consistently praises Aoe works for the brightness and clarity of both ji and ha, frequently employing the term saeru (clear, brilliant) to describe the nioiguchi. Blades are commended for being kenzen (sound and well-preserved), for retaining ample nikuoki (blade "flesh"), and for conveying an atmosphere of sincerity and quiet elegance. The recurring evaluative language -- "the salient points of Aoe are conspicuously displayed," "an especially fine example even among works attributed to this school[[c:1]]" -- underscores the NBTHK's regard for the tradition as one producing consistently high-caliber work whose collective identity is immediately recognizable. The school's Nanbokucho-period output, with its wide mihaba, imposing o-kissaki, and bold boshi that rises and returns with a pointed tendency, conveys the powerful period character of that age, while earlier Ko-Aoe pieces are valued for their thoroughly archaic feeling and deep flavor. Taken together, the Aoe school represents one of the major traditions of western Japan, distinguished by its refined forging, luminous suguha, and the singular visual drama of its utsuri effects.

Bizen in the Nanbokuchō period
Sixty years of war between two courts drove blades long and broad, and Osafune met the demand: Kanemitsu and Chōgi led forges serving the provincial warriors who did the fighting, while Sōshū influence arrived with the armies to create Sōden-Bizen.
A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
The NBTHK (Nihon Bijutsu Tōken Hozon Kyōkai, the Society for the Preservation of Japanese Art Swords) is a public-interest incorporated foundation founded in 1948 and supervised by Japan’s Agency for Cultural Affairs (Bunkachō); it is based at the Japanese Sword Museum in Tokyo. Its expert panels physically examine each submitted work (shinsa) and issue a certificate (kanteishō) ranking it by artistic and historical merit. NBTHK papers are the most widely recognized standard of authentication for Japanese swords and fittings.
