Chapter 120: Survey of Daimyo in the Era of Nobuhiro
After the torch was passed to Oda Nobuhiro at last in 1665, the fate and affairs of Japan saw ups and downs defined by war, trade, factionalism, and recovery. While Azuchi certainly felt all of these variables firsthand and determined the topline of the realm to a large extent, the feudal nature meant that daimyo lords and overseas governors wielded local control and collectively influenced the state of Japan through their own individual successes, failures, and dynamics.
The death of Sakuma Moritora after 1672 left a hole not only in the ranks of the Japanese military apparatus but also amongst the daimyo of the Kanto and Oshu regions. In his own domain, he was succeeded by his son Moritsuna (佐久間盛綱) who had very little military experience but proved to be a competent steward of his father’s domestic legacy, continuing to grow Sakata as a growing city and a primary outpost for the northern fur trade. However, he died only 7 years later at the age of 33, leaving his 7 year old son Morichiyo (盛千代) [1] at the head of the clan and his senior retainers to govern the domain on behalf of the new child lord. Outside the borders of the Sakuma domain in southern Dewa province, Nanbu Shigenobu established himself as the most senior and influential lord in the Oshu region, although no one could truly fill the shoes the Tiger of the North left empty. Nevertheless, Shigenobu’s prestige as a secondary leader of the Hokushin-ha and his brother’s high position in the Japanese navy was more than enough for him to attain Moritora’s old position of Chinjufu-shogun. As the new chinjufu shogun, the Nanbu lord provided the shogunal cavalry with horses from his domain, which were reputed to be some of the fastest in the entire realm. As a daimyo lord, Shigenobu pursued a high-export economic strategy for his domain due to the frequency of local famines exacerbated by the frigid climate in the region. Although this initially involved supporting merchants in making Hachinohe (八戸) a key port in the fur trade and fishermen in expanding their catches and exports, a ji-shoukai centered around shipbuilding and timber would be established after the naval reforms of Tagawa Seikou with the support of Shigenobu’s younger brother and naval commander Naofusa.

Just north was Ezo where the Kakizaki clan contended and interacted with the indigenous Ainu tribes while also gradually growing . For most of the 17th century, the main line was plagued by relatively weak heads, including Takahiro and Norihiro, due to their short lifespans. As a result, the cadet branches of the clan that had begun ruling autonomous fiefs under the arrangements Kakizaki Kinhiro had set in the 1630s had relative free reign. They ran their domestic affairs and relationships with the Ainu, working together when necessary for the clan at large but also often squabbling with one another. The autonomous fiefs also strived to attract settlers from Honshu either interested in starting a new life or profiting from the fur trade. However, the decentralized nature of the Kakizaki clan, the harsh climate, and the strength of the remaining independent Ainu hindered growth, with only the western part of the island truly witnessing de facto Japanese control despite Azuchi’s claims over the entire island. This would be further complicated by the formation of a united Menashir Ainu polity in the late 17th century by the chieftain Shakushain [2] that sought to contain Japanese expansion through deterrence and diplomacy while also maintaining friendly trade relations with fur traders, even those affiliated with Oshu daimyo. In short, Ezo remained a contentious landscape lacking unity for one power to achieve dominance
The Kanto plain, meanwhile, thrived, its landscape largely spared the devastation of the Manji War and its daimyo only narrowly escaping deployments to the mainland against the Lesser Jin and Joseon. The vast flat landscape was perfect for agriculture and over time the entire region would become one of the chief breadbaskets of the realm, Kanto agricultural products being transported overland and by sea across the home islands and even beyond. The agricultural boom of the region led to a population boom as well, dotting the Kanto plain with prosperous farming towns and coastal ports. No part of the Kanto plain symbolized this more than the province of Hitachi, ruled by the prominent Satake clan and the smaller Minagawa clan and agriculturally the most productive province in all of Japan. In addition to rice, buckwheat, lotus roots, and soybeans were chief crops grown in the province The larger of the two domains in Hitachi province, ruled by Satake Yoshizumi (佐竹義処) in 1682, had risen in power and prominence ever since the Oda Kamakura-fu was dismantled and the Hojo clan lost its regional preeminence in the aftermath of the Furuwatari War. As a result, the domain capital of Mito (水戸) grew into a regional urban center of its own.

Further in the center was Musashi province, home to the Musashino clan, formerly the Oda cadet branch that ruled the entirety of the plain as Kamakura tandai. Similar to Hitachi province, Musashi province had flowered into an agricultural heartland, being at the heart of the Kanto plain and sharing a coast with the Uchiumi (内海) [3]. The already fertile landscape was further expanded through a series of drainage projects directed by Toshinao and Toshikatsu aimed at converting marshland into farmland. The domain capital, Musashino, was the second largest city on the Kanto plain, only behind Kamakura, and was also at the crossroads of several major land routes. Beyond Musashino, the clan also attempted to build up Edo (江戸) as a major port, although their efforts proved mostly unsuccessful and Shimoda and Kamakura continued to be the major ports of the Kanto region. Part of what was instrumental behind the prosperity and stability of Musashi province was the clan’s successful fusion of hereditary retainers with ex-Hojo ones who were left behind when others moved to Izu province or became minor lords in Shimousa province. The successful integration of those who once fought each other helped forge a new future for the centerpiece of the Kanto plain.
The main Oda lands of Owari, Mino, Yamashiro, southern Oumi, and Izumi provinces also underwent major changes in governance throughout the 17th century. Out of them, Mino, Owari, and southern Oumi were traditionally ruled by the Oda heir from Gifu, with Yamashiro and Izumi provinces being governed by a mix of magistrates and nobles owing to them being host to Kyoto and Sakai respectively. However, when Nobutsugu died in 1653 and left the clan to the 5 year old Nobuhiro, the subsequent regencies appointed governors to take over the responsibility the heir usually took up. This change would be permanent, for even after the birth of Nobuie this arrangement continued and the heir now lived in Azuchi alongside his father, the daijo-daijin. Although the new status quo was yet another factor behind the stagnation of Gifu with the absence of the heir, it also enabled the political and economic re-emergence of Kiyosu, the minor lords of Owari visiting and patronizing the latter city as an administrative and commercial center more than before. These changes also did not alter the bureaucratic pipeline that had allowed samurai from the core Oda lands to make up a disproportionate portion of the Azuchi bureaucracy.
Finally, in the latter half of the 17th century, a new generation of Christian daimyo emerged, making their presence felt in a fashion not seen since the suppression of Catholicism during the Iberian-Japanese War. These Christian lords, however, were part of the ever-flourishing Yamato Church and also stuck to Azuchi’s principles of religious tolerance, preventing the suppression of Shinto-Buddhism. Nevertheless, the religious identification of the lord did increase the presence of the faith in the most prominent of these Christian lords, Ukita Nobumasa of Bizen and Mimasaka provinces. Nobumasa had converted to Christianity in 1667, becoming the first member of the Ukita clan to do so. Under the rule of his grandfather, the famous Nobuie, the Yamato Church had already established a firm presence in the Ukita domain, owning tracts of vineyard for wine production, and the conversion of Nobumasa only added on. In addition to cultivating and patronizing Yamato Christianity, Nobumasa continued to bolster his domain a proto-industrial powerhouse, operating ji-shoukai centered around Bizen ware (備前焼) production and tatara steel smelting (たたら製鉄).

In contrast to the recent interactions between the Ukita clan and the Yamato church, the Otomo clan had maintained a relationship with Christianity for over 100 years, the entire clan being part of the Yamato Church by this point. Nevertheless, the 17th century had been a bumpy century for the Otomo clan, as the main line of the clan had died out with the death of Yoshinori (大友義乗) in 1612 and the fate of the clan lay with his heirless uncle Tahara Chikamori. It was during this time that northern Kyushu dealt with the transition from Catholicism to Yamato Christianity, the Otomo clan itself forced to convert to the new non-Roman church and eradicate dissident Kirishitans amongst the populace. After this rather gloomy era accompanied by some level of destruction, Chikamori died in 1643, succeeded by a distant descendant of Otomo Yoshimune to attain the adult name Yoshitaka. As he grew up, Yoshitaka guided his clan through the Manji War, strategically siding with Kanbe Tomoyoshi when the latter landed in Kagoshima in opposition to Azuchi. He would come to rule over a rejuvenated domain at its most cohesive and prosperous in decades, trade flowing through the Kanmon Straits and the Yamao Church at a historical peak.
