What does Shinanomachi mean?


(Shinano Town)


Today’s place name is really easy, so I thought I’d take a little time to review some ideas that pop up from time to time. Hopefully this is a good refresher for long time readers and a way to bring new readers up to speed.

I’m constantly referring to a variety of administrative units and geographical areas, most commonly: 国 kuni provinces, 藩 han domains, 郡 gun districts, 村 mura villages, and 町 machi towns. The meanings of these terms changed over time. Since JapanThis! tends to focus on 江戸東京 Edo-Tōkyō, the last term 町 machi generally referred to tightly controlled towns made up of commoners or low ranking samurai that centered around a specific trade or activity. 郡 gun districts and 村 mura villages were more loosely defined and referred to larger areas with a less cohesive concentration of residences – districts being much, much larger than villages, naturally[i]. The first two terms, 国 kuni and 藩 han are a bit more specialized.

kuni, koku


令制国 ryōsei koku administrative provinces (also called 律令国 ritsuryō koku) were established sometime between 645 and 701. This is the birth of the “province.”

 During the Muromachi Period, the large provincial territories came to be superseded by the protectorates of 守護大名 shugo daimyō (for lack of a better translation, “military governors/protectors of specific fiefs”).

By the time of 豊臣秀吉 Toyotomi Hideyoshi, the ancient provinces were merely archaic boundaries on the map. Actual political authority was held by daimyō over their lands, ancestral or recently acquired. This situation continued through the Edo Period – the real power being controlled by local daimyō whose fiefs were now called 藩 han domains.

After the rise of the han system, the provinces existed as geographical borders – but not political borders – until 1871 when the imperial edict 廃藩置県 haihan-chiken was promulgated. The name means “abolition of domains, establishment of prefectures.” [ii]Today provincial names are used as nostalgic nicknames.

kokushi, kuni no tsukasa
provincial governors

Governor is a somewhat weak translation, but it’s good enough for our purposes. But in short, with the establishment of provinces, kokushi were the officials granted control the provinces. The position weakened in the Kamakura and Muromachi Periods.

Kokushi titles came in 4 flavors. They consisted of a province name plus a rank. From highest to lowest, those ranks were 守 kami protector, 介 suke caretaker, 掾 jō officer, 目 sakan overseer[iii]. (The translations of those kanji are my own and just meant to give my non-kanji reading readers a general idea.)

As the geopolitical importance of provinces faded away, kokushi titles became mere courtly titles. In the Edo Period, these archaic titles were prestigious in the courts of the shōgun and emperor, but the people bearing the titles wielded no power over the territory. It was strictly a formality.

So why did I bother going through all of that? Well, as I said before, it never hurts to review a few important concepts. Also, there are new readers joining all the time and I want to make sure they’re all onboard. And lastly, the concept of 国司 kokushi is important to this place name.

信濃国 Shinano no Kuni[iv] Shinano Province was located inside present day 長野県 Nagano-ken Nagano Prefecture. The name of 信濃町 Shinanomachi is derived from this place name and is connected with the kokushi title 信濃守 Shinano no Kami Protector of Shinano.

Shinanomachi is located in Shinjuku Ward.

“Why have I never heard of this place?” you’re probably asking yourself.
Simple, no one fucking lives there. As of 2010, the area claimed to house a mere 979 residents!!

So, Whose Title Was This?

永井尚政 Nagai Naomasa was a daimyō who was active at the dawn of the Edo Period. He was born in 1587; the same year 豊臣秀吉 Toyotomi Hideyoshi began expelling Christians from Japan. His father, 永井直勝 Nagai Naokatsu, was a retainer of 徳川家康 Tokugawa Ieyasu. As such Naomasa was along for the ride at many of the major events that catapulted Ieyasu to the position of shōgun – ie; the military campaigns that defined both the beginning of the shōgunate and the end of the Sengoku Period.

In 1600, at the ripe old age of 13, Naomasa is believed to have accompanied his father Naokatsu to the 関ケ原の戦い Sekigahara no Tatakai Battle of Sekigahara. In 1602, he became an attendant of 徳川秀忠 Tokugawa Hidetada, who would soon become the 2nd shōgun. Needless to say, this was an extremely prestigious position for a boy of his age.

A famous screen depicting the Battle of Sekigahara. I actually recently saw the real thing at the Great Sekigahara Exhibit at the Edo-Tokyo Museum. It was pretty freaking impressive.

In 1605, the newly installed 2nd shōgun, Hidetada, granted him the honorary title 信濃守 Shinano no Kami. Having received this title directly from the shōgun, this new name became far more well-known than his real name. However, his new status within the shōgunate ranks came with responsibilities and so from winter 1614 to spring 1615, he fought alongside the retired shōgun Ieyasu and shōgun Hidetada at the 大坂の陣 Ōsaka no Jin Siege of Ōsaka. Years later, the 3rd shōgun, Tokugawa Iemitsu sent him to protect the imperial city of 京都 Kyōto during the 島原の乱 Shimabara no Ran Shimabara Rebellion from winter 1637 to spring 1638[v]. These last 2 campaigns are often said to have put out the last serious threats to Tokugawa hegemony.

In his career as a chief retainer of the first 4 Tokugawa shōguns[vi], Shinano no Kami’s life spanned the last gasps of the Sengoku Period and saw the birth of the so-called Pax Tokugawa[vii]. The shōgunate changed his domains 3 times, which meant his status as a daimyō was elevated 3 times.

The term attendant (koshō, in Japanese) is actually a somewhat erotically charged term. But to the best of my knowledge Hidetada didn't have an established sexual relationship with Naomasa. He probably just acted as an assistant and secretary.

OK, this guy is cool and all, but why is there a place in Tokyo called Shinanomachi?

According to the rules of 参勤交代 sankin-kōtai alternate attendance[viii], Nagai Naomasa (Shinano no Kami) was required to build 3 palaces in the shōgun’s capital at Edo. He built his下屋敷 shimo-yashiki lower residence[ix] in an area between modern Shinanomachi and 四ツ谷 Yotsuya. The title Shinano no Kami was hereditary and since all of the daimyō living in that palace were called Shinano no Kami (and indeed, this title is written on maps, not Nagai), it’s clear the local economy that popped up to service the Nagai daimyō and their retainers came to be called 信濃町 Shinano Machi “Shinano Town.”

Spoiler alert.  Nagai Naomasa becomes a monk.

Nagai Naomasa’s Final Days

In 1632, shōgun Hidetada died, and Naomasa was one of the daimyō in charge of overseeing the construction of the lavish funerary temple, 台徳院 Daitoku-in[x] at the Tokugawa 菩提寺 bodai-ji, family temple 増上寺 Zōjō-ji in 芝 Shiba[xi]. By the time of his retirement in 1658, his imperial court rank had been raised from 従五位下 ju go’i no ge Lower Junior 5th Rank to 従四位下 ju shi’i no ge Lower Junior 4th Rank[xii]. After retirement he became a Buddhist monk and changed his name to 信斎 Shinsai which means “holy truth” but preserves the first kanji from his courtly title. He eventually died in 1668 and then his body was interred at 興聖寺 Kōshō-ji Kōshō Temple in Kyōto.

In the popularized tales of samurai lore, Nagai Naomasa isn’t particularly well known. But I think you can appreciate that he was living in one of the most exciting times a Sengoku samurai could have lived in. He lived through the very tail end of the Sengoku Period – and definitely witnessed and participated in warfare. But he also lived to be an old man who saw the most stable regime anyone had seen in 100 years. It reminds me of the scene in Game of Thrones, where Bronn says “I’ve had an exciting life. I want my death to be boring.” Naomasa was of the first generation that made that dream a reality. He had grown up in a time full of violence but the dawn of the new age had afforded him the luxury of dying a peaceful death. Such a death was a luxury that would become a norm for the samurai of the Edo Period.

[i] 郡 gun is sometimes translated as “county.”
[ii] By the way, why does Japan have prefectures and not states?
[iii] Two famous examples from the Edo Period are 吉良義央 Kira Yoshihisa – usually portrayed as the villain in the 47 Rōnin story – whose titles was 上野介 Kōzuke no Suke Guardian of Kōzuke Province – and 勝海舟 Katsu Kaishū – whose title was 阿波守 Awa no Kami Protector of Awa Province.
[iv] The short name for the province was 信州 Shinshū. By the way, the kanji for Shinano – like most provincial names – is most likely ateji. That is to say, there is no meaning.
[v] We talked about the Shimabara Rebellion the other day in my article on Fuda no Tsuji.
[vi] Ieyasu, Hidetada, Iemitsu, Ietsuna.
[vii] A pseudo-Latin term that means “Tokugawa Peace” based on the real Latin term Pax Romana “Roman Peace” – referring to the establishment of the Roman Empire under Augustus Caesar.
[viii] You should probably know the basics of alternate attendance.
[ix] A daimyō’s lower residence was often the largest estate. It was generally suburban and served as a refuge in case of disaster or if said daimyō just needed to get away from it all.
[x] Sometimes Romanized as Taitoku-in. Here’s my article about it.
[xi] Hidetada’s mortuary temple was one of the grandest examples of Edo Period funerary architecture, next to the mausolea in Nikkō, was probably one of the most unique graves of a Tokugawa Shōgun – without a doubt, it was the greatest example in Edo itself.
[xii] Don’t even ask me to explain the court rank system. I can’t! lol

  1. That temple is BEAUTIFUL!!

    I just moved to Japan and I live in Shinjuku. How far is it from the station. I’d love to check it out.


  2. Marky-san, This is so informative!
    I was given the link to your article by Eric over at the Japan Castles fb group. I live in Nagano (aka Shinano) and has been curious about why there’s a Shinanomachi in Tokyo.
    Can I ask a few follow up questions?
    When you say “Hidetada, granted him the honorary title 信濃守 Shinano no Kami” does that mean Nagai Naomasa was the honorary governor of Shinano Province?
    And with Sankin Koutai you mention he was required to maintain 3 palaces in Edo? I thought it meant spending half the year away in the province and the other half at a residence maintained in Edo. Would Shinanomachi be the neighborhood that grew up around the Shinano-no-Kami’s residence in Edo?
    One last question: What brought this up was I happened to visit Takiyama Castle in Hachioji and saw a sign for 信濃曲輪 Shinano Bailey. Do you by chance know the story behind that name? i.e. Any connection with Shinanomachi or Shinano Province?
