Yonezawa Castle

Overview

Yonezawa Castle (米沢城, Yonezawa-jō) is a flatland castle in the centre of Yonezawa, a city in southern Yamagata Prefecture. Its first construction is dated to 1238, in the Kamakura period (1185–1333), making it one of the older castle sites in the Tōhoku region. For most of the Edo period it was the seat of the Uesugi clan, the daimyō (大名, feudal lords) of Yonezawa Domain. The site is listed among the Continued Top 100 Japanese Castles, a selection of historic castle sites maintained for preservation and public visiting.

History

The castle was founded in 1238, the first year of the Ryakunin era (暦仁), during the Kamakura period. In that year the shogunate's reach into the northern provinces was still being consolidated, and castles of this kind were administrative and military strongholds rather than the stone-walled fortresses of later centuries.

The site's best-known association is with Date Masamune (伊達政宗), the Date clan lord who was born at Yonezawa Castle. Masamune went on to become one of the most powerful daimyō of the late sixteenth and early seventeenth centuries, based at Sendai. The Date held Yonezawa before their move north.

In the Edo period the castle passed to the Uesugi clan, who made it the headquarters of Yonezawa Domain (米沢藩) and ruled from it for the rest of the period. The Uesugi were descended from Uesugi Kenshin, the celebrated Sengoku-period general, and their transfer to Yonezawa made the castle the political centre of the domain.

What Stands There Today

The castle site lies in the middle of Yonezawa. Its moats and earthworks survive in the form of a park, and the grounds are planted with cherry trees that draw visitors in spring. The site's inclusion in the Continued Top 100 Japanese Castles reflects its standing as a preserved historic location rather than a reconstructed keep.

The Name in Japanese

The castle's name is written 米沢城. In kana it is よねざわじょう, and in romaji it is Yonezawa-jō.

The name breaks down into three characters:

• 米 — read こめ (kome) here, meaning "rice". This is the same character used for "rice" in everyday Japanese and for "America" (米国, beikoku) in news writing.
• 沢 — read ざわ (zawa) here, meaning "marsh" or "swamp". The character's basic reading is さわ (sawa); it shifts to zawa when it follows another element in a compound, a common sound change called rendaku (連濁, sequential voicing).
• 城 — read じょう (jō) here, meaning "castle". This is the standard suffix for castle names across Japan, as in 大阪城 (Ōsaka-jō) and 姫路城 (Himeji-jō).

So the name means, roughly, "Rice Marsh Castle" — a place name describing wet lowland, with the castle suffix attached. The same 米沢 spelling is the name of the city, and the castle takes its name from the place.

Visiting and Context

Yonezawa sits in a basin surrounded by mountains in southern Yamagata Prefecture, on the Yamagata Shinkansen line, which puts it within day-trip range of Tokyo and Sendai. The castle park is in the city centre, close to the station area, and is free to walk through.

The city's other major draw is the Uesugi connection: the Uesugi Shrine and the nearby museums hold material relating to the clan and to Uesugi Kenshin, whose memory the domain's lords carried with them to Yonezawa. For readers studying Japanese, the site is a useful case study in how place names work — a descriptive geographic name (rice marsh) plus the castle suffix 城, with a sound change in the middle element that is easy to miss on first reading.
