Gusuku (ぐすく, 城, Okinawan: gushiku)[1] often refers to Okinawan castles or fortresses that feature stone walls. However, the origin and essence of gusuku remain controversial. In the archaeology of Okinawa Prefecture, the Gusuku period refers to an archaeological epoch of the Okinawa Islands that follows the shell-mound period and precedes the Ryūkyū Kingdom. Many gusuku and related cultural remains in Okinawa Island have been listed by UNESCO as World Heritage Sites under the title Gusuku Sites and Related Properties of the Kingdom of Ryukyu.

Philological analysis

Shuri Castle, rebuilt after WWII

In the Omoro Sōshi, the term gusuku is written as "くすく," or "ぐすく" in hiragana. Occasionally, the kanji "城" (castle) is assigned to it. This is an unusual kun reading as it is pronounced shiro in standard Japanese. In later Ryūka and Kumi Odori, the reading shiro is also used for the same kanji.[2]

In the Omoro Sōshi, the referents of gusuku are mostly castles and fortresses but are not limited to them. Some are sacred places and places of worship. In some cases, gusuku refers to Shuri Castle. The Liuqiu-guan yiyu, a Chinese dictionary, maps Chinese "皇城" (imperial palace) to the transcription "姑速姑" (gu-su-gu). Similarly, the Yiyu yinshi assigns "窟宿孤" (ku-su-gu) to "皇城."[2]

Etymology

There is no consensus about the etymology of gusuku. Chamberlane analyzed the word as the combination of gu (< honorific go 御) and shuku (宿). Kanazawa Shōzaburō also segmented gusuku into gu and suku but considered that the latter half was cognate with old mainland Japanese shiki, in which ki was a loan from some Old Korean language. Iha Fuyū proposed that suku was cognate with soko (塞, fortress). Hirata Tsugumasa considered that suku was cognate with mainland Japanese soko (底, bottom).[3]

Higashionna Kanjun raised doubts over the analysis of gu since older records always used honorific u (< o) instead of gu (< go). Nakahara Zenchū identified gu as go (stone).[3]

Gusuku controversy

Although it is widely recognized in the Okinawa Islands that gusuku are castles/fortresses, there is ample reason to question this perception. The origin and essence of gusuku were actively discussed in the 1960s and 70s and remain controversial.

Cultural geographer Nakamatsu Yashū claimed that the essence of gusuku was a sacred place. His theory was backed by decades of field work that was not limited to the Okinawa Islands but that extended to Amami, Miyako and Yaeyama. He revealed that an overwhelming majority of what were called gusuku by local communities did not look like castles or fortresses at all. In fact, they were too isolated from local communities, too small to live in and lacked water supply. Among hundreds of gusuku, only a dozen were fortifications. Each community usually had a gusuku. Gusuku were typically located on hills, but some were on sand dunes, on cliff edges, and in caves. In some communities, what were called gusuku were actually stone tombs. Nakamatsu explained the great diversity of gusuku by one feature in common: sacredness. According to Nakamatsu, a gusuku was in origin a place of "aerial burial." The reason that a dozen of gusuku were transformed into fortress/castle-like structures is unclear, but he conjectured that some rulers had expanded gusuku substantially by building their family residences around them. Shuri Castle, the largest gusuku, encompasses sacred places such as Sui mui gusuku and Madan mui gusuku, which suggests the original nature of the castle.[4][5]

Archaeologists from Okinawa Prefecture have labeled some archaeological findings as gusuku. Takemoto Masahide claimed that gusuku were defensive communities. He classified what he considered gusuku into three types:

  • A: residence of political leaders, a fortress/castle with stone walls,
  • B: defensive community, and
  • C: place of ancestor worship or burial place.

According to Takemoto, Type B, which is overwhelming in number, appeared during the transitional period between primitive society and class society.[6] As noted by Asato Susumu, there is a significant gap in the use of the term gusuku. While Nakamatsu referred to limited space as gusuku, Takamoto applied the term to the whole archaeological site.[7]

Archaeologist Tōma Shiichi hypothesized that a gusuku was the residence of an aji (local ruler) and his family. Since most gusuku in the Okinawa Islands are accompanied with stone walls, he considered that the Gusuku Period was characterized by the formation of class society. Among archaeologists, however, Kokubu Naoichi supported Nakamatsu's theory considering poor living conditions of gusuku.[6] Asato Susumu expressed concern about the association of gusuku with class society because the emergence of political rulers was not well attested by archaeological findings but mostly based on literature that was written centuries later.[7]

In any case, a flood of archaeological discoveries in the 1970s led Okinawan archaeologists to establish archaeological periods of the Okinawa Islands that were distinct from those of mainland Japan (also different from those of Amami, Miyako, and Yaeyama). In their framework, the Gusuku period is an archaeological epoch of the Okinawa Islands, in which they consider is featured by gusuku, the widespread use of iron and farming. It follows the Shell Mound period and precedes the Ryūkyū Kingdom. It is parallel with the late Heian to Muromachi periods of mainland Japan. Also, the beginning of the Gusuku period roughly corresponds to that of the Old Ryukyu period of Okinawan historiography.

Takanashi Osamu, an archaeologist from the Amami Islands, Kagoshima Prefecture, criticized the trend of Okinawan archaeology. The Gusuku period lacked clear makers of dating. Pottery seriation, in particular, remained poorly understood. The contemporaneousness of stone walls and excavated potteries was not established. He also noted a bias of Okinawan archaeologists, who he thought were preoccupied with questions of how the Okinawa-centered kingdom of Ryūkyū was formed.[8][9]

While typical castle/fortress-type gusuku in the Okinawa Islands were featured by stone walls, it was discovered in the 1980s and 90s that some fortifications in northern Okinawa Island lacked stone walls but instead were characterized by earthworks, kuruwa and dry moats. This style of fortifications is in fact rather common in Amami Ōshima and representative of medieval mountain fortifications (中世山城) of mainland Japan. Naka Shōhachirō and Chinen Isamu, a historian and an archaeologist from Okinawa dated them to the late 12th to early 13th centuries and claimed that they were predecessors of gusuku with stone walls.[10] This view was actively criticized by Takanashi Osamu in the late 1990s and 2000s.[8][9]

Miyako and Yaeyama

Archaeological studies in the southern island groups of Miyako and Yaeyama are not so active as those in the Okinawa Islands. Some Okinawa-led archaeological reports labeled some sites in Miyako and Yaeyama as "gusuku-like." Archaeologist Ono Masatoshi raised concern about the naïve application of the Okinawan gusuku-as-fortifications framework and urged that scholars should not turn a blind eye to the diversified nature of archaeological sites with stone walls in these islands.[11]

Linguist Nakamoto Masachie noted that in some dialects of Yaeyama, gusuku/gusïku means stone walls themselves and conjectured that this might be the original meaning of gusuku.[12] According to Ono Masatoshi, gusuku has various meanings, depending on dialects of Yaeyame, including a partition of a mansion and stone walls surrounding an agricultural field.[11] Nakamatsu Yashū claimed that suku-like word forms were more prominent in Miyako and Yaeyama than gusuku.[5]

Regardless of whether it is appropriate to call them gusuku, the Miyako Islands have archaeological remains with stone walls, such as Mashuku Village of Hateruma Island, Hanasuku and Gumāra Villages and Shinzato Villages of Taketomi Island. They were villages abandoned around the time of the conquest by the Ryūkyū Kingdom. What are common to these villages are that they were located on top of cliffs, divided by inhomogeneous cell blocks and lacked roads. The whole village and each cell block were surrounded by stone walls.[11] This type of abandoned settlements can also be found in Miyako Island but they are rather exceptional.[13] The local people call these remains busu nu yashiki (bushi's mansion), busu nu yā ishigaki (bushi's house's stone walls) or busu nu yā (bushi's house), busu nu yama (bushi's mountain) in Ishigaki, bushiN yā (bushi's house) in Hatoma, nishi nu bushi nu yā (bushi's house in the west) in Aragusuku.[14]

In the archaeology of Yaeyama, human settlements prior to the conquest by the Ryūkyū Kingdom are called "Suku Villages" probably because the names of these remains have the suffix -suku.[15] By extension, the archaeological epoch of the Suku Culture (11-16th centuries) is sometimes used by archaeologists.[14]

Amami

Formal studies of gusuku in the northern island group of Amami were started by Nakamatsu Yashū in the 1960s and 70s. He revealed that most of what were called gusuku by local communities of Amami were by no means fortifications. He also noted that Amami has -suku toponyms, which were otherwise considered specific to Miyako and Yaeyama.[4] However, his study on Amami went largely unnoticed.[8]

In 1980s and 90s, Miki Yasushi, an expert of medieval mountain fortifications of mainland Japan, extended his research to the Amami Islands, largely independently of Okinawan archaeology.[16] His comprehensive study found 129 gusuku toponyms in Amami Ōshima. Similarly, a 1982 research project by Kagoshima Prefecture covered 45 fortifications in Amami.[8] Miki carefully noted that, as Nakamatsu shown, most of what were called gusuku were not fortifications, and that conversely, some fortifications were not called gusuku by the locals. A major difference from those in the Okinawa Islands was that gusuku in Amami (except those in Okinoerabu and Yoron) nearly completely lacked stone walls. As a historian from mainland Japan, Miki took much notice of the religious nature of gusuku in Amami, which is completely absent from mainland Japanese fortresses.[16]

Publications from Amami gained attention of some Okinawan archaeologists in 1980s and 90s, and they attempted to place Amami's gusuku in the Okinawan gusuku-as-fortifications framework. Naka Shōhachiro investigated some gusuku in Amami Ōshima and discovered kuruwa and dry moats there. He claimed that the primary function of those gusuku was defensiveness, not religiousness as Nakamatsu claimed. He dated them to the late 12th to early 13th centuries and considered that they subsequently evolved into those with stone walls in Okinawa.[8] By contrast, Miki conjectured that the construction of these fortifications was triggered by repeated invasion by the Okinawa-centered kingdom of Ryūkyū in the 15th and 16th centuries.[16]

In his survey of earlier studies, Takanashi Osamu criticized Naka's theory because his dating lacked evidence. In fact, gusuku with established dates were mostly from the 14th to 16th centuries. While other archaeologists had focused on mountain fortifications, he paid attention to gusuku in flat land. He also indicated the possible presence of gusuku in the Tokara Islands, which are located to the north of Amami.

From 1995 to 2000, a comprehensive investigation of gusuku was conducted in Naze (merged into the city of Amami in 2006) of northern Amami Ōshima. This project initially relied on gusuku toponyms to find archaeological remains but discovered far more remains in the mountains than expected. Among 45 sites discovered, only five had gusuku toponyms. This suggests that these sites were not gusuku in origin and that some of them were later transformed into gusuku. The toponymic survey also found that some earlier archaeological reports had labeled gusuku even though the referents were not called gusuku by locals. As a result, so-called "Uragami Gusuku", for example, was renamed to "Uragami-Arimori site."[9]

Earlier studies pointed to the similarity between gusuku in Amami and northern Okinawa Island and medieval mountain fortifications of mainland Japan. Takanashi went further claiming that these fortifications were in fact medieval mountain fortifications. He considered the possibility that there were gaps in time among (1) the beginning of the archaeological sites, (2) the construction of defensive structures and (3) the applications of the name of gusuku. He re-evaluated Nakamatsu's sacredness theory and presented a working hypothesis that gusuku in Amami were of secondary origin, possibly related to the introduction of the noro ritual system by the Ryūkyū Kingdom.[9]
