The Yaeyama Islands (八重山列島 Yaeyama-rettō, also 八重山諸島 Yaeyama-shotō, Yaeyama: Yaima, Yonaguni: Daama, Okinawan: Yeema, Northern Ryukyuan: やへま Yapema) are an archipelago in the southwest of Okinawa Prefecture, Japan, and cover 591.46 square kilometres (228.36 sq mi). The islands are located southwest of the Miyako Islands, part of the Ryukyu Islands archipelago. The Yaeyama Islands are the most remote part of Japan from the main islands and contain Japan's southernmost (Hateruma) and westernmost (Yonaguni) inhabited islands. The city of Ishigaki serves as the political, cultural, and economic center of the Yaeyama Islands. On maps dating to the 1700s, the Yaeyama Group of Islands appears as the "Majico Sima Group", "Nambu-soto Islands", "Nambu Soto", and the "Taipin Islands".

👉 Yaeyama Islands in the context of Papilio xuthus

Papilio xuthus, the Asian swallowtail, Chinese yellow swallowtail, Japanese Swallowtail, Korean Swallowtail or Xuthus swallowtail, is a yellow-colored, medium to large sized swallowtail butterfly found in northeast Asia, northern Myanmar, southern China, Taiwan, the Korean Peninsula, Japan (from Hokkaidō to the Yaeyama Islands), Siberia and the Hawaiian Islands. The butterfly has been observed thrice in New Zealand. Once in Dunedin in 1996 emerging from a chrysalis in a car yard specializing in Japanese used cars; it is thought the chrysalis arrived through one of the cars. and later in Auckland in 2011 and 2016. It was also recorded in the state of Arunachal Pradesh, India, in 2014.

It mates multiple times in its life, leading to an increased genetic diversity in its young. It is preyed upon by a host of organisms, including the tree cricket Oecanthus longicauda, ant Lasius niger, and wasps (Polistes and Trogus mactator). P. xuthus utilizes color vision and color constancy while foraging for plants of the family Rutaceae.

Yaeyama Islands in the context of Ryukyu Islands

The Ryukyu Islands (Japanese: 琉球列島, Hepburn: Ryūkyū Rettō), also known as the Nansei Islands (南西諸島, Nansei Shotō; lit.'Southwest Islands') or the Ryukyu Arc (琉球弧, Ryūkyū-ko), are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ryukyu Islands are divided into the Satsunan Islands (Ōsumi, Tokara and Amami) and Okinawa Prefecture (Daitō, Miyako, Yaeyama, Senkaku, Okinawa, Sakishima Islands (further divided into the Miyako and Yaeyama Islands), and Yonaguni as the westernmost). The larger ones are mostly volcanic islands and the smaller mostly coral. The largest is Okinawa Island.

The climate of the islands ranges from humid subtropical climate (Köppen climate classification Cfa) in the north to tropical rainforest climate (Köppen climate classification Af) in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs.

Yaeyama Islands in the context of Southern Ryukyuan languages

The Southern Ryukyuan languages (南琉球語群, Minami Ryūkyū gogun) form one of two branches of the Ryukyuan languages. They are spoken on the Sakishima Islands in Okinawa Prefecture. The three languages are Miyako (on the Miyako Islands) and Yaeyama and Yonaguni (on the Yaeyama Islands, of the Macro-Yaeyama subgroup). The Macro-Yaeyama languages have been identified as "critically endangered" by UNESCO and Miyako as "definitely endangered".

All Ryukyuan languages are officially labeled as dialects of Japanese by the Japanese government despite mutual unintelligibility. While the majority of Ryukyuan languages have used Chinese or Japanese script for writing, the Yaeyama Islands never had a full-featured writing system. Islanders developed the Kaidā glyphs as a simple method to record family names, items, and numerals to aid in tax accounting. This system was used until the 19th century introduction of Japanese-language education. Even today, communication in the Yaeyama or Yonaguni languages is almost exclusively oral, and written communication is done in Japanese.

Yaeyama Islands in the context of Ryukyuan music

Ryukyuan music (琉球音楽, Ryūkyū ongaku), also called Nanto music (南島歌謡, Nantō kayō), is an umbrella term that encompasses diverse musical traditions of the Amami, Okinawa, Miyako and Yaeyama Islands of southwestern Japan. The term of "Southern Islands" (南島, Nantō) is preferred by scholars in this field. The word "Ryūkyū" originally referred to Okinawa Island and has a strong association with the highly centralized Ryukyu Kingdom based on Okinawa Island and its high culture practiced by the samurai class in its capital Shuri. By contrast, scholars who cover a much broader region lay emphasis on folk culture.
