GojūonIn the Japanese language, the 五十音 is a traditional system ordering kana characters by their component phonemes, roughly analogous to alphabetical order. The "fifty" (gojū) in its name refers to the 5×10 grid in which the characters are displayed. Each kana, which may be a hiragana or katakana character, corresponds to one sound in Japanese. As depicted at the right using hiragana characters, the sequence begins with あ (a), い (i), う (u), え (e), お (o), then continues with か (ka), き (ki), く (ku), け (ke), こ (ko), and so on and so forth for a total of ten rows of five columns.
Tōyō kanjiThe tōyō kanji, also known as the tōyō kanjihyō (当用漢字表, "list of kanji for general use") are the result of a reform of the Kanji characters of Chinese origin in the Japanese written language. They were the kanji declared "official", i.e. characters that could be used in official government documents, by the Japanese Ministry of Education on November 16, 1946. The 1,850-character list was not meant to be exhaustive, as many characters that were in common use at the time, and are today, were not included.
Jōyō kanjiThe jōyō kanji is the guide to kanji characters and their readings, announced officially by the Japanese Ministry of Education. Current jōyō kanji are those on a list of 2,136 characters issued in 2010. It is a slightly modified version of the tōyō kanji, which was the initial list of secondary school-level kanji standardized after World War II. The list is not a comprehensive list of all characters and readings in regular use; rather, it is intended as a literacy baseline for those who have completed compulsory education, as well as a list of permitted characters and readings for use in official government documents.
Heavenly StemsThe ten Heavenly Stems or Celestial Stems () are a Chinese system of ordinals that first appear during the Shang dynasty, c. 1250 BCE, as the names of the ten days of the week. They were also used in Shang-period ritual as names for dead family members, who were offered sacrifices on the corresponding day of the Shang week. The Heavenly Stems were used in combination with the Earthly Branches, a similar cycle of twelve days, to produce a compound cycle of sixty days.
Khitan small scriptThe Khitan small script () was one of two writing systems used for the now-extinct Khitan language (the other was the Khitan large script). It was used during the 10th–12th century by the Khitan people, who had created the Liao Empire in present-day northeastern China. In addition to the small script, the Khitans simultaneously also used a functionally independent writing system known as the Khitan large script. Both Khitan scripts continued to be in use to some extent by the Jurchens for several decades after the fall of the Liao dynasty, until the Jurchens fully switched to a script of their own.
Kōjien広辞苑 is a single-volume Japanese dictionary first published by Iwanami Shoten in 1955. It is widely regarded as the most authoritative dictionary of Japanese, and newspaper editorials frequently cite its definitions. As of 2007, it had sold 11 million copies. Kōjien was the magnum opus of Shinmura Izuru, 1876–1967, a professor of linguistics and Japanese at Kyoto University. He was born in Yamaguchi Prefecture and graduated from the prestigious Tokyo University, where he was a student of Kazutoshi Ueda.
OrigamiOrigami) is the Japanese art of paper folding. In modern usage, the word "origami" is often used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word to refer to designs which use cuts.
