Chiyoda (Japanese: 千代田区, Hepburn: Chiyoda-ku; IPA: [tɕijoda] ), a.k.a. Chiyoda City in English, is a special ward of Tokyo, Japan. Located in the heart of Tokyo's 23 special wards, Chiyoda consists of the Imperial Palace and a surrounding radius of about a kilometer (1000 yards), and is known as the political and financial center of Japan. As of October 2020, the ward has a population of 66,680, and a population density of 5,709 people per km (14,786 per sq. mi.), making it by far the least populated of the special wards. The residential part of Chiyoda is at the heart of Yamanote, Tokyo's traditional upper-class residential area, with Banchō, Kōjimachi, and Kioichō considered the most exclusive neighbourhoods in the entire city. The total area is 11.66 km (4½ sq. mi.), of which the Imperial Palace, Hibiya Park, National Museum of Modern Art, and Yasukuni Shrine take up approximately 2.6 km (1 sq. mi.), or 22%.

Chiyoda is known as the economic center of Japan; the districts of Otemachi, Marunouchi and Yurakucho east of the palace (an area colloquially known as "Daimaruyu") house the headquarters of 19 Fortune 500 companies, is the source of roughly 10% of the combined revenue of all Japanese companies, and produced the equivalent of around a quarter of the country's GDP in 2017. With a day population of around 850,000, its day/night population ratio is by far the highest of all municipalities in Japan. Tokyo Station, Tokyo's main inter-city rail terminal and the busiest train station in Japan in terms of scheduled trains, is also located in Chiyoda.

In philosophy and theology, metempsychosis (Ancient Greek: μετεμψύχωσις) is the transmigration of the soul, especially its reincarnation after death. The term is derived from ancient Greek philosophy, and has been recontextualized by modern philosophers such as Arthur Schopenhauer, Kurt Gödel, Mircea Eliade, and Magdalena Villaba; otherwise, the word "transmigration" is more appropriate. The word plays a prominent role in James Joyce's Ulysses and is also associated with Nietzsche. Another term sometimes used synonymously is palingenesis.

The National Crafts Museum (国立工芸館, Kokuritsu Kōgei Kan) is a museum of Japanese crafts in Kanazawa, Ishikawa Prefecture, Japan. Still retaining the more formal, official designation National Museum of Modern Art, Tokyo Craft Gallery (東京国立近代美術館工芸館), it forms part of the Independent Administrative Institution National Museum of Art (ja). As part of the government policy of regional revitalization, the facility relocated in 2020 from Kitanomaru Park in Tokyo, where it first opened in 1977. It is now housed in two Western-style buildings of the Meiji period that have themselves been relocated from elsewhere in Kanazawa, reassembled, and restored, the 1898 Old 9th Division Command Headquarters and 1909 Old Army Generals Club. From the collection of some 3,800 items, by craftsmen from all over Japan, some 1,900 have been transferred, including approximately 1,400 by "holders" and preservers of Important Intangible Cultural Properties, who are often referred to as "Living National Treasures", and members of the Japan Art Academy.

Kitanomaru Park (北の丸公園, Kitanomaru Kōen) is a public park in Chiyoda, central Tokyo, Japan, just north of the Tokyo Imperial Palace. It is the location of the Nippon Budokan indoor sports and performance venue, the Science Museum, and the National Museum of Modern Art, Tokyo.

Metempsychosis (生々流転, Seisei ruten), alternatively translated as The Wheel of Life, is a painting by Japanese Nihonga artist Yokoyama Taikan. First displayed at the tenth Inten exhibition in 1923, it forms part of the collection of the National Museum of Modern Art, Tokyo, and has been designated an Important Cultural Property.
