Some medicines such as the cancer drug trabectedin are based on toxins or other molecules of animal origin.
The Jinshin War of 672, a bloody conflict between Prince Ōama and his nephew Prince Ōtomo, became a major catalyst for further administrative reforms. The true aim of the reforms was to bring about greater centralization and to enhance the power of the imperial court, which was also based on the governmental structure of China. It nationalized all land in Japan, to be distributed equally among cultivators, and ordered the compilation of a household registry as the basis for a new system of taxation.

• Extant phyla in these rocks include molluscs, brachiopods, onychophorans, tardigrades, arthropods, echinoderms and hemichordates, along with numerous now-extinct forms such as the predatory Anomalocaris.
• Some benthic animals living close to hydrothermal vents and cold seeps on the dark sea floor consume organic matter produced through chemosynthesis (via oxidising inorganic compounds such as hydrogen sulfide) by archaea and bacteria.
• The country has therefore aimed to diversify its sources and maintain high levels of energy efficiency.
• Animals may be listed or indexed by many criteria, including taxonomy, status as endangered species, their geographical location, and their portrayal and/or naming in human culture.
• In 1874, Ernst Haeckel divided the animal kingdom into the multicellular Metazoa (now synonymous with Animalia) and the Protozoa, single-celled organisms no longer considered animals.

Once considered the strongest in the world, the Japanese consumer electronics industry is in a state of decline as regional competition arises in neighboring East Asian countries such as South Korea and China. The country’s manufacturing output is the third highest in the world as of 2023update. Japan maintains one of the world’s largest fishing fleets and accounts for nearly 15% of the global catch, prompting critiques that Japan’s fishing is leading to depletion in fish stocks such as tuna. The Japanese agricultural sector accounts for about 1.2% of the country’s total GDP as of 2018update.

Species estimates shown here are based on numbers described scientifically; much larger estimates have been calculated based on various means of prediction, and these can vary wildly. Other animals may have very specific feeding behaviours, such as hawksbill sea turtles which mainly eat sponges. In sponges, blastula larvae swim to a new location, attach to the seabed, and develop into a new sponge. Japan is the most successful Asian Rugby Union country and hosted the 2019 IRB Rugby World Cup. The country gained the hosting rights for the official Women’s Volleyball World Championship on five occasions, more than any other country.
For instance, around 25,000–27,000 species of nematodes have been described, while published estimates of the total number of nematode species include 10,000–20,000; 500,000; 10 million; and 100 million. The following table lists estimated numbers of described extant species for the major animal phyla, along with their principal habitats (terrestrial, fresh water, and marine), and free-living or parasitic ways of life. The blue whale (Balaenoptera musculus) is the largest animal that has ever lived, weighing up to 190 tonnes and measuring up to 33.6 metres (110 ft) long. Vertebrates such as the lobe-finned fish Tiktaalik started to move on to land in the late Devonian, about 375 million years ago. Some benthic animals living close to hydrothermal vents and cold seeps on the dark sea floor consume organic matter produced through chemosynthesis (via oxidising inorganic compounds such as hydrogen sulfide) by archaea and bacteria.

• In the classical era, Aristotle divided animals,d based on his own observations, into those with blood (roughly, the vertebrates) and those without.
• On March 11, 2011, Japan suffered the Tōhoku earthquake—the largest by magnitude in its recorded history—which, along with the ensuing tsunami, triggered the Fukushima nuclear accident.
• The northernmost region, Hokkaido, has a humid continental climate with long, cold winters and very warm to cool summers.
• Since then, the last four have all been subsumed into a single phylum, the Chordata, while his Insecta (which included the crustaceans and arachnids) and Vermes have been renamed or broken up.
• On April 1, 2019, Japan enacted its revised immigration law, protecting the rights of foreign workers to help reduce labor shortages in certain sectors.

Red-Billed Quelea Bird

The scarab beetle was sacred in ancient Egypt, and the cow is sacred in Hinduism. People have used hunting dogs to help chase down and retrieve animals, and birds of prey to catch birds and mammals, while tethered cormorants have been used to catch fish. The protostomes include the Ecdysozoa, named after their shared trait of ecdysis, growth by moulting, Among the largest ecdysozoan phyla are the arthropods and the nematodes. The remaining animals, the great majority—comprising some 29 phyla and over a million species—form the Bilateria clade, which have a bilaterally symmetric body plan.

It consists of a lower House of Representatives with 465 seats, elected by popular vote every four years or when dissolved, and an upper Senate with 248 seats, whose popularly elected members serve six-year terms. More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, which triggered a large tsunami. From the 12th century, actual power was held by military aristocrats known as shōgun and feudal lords called daimyō, enforced by warrior nobility named samurai.
Having a front end means that this part of the body encounters stimuli, such as food, favouring cephalisation, the development of a head with sense organs and a mouth. The digestive chamber has two openings, a mouth and an anus, and in the Nephrozoa there is an internal body cavity, a coelom or pseudocoelom. Most members of Medusozoa, including jellyfish and most hydrozoans, have a basswin polyp form as well, but also have a motile medusae stage. Members of the group Anthozoa, such as sea anemones, coral, and sea pens only are sessile polyps. Sponges lack the complex organisation found in most other animal phyla; their cells are differentiated, but in most cases not organised into distinct tissues, unlike all other animals.
After being defeated in the Pacific War and suffering the U.S. atomic bombings of Hiroshima and Nagasaki, Japan surrendered in 1945 and came under Allied occupation until 1952. The Meiji period saw Japan pursue rapid industrialization, modernization, militarism, and overseas colonization. Between the 4th and 6th centuries, its kingdoms were united under an emperor in Nara and later in Heian-kyō. With a population of almost 123 million as of 2026, it is the world’s 11th most populous country.

Crappie Fish

Japan ranked seventh in the world in tonnage of fish caught and captured 3,167,610 metric tons of fish in 2016, down from an annual average of 4,000,000 tons over the previous decade. As the central coordinating body for the Prefectural Police Departments, the National Police Agency is administered by the National Public Safety Commission. The deployment of troops to Iraq and Afghanistan marked the first overseas use of Japan’s military since World War II. The country’s military, the Japan Self-Defense Forces (JSDF), is restricted by Article 9 of the Japanese Constitution, which renounces Japan’s right to declare war or use military force in international disputes. Japan is widely considered to be a great power due to its economic power and political, cultural, and military influence. The broadly conservative Liberal Democratic Party has been the dominant party in the country since the 1950s, often called the 1955 System.
