Detailed Country Guide
Overview and identity
Japan, officially listed here as Japan, is structured as a practical country reference guide for users searching country facts, maps, flags, codes, and daily-use data. The page should make Japan, JP, JPN, the flag, the official name, and the country slug easy to confirm because users often land on country pages while checking identifiers for forms, travel, education, or data products. Japan is grouped under Asia, more specifically Eastern Asia, with Asia shown as the continent context.
Geography and population scale
The country dataset records a population of 122,950,000 people and a land area of 377,930 square kilometers, which gives an approximate density of 325 people per square kilometer. The main coordinate reference is 36, 138, while the capital coordinate reference is 35.68, 139.75. Japan has no land borders listed in the country data, and the landlocked value is recorded as no. These details help the page answer common searches around location, area, borders, map position, and population comparison.
Capital and urban network
The capital information is recorded as Tokyo (primary). The largest city entries shown for this country are Tokyo, Ōsaka, Nagoya, Yokohama and Fukuoka. Including cities alongside country-level facts helps the guide answer searches such as largest cities in Japan, capital of Japan, and major urban areas in Japan. This is useful because many users compare the official capital with the largest business, transport, or population centers.
Government, classification, and memberships
The government type is listed as Unitary parliamentary constitutional monarchy. The classification fields mark sovereignty as yes, United Nations membership as yes, observer status as no, and disputed status as no. International memberships shown for this page include G20, G7, OECD and United Nations. These fields support search intent around political status, country classification, and international organization membership.
Administrative formats and daily-use data
Japan uses calling code +81, postal format ###-####, and time zone data listed as UTC+09:00. The number format uses , as the thousands separator and . as the decimal separator. The week starts on monday; the academic year starts around Apr 1; the government fiscal year starts around Apr 1; and the personal fiscal year starts around Jan 1.
Currency, language, transport, and references
Currency data lists JPY - Japanese yen (¥), while language records include Japanese. Vehicle data records the driving side as left and vehicle sign codes as J. Reference links should keep official, Wikipedia, Google Maps, and OpenStreetMap sources together when available so users can move from the structured country guide to map or source pages quickly. The latest Gini entry in the dataset is 32.3 for 2020.
How to use this profile
This Japan profile is designed to be scanned in layers: first the name, official name, flag, capital, population, area, and density; then identity, geography, cities, governance, memberships, formats, connectivity, currency, languages, transport, and references. That structure supports both human readers and product workflows where users need to verify a phone code, compare cities, inspect fiscal dates, check postal formats, review memberships, or open a map reference without searching across multiple pages.
