大使館
たいしかん
taishikan
= embassy
The word taishikan literally means “the mansion of an ambassador” — each kanji carries its own weight: tai (大, great), shi (使, envoy/messenger), and kan (館, building or hall). For Japanese learners, this is not just textbook vocabulary — it is the word you will actually say when you need to extend a visa or replace a lost passport abroad.
大使館 (taishikan) refers to an embassy: the official diplomatic mission that one country maintains on the soil of another. It is headed by an ambassador (taishi, 大使) and handles the full range of governmental relations between the two countries, including issuing visas, registering overseas citizens, and conducting bilateral negotiations. In everyday Japanese, the word appears in practical contexts such as taishikan ni yoru (stopping by the embassy) or taishikan ni renraku suru (contacting the embassy). The register is neutral — equally at home in conversation, news broadcasts, and formal documents.
Learners often confuse taishikan (大使館, embassy) with ryōjikan (領事館, consulate). The key difference is rank and function: an embassy is the top diplomatic mission in a country, headed by an ambassador, and there is usually only one per country. A consulate is a smaller, subordinate office — often in a major city other than the capital — that handles consular services such as visas and notarization for people in that region. When you need to renew your passport in Tokyo, you go to your country’s taishikan; when you need the same service in Osaka, you look for a ryōjikan. Also note the pitch accent: ta-i-shi-KA-n, with the accent falling on the fourth mora.
大 (dai/tai) means “large” or “great” and signals importance or seniority — the same character appears in words like daigaku (大学, university) and daijin (大臣, minister of state). 使 (shi) means “messenger” or “envoy” and shares its root with taishi (大使, ambassador). 館 (kan) denotes a substantial public building, seen also in toshokan (図書館, library) and bijutsukan (美術館, art museum). Together, the three kanji paint a precise picture: a grand building belonging to the nation’s chief envoy.

Formal / Cultural context
両国政府は大使館を通じて正式な抗議声明を交換した。
Ryōkoku seifu wa taishikan o tsūjite seishiki na kōgi seimei o kōkan shita.
The governments of both countries exchanged formal protest statements through their embassies.
Tokyo hosts one of the densest concentrations of foreign embassies in the world. Minato Ward alone — covering neighborhoods such as Azabudai, Hiroo, and Moto-Azabu — is home to more than sixty embassies, including those of the United States, the United Kingdom, Germany, and France. This clustering is partly historical: when Japan reopened to the world in the Meiji era, the government designated Azabu as the preferred district for foreign legations, and the tradition continued into the postwar period. Walking through Hiroo today, you will see flags and discreet security barriers marking these diplomatic outposts between upscale supermarkets and quiet residential streets.
Understanding the distinction between taishikan (大使館, embassy) and ryōjikan (領事館, consulate) matters practically for anyone living or traveling in Japan. Japan maintains consulates in major regional cities such as Osaka, Sapporo, Fukuoka, and Nagoya, so foreign nationals outside Tokyo can access visa and passport services without traveling to the capital. Japanese news coverage frequently references taishikan in diplomatic contexts — summoning an ambassador (taishi o yobitsukeru) is a recognized signal of diplomatic displeasure, and the phrase appears regularly in international news segments on NHK.
