“Tokyo is the de jure capital of Japan.”

Article 1 states: “The capital city construction project means the project for the construction of the capital city Tokyo.” The law explicitly uses the term “capital city Tokyo,” making it a primary legal source relevant to claims about Tokyo’s legal capital status. This law was later repealed, so it is important as historical legal evidence but not necessarily current law.

This law defines the “capital region” as “the areas within Tokyo Metropolis and the adjoining areas.” It is relevant because it shows the current statutory framework centers on Tokyo as the capital region’s core, though it does not explicitly state that Tokyo is the capital city. It is background evidence for Tokyo’s legal-centrality rather than a direct declaration of de jure capital status.

“What is the capital of Japan? And where is it decided? In fact, there is currently no law that defines the capital.” The column then quotes a 1979 statement by the Director-General of the Cabinet Legislation Bureau: “However, ‘the conviction that Tokyo is the capital of Japan is something that, I believe, no Japanese citizen would doubt.’” The article explains that while there are legal provisions for the “capital region (首都圏)”, there is no statute that stipulates which city is the “capital (首都)” itself.

The Diet member’s question begins: “Although Japan’s capital is understood by most citizens to be Tokyo Metropolis, at present I consider that there is no legal basis for this.” It notes that the former Capital Construction Act (首都建設法) Article 1 stated, “The purpose of this Act is to plan and construct Tokyo Metropolis as the new capital of our peaceful state…”, but that this law was abolished in 1956. The question further states: “Although Article 2 of the Capital Region Development Act defines the ‘capital region’ as ‘the area consisting of Tokyo Metropolis and its surrounding areas specified by Cabinet Order’, it does not explicitly indicate where the capital of Japan is.”

The ministry’s capital-region materials discuss Tokyo as the core of Japan’s capital region and describe legal frameworks for the “capital region” surrounding Tokyo. These official policy pages support Tokyo’s central governmental role, but they do not provide a current, explicit statutory sentence declaring Tokyo the capital city.

Article 2 of the Capital Region Development Act defines the ‘capital region (首都圏)’ as follows: “In this Act, ‘capital region’ means the wide area consisting of the area of Tokyo Metropolis and the surrounding areas specified by Cabinet Order.” The Act does not contain any article that directly defines which city is the ‘capital (首都)’ of Japan; it only defines the ‘capital region’ using Tokyo as its core.

This act establishes the “Capital Zone” and defines it geographically around Tokyo and adjacent prefectures. It does not contain a simple clause saying “Tokyo is the capital,” so it is relevant background to the legal-status argument but not direct proof of the claim.

The capital is Tokyo. The Factbook lists Tokyo as Japan’s capital in its country profile.

Cabinet Office materials describe Tokyo as the center of national administration and discuss the capital region around Tokyo. These official government materials are relevant background for Tokyo’s political status, but they do not on their face provide a present-day statutory declaration that Tokyo is the de jure capital.

In the section “1-1. Definition of ‘capital’ in domestic law”, the Osaka Prefectural Government document states: “There is no law in our country that directly defines ‘the capital’ (首都). Note that in the Capital Construction Act, which existed from 1950 to 1956, it was stipulated that ‘the purpose is to construct Tokyo Metropolis as the capital…’.” It adds: “There are laws that allow one to infer that the capital is Tokyo, such as those defining Tokyo as the ‘capital region (首都圏)’.”

Article 1 of the (now repealed) Capital Construction Act stated: “The purpose of this Act is to plan and construct Tokyo Metropolis so that it may fully perform its functions in politics, economy, culture, etc., as the new capital of our peaceful state.” This law, which explicitly treated Tokyo Metropolis “as the capital”, was later repealed and is no longer in force.

Although practically everyone refers to Tokyo as Japan's capital, there is actually no law that designates it as such. The postwar Constitution and related statutes place the Diet, the Cabinet Office and other central government organs in Tokyo, and diplomatic practice treats Tokyo as the capital. But some scholars and Kyoto residents argue that because there has never been a formal legal transfer of the capital from Kyoto by using the term ‘sento,’ Tokyo is only the de facto capital, not the de jure one.

Tokyo is the capital of Japan and one of the world’s largest cities. Besides being the political center of Japan, Tokyo is also the financial, cultural, and industrial center of Japan and a major international financial center.

Tokyo is Japan’s capital and largest city. It is the country’s political, economic and cultural center.

Tokyo is the capital city of Japan, a title the city has held since 1868 after it was renamed from Edo. While Tokyo is considered the capital city of Japan, there exists no law in the country which explicitly gives Tokyo that distinction. Therefore, Tokyo is considered the de facto capital and not de jure capital of Japan.

Japan’s legal history is often discussed in relation to the 1950 Capital City Construction Law, which explicitly named Tokyo the capital city, but that law was later repealed in 1956 and replaced by capital-region legislation. Because the repealed law is not current law, it is relevant historical context but weak support for a claim that Tokyo is the current de jure capital.

The article explains: “In fact, there is currently no law that directly stipulates the content ‘Japan’s capital is Tokyo’.” It continues: “Therefore, for example, even if a law were enacted that ‘makes Nagoya the capital of Japan’, there would be no contradiction.” Later it concludes: “In other words, Tokyo Metropolis is a ‘de facto capital’ that is not determined as the capital under law.”

Discussing Japan, the article says: “We earlier stated that one can say Japan has no capital, but I think many people recognize Tokyo as the capital. So why can it be said there is no capital? The reason is that there are no provisions in the constitution or in any law that stipulate Tokyo as the capital.” It then cites the 2018 government reply: “The government’s answer here is, ‘Although there is no law that directly stipulates that the capital is Tokyo Metropolis, we consider that Tokyo Metropolis being the capital of Japan is widely accepted by the general public.’ Therefore, it may be said that in practice the capital is Tokyo.”

The video argues that Japan never issued a formal decree transferring the capital from Kyoto to Tokyo, and that the 1950 Capital City Construction Law was later repealed. It presents the position that Tokyo is not officially the capital, but it is a secondary commentary source rather than a primary legal record.
