Public finance is the backbone of the country. If it collapses, the country collapses. It is therefore necessary to clearly indicate numerical targets for fiscal reconstruction in the Constitution, which shapes the country. The same can be said for the Dō system. Taking the revision of the Constitution as an opportunity, the people of Japan should have a thorough debate and carry out a revolution to reshape the country. It is also necessary to introduce a constitutional court, which currently does not exist in Japan, on the occasion of the revision of the Constitution.

The problems associated with the current Japanese bicameral system can be roughly grouped into: 1) the risk of a divided parliament, 2) the electoral system, and 3) the homogeneity of arguments between the two Houses of the Diet. The optimal solutions identified based on precedents in other countries are: 1) differentiation of the authorities of the two Houses (elevate the authority of the House of Representatives to a superior level), 2) differentiation of the methods of electing members of the two Houses, and 3) differentiation of the roles of the two Houses. These measures will reshape the Diet in a positive direction. The revision of the Constitution can be considered the best opportunity for fundamental reform of the Diet and the political system.

It is sometimes said that the Constitution of Japan is like the pocket of Doraemon. This refers to Article 13, which stipulates the “right to the pursuit of happiness.” This is the article based on which many new human rights to be guaranteed have emerged in response to changes in our society. These new human rights should be included in the new Constitution. At the same time, it is necessary for us to consider how to define the “responsibility of the Japanese people” and the “roles of Japan and its people” in order for the Japanese people, as the sovereign, to be involved in the national administration and for the creation of the best possible Japan.

According to Yukio Okamoto, a former diplomat, “We Japanese people should be proud of the path we have followed as a world-acclaimed peaceful nation under Article 9 of the Constitution. However, the reason why we have managed to get by without being attacked by other countries despite our low level of defense spending is not because of Article 9 but because of the defense system under the Japan-U.S. Security Treaty.” There is no guarantee that this deterrent system can be maintained into the future. It is necessary to develop realistic security policies that take into account the environment we are in.

What is a constitution? From a modern constitutional perspective, which was established through people’s revolutions in Europe, the purpose of a constitution is to “limit the national authority to protect human rights.” In the present day, however, a constitution should both serve as the limiting legislation for a state while at the same time providing the grand design of the state and describing the basic values of the country and society. In the new Constitution, it is necessary to clearly present this basic concept at the beginning.

The Constitution of Japan is the oldest in the world. More precisely, among modern constitutions it is the 14th oldest, but all of the constitutions enacted before the Constitution of Japan have been frequently amended. For this reason, it is not wrong to say that the Constitution of Japan is the oldest in the world. We, as the sovereign, must take a serious look at the Constitution, which defines the rights of the Japanese people and the basic structure of Japan. We are entering an era where we must exit the mode of “ceasing to think” and start creating a Constitution that reflects the times.
