The “Yanai Report” on Article 9, Part 4

The next segment of my analysis of the Yanai Report is long overdue. The final two posts were supposed to be the critical analysis of the report, from both a constitutional and international law perspective. The constitutional criticism was briefly explained in my Op-Ed piece in the Japan Times, which can be found here. Before posting a more developed version of that, together with the international law critique, I am posting below the Japanese translation of the Op-Ed piece. It was declined by the Asahi Shinbun (ostensibly because it was too narrow in focussing exclusively on one fundamental flaw in the report), but I thought that it should be made available somewhere for wider consumption, since there has been little debate on this aspect of the report in the Japanese media. The eloquent translation is thanks to Prof. Norimoto Setsuko.




当時の福田康夫首相は、この報告書すなわち憲法の「再解釈」にはほとんど興味を示さなかった。しかし麻生首相は、第9条は「再解釈」されなければならないと、国連で繰り返し述べた。さらに柳井報告書が、官僚たちの間で歓迎され、政府内において次第に影響力を行使しそうな証拠がある。したがってこの報告書は、もっと公に吟味の対象とならなければならないのである。Read more…

The “Yanai Report” on Art. 9, Part 3

Continuing from the last post, this posting examines Part III of the Yanai Report, which is the heart of the argument on the actual interpretation of Art. 9. While the earlier posts were summaries combined with some select segments being translated almost in full, this posting is less a summary and more a full report on the substance of this part of the report. There is much to criticize here, but the analysis is left for the fourth and final posting on the report.

Part III, Section 1 – Opinions and Their Premises Regarding the 4 Scenarios: the panel returns to the question of constitutional interpretation, this time explaining “The Panel’s Fundamental Understanding of Art. 9.” In section one of this part, the panel outlines its opinion and its underlying assumptions with respect to the four problems. After rehashing the changes in threats already discussed above, it articulates the two assumptions that underlie its recommendations for the minimum necessary changes to the interpretation of the Constitution. These are i) that there must be continued maintenance of pacifism and international cooperation as fundamental principles of the Constitution; and ii) even where there is the exercise of collective self-defence or collective security operations under a new national security policy, it cannot be without limits. The panel indicates that the specific limitations will be discussed in Part IV.

Part III, Section 2 – The Interpretation of Art. 9: The panel turns next to its own interpretation of Art. 9. It again summarizes the government interpretation, then begins its discussion with the assertion that in interpreting laws and the Constitution, while it may be natural to interpret the text of each provision, it is also necessary to examine the entire context of the law in its entirety, the history of its formation, the country’s national strategies, the society as a whole, the economy, and other related circumstances.

The “Yanai Report” on Art. 9, Part 2.

Continuing from the last posting, this segment reviews the substance of Part I and Part II of the report, with particular emphasis on Part I. It will be recalled that Part I was entitled “The National Security Environment of Japan and the Need for a Reconstruction of the Legal Foundation”.

Part I, section 1

It begins by establishing the premise that it is necessary for the national security policy of Japan to adapt to changes in the international environment. Moving from that premise, the report then establishes that as a country governed by the rule of law, the national security policy must be constructed on a foundation of clearly defined laws. However, it argues that this foundation must constantly be re-examined so as to accord with the reality of shifts in the national security threats. It asserts that while the legal foundation as it now exists is based in part on the Constitution, it also reflects the historical reality, both in political and in strategic terms, that existed at the time of its formation. Since those circumstances have changed, it is appropriate to re-examine and reform the legal foundation to ensure it complies with today’s realities.

This conclusion is followed by several qualifiers, regarding the degree of change in the threat environment that makes such reform necessary, and the assertion that “it goes without saying that the interpretation of law cannot simply be a convenience to be adjusted in conformity with the circumstances. But nor does it mean that looked at legally, the interpretation that has been maintained until now is the only possible rational interpretation.” It then goes on to criticize the government interpretation of Art. 9 as being excessively complicated and inconsistent with international law.Read more…

Japan Opens Up Way For Military Use of Outer Space

(Written for and appearing in Foreign Policy Digest)


Japan’s Diet (legislature) passed a new Basic Law on Space on May 21 (the bill can be found in the index on-line here, and in pdf here ), which will permit Japan for the first time to use space for the purposes of contributing to national security. This constituted a marked departure from an almost 40 year old policy of strict non-military use of outer space.

While the passing of the law received some passing coverage in the Western press , the significance of this development remains largely unexplored. The move is important in two respects – the first being its place in a systematic widening of the scope of Japanese military activity notwithstanding constitutional constraints, and the second is the extent to which it may contribute to an escalation in the militarization of space among East Asian countries. This article focuses on the first aspect.


To put all of this into context one has to begin with the Japanese constitutional constraints on the use of force and maintenance of armaments. Article 9 of the 1947 Constitution provides that Japan forever renounces war and the threat or use of armed force for the purposes of settling international disputes. It also, in Art. 9(2), declares that it shall never maintain land, sea, or air forces or any other war potential, and that the rights of belligerency will not be recognized. … Read more…
