FEUDALISM AND ISOLATION
600s Once Japan unified in 600, the country was ruled by a samurai class during the Heian period (794-1603) and a feudal military dictatorship.
794 Under the Heian Period, the samurai class of Japanese warriors erodes the emperor’s control. The samurai’s influence and power grows and the local feudal system endures for 700 years.

1894-

    I didn’t think that there was enough exploration in to the feelings of the younger generation as to why all these constitutional restrictions exist.
    “How does it feel to be arming Japan in the shadow of Pearl Harbour and the Pacific War?”.
    “Does Japan have the right to arm itself?”
    Didn’t see those kinds of questions asked.
    On one had I would like to see the economic success provide leverage towards world peace, but after Hitler they inflicted the worst war crimes in modern military history.

    Your viewers might find my project website on Constitutional Revision in Japan a useful reference; you can find a Chronology, Bibliography, and links to 70 websites in Japan that debate this issue. Perhaps it would be a good link:http://www.fas.harvard.edu/~rijs/crrp/index.html. Feel free to use it!

    America’s encouragement of Japanese military build up is short sighted. Militarism is part of Japanese culture that does not go away in a generation or two. In the post-war years, that militaristic tendency was channeled into corporate expansion by the mini armies of Toyota and Honda. When that slowed down in the past decade, pressure started to build for a real military. More over, the opposition to war in Japan is invariably based on the self-pity brought by defeat, never was it based on a moral principle of humanity, not for the humanity outside Japan. As long as the Japanese youth are not taught about the true history of Japanese militarism, the rest of the world are not safe from it.

  • Liu Rui Qi

    Japanese militarization is only another step for America to channel it’s influence on Asia, as it needs to secure Asia. Otherwise, Asia’s many troubles will cause WWIII. Also, Japanese officials still pray at the Yakasuni shrine in Tokyo, the shrine where all of Japan’s soldiers are honored. Also, I cannot see why Japan needs a military. As long as it stays peaceful, no nation will attack it. Japanese aggressiveness should stay in technology.

  • nonnoboy

    Japan should have a full capable military, however it shouldn’t engage in wars. Nuclear submarines are needed to deter the PRC’s illegal actions into Japanese waters. Carriers are needed in case North Korea decides to aim their Taepo Dong II missiles over Tokyo (EVER AGAIN).

    Japan is a peaceful nation, however, the peaceful nations are surrounded by un-peaceful neighbours.

    America is known to trick other countries into doing their bidding. Philippines is a prime example during the Pacific war. They shouldn’t have armed and attack the Imperial Army, for it was a doomed and failed slaughter. Filipinos still resent that tactic today.

    America also pushed Iraq to arm and attack Iran. Not a very smart event, outside of securing oil with a the intent of having the muslims fight each other.

    America also is attempting to arm Japan and push them into bigger roles against China and even Iraq.

    This is where it stops. Japan’s Diet should have absolute right to declare war, no other body in parliament. And the SDF although should be ran freely to build up the MSDF and ASDF without restrictions, should not be allowed to engage in combat without the Diet.

    Call Japan’s Article 9 self-pity or moral principal of humanity, either way too many folks died. America, China, Korea are the countries that didn’t learn after the Pacific as they continued on with several more wars.

    Tora! Tora! Tora!
    Japan attacked Pearl Harbor! A Day of Infamy!

    Japan WW II atrocities in Asia was over-simplified in your time-line. They killed, raped, burnt and looted, detailed in the book, The Gold Warriors. They built their wealth by enslaving American POWs in the book, Unjust Enrichment. They invaded China in a reign of terror by “Loot All, Burn All and Kill All” policy with the infamous Rape of Nanking, Comfort Women (kidnaped girls into forced military sex slaves, germ/biological warfare (books: Unit 731, Death Factory and A Plague upon Humanity), Slave Labor (American POWs, Lester Tenney), Military Notes.

    Japan Prime Minister visit annually Tokyo Yakasuni Shrine where housed convicted Class A war criminals to revive past glory and resurrect militarism.

    Does Japan Diet apologize and compensate the Asian & Dutch victims officially and promise to teach their younger generations not to repeat aggression again as Germany did? Instead, they whitewash, distort and even deny their war crime against humanity. ( Please check VHS tape titled Murder Under the Sun, Japanese War Crimes and atrocities, Lou Reda Production).

    Your show documented why Japanese people led by monks oppose to change Article 9.

    This is why Japan was defeated in the bid for UN Security Council member lately !

    This is why SDF oversea deployment was closely watched!

    I have read all your comments and I think all of you have some legitimate point or another. But I would like for us to look at Japan from this perspective that people even nations make mistakes and I think they can learn from it. If anyone denies that point I would like to point to the mistakes of the previous generations of Americans of wiping out the natives, enslaving people of other races and wiping Heroshima and Nagasaki off the face of the map. I believe these were mistakes made by the previous generations of American that is still had for us to admit to in this generation of Americans. But has the USA been a force for good in recent times (specifically, after WWII)? I believe the answer is resoundingly YES. Though we uses some questionable means to achieve our ends of winning the cold-war. This is what I want any American to think about when looking back to the issue of Pearl Harbor, however painful the memories may be. I would also wish that other Asians will look at the big picture of the present stategic map of Asia.
    1) Japan is a democratic country
    2) China is a Communist country
    3) Japan has substansial technological, industrial, and manufacturing capital
    4) China has some but not as much as it wants.
    5) China has shown that it would like to become a superpower one day (a communist country)
    6) The USA is the only country providing Nuclear deterrance for its allies in Asia.
    7) If for any reason the USA is no longer able to properly propect its allies, specifically Japan, S.Korea and Taiwan. Those countries can be blackmailed into a stategic alliance by either China, Russia or N.Korea

    This would mean that their technological, industrial, manufacturing and monitary infrastructure will go to strenghtening a peer-competitor (Russia or China) which is not democratic and may be hostile to the USA, its other neighbors and the world.

    Also, I think that many Japaneese haven’t truely considered the geopolitical picture and realized that their country may be in a precarious position not only visa-ve N.Korea, but with the issue of China and Russia.
    Their country is also not a member of NATO, so the nuclear deterrence provided by the USA is not as strong as the one provided for Western Europe. Where there was a policy of Nuclear sharing (if a war occurs the USA will transfer Tactical weapons to NATO countires). Even still, the UK and France still opted to build their own minimal nuclear deterrance.

    What I am saying is this, the Japanese people can not wish these problems away and the idea that if Japan remains peaceful it will not have enemies does not stand up to the test of history. Sweden, Norway and Finland were neutral at the onset of WWII and Hitler still attacked and occupies them because of their industrial infrastructure.

    Japan and the other East Asian powers should not allow themselves to become a case study of what a wealthy, economically powerful country should not do.

    I personally believe that the Democratic countries in Asia should be armed to the teeth, not because of the shortterm problem that south korea pose, but the longer term problem posed by China, Russia and in a small degree N. Korea

    A minor error in the timeline – the Maritime Self-Defense Force did not sink the North Korean spy ship in 2001. The Japan Coast Guard did, which is part of a different agency/ministry and operates under different rules of engagement.
