Segments of the Chinese Nationalist and of the Japan underground government are attempting to implement plans to provoke a third World War.
This is being done in the name of Greater Asian-ism with the purpose of fostering an asiatic race liberation movement and reviving the influence of the Chinese Nationalist Government. OKAWA Shumei reportedly emphasized the fact that only through a third world War can complete independence of Asia be realized.
...These four men are reported to be planning in secret the reconstruction of the Japanese military. "Their initial aim is the organization of a volunteer corps to join the Chinese Nationalists in their defense of Formosa and then to gradually increase the size and equipment of the group until it becomes a power for those whose service both the East and West will bid prior to the inevitable World War III."
...In the event of war between the US and the USSR, ultra-rightists OKAWA Shumei, ISHIHARA Kanji and KITA Ikki groups will aid the Soviets.

I'm not very knowledgeable about the other authors, but Kita Ikki was a staunch anti-capitalist and a proponent of left-right syncretism in Imperial Japan.

The Japanese far right (historically) has been strongly pan-asianist as the primary theoretical component of its historical imperialist ideology.
The modern Japanese right's ideology is the distinct from Imperial Japanese ideology as the former is predicated on neoconservative, liberal democratic geopolitics combating communism serving American influence, while the latter was explicitly antagonistic to pro western ideology.
For a comparison, the left wing Strasser brothers of the German National Socialists also were firmly antagonistic to anglo American liberalism/capitalism, preferring to ally with the Soviet Union, but their faction would be purged in the Night of Long Knives by the SS.
Interestingly, Kita's anti capitalist faction was also purged in 1936/7, with the intention of appeasing the conservative samurai, just as the Strassers' anti capitalist faction was purged to appease the conservative junkers.
