JAPAN AS FRONTLINE STATE FOR UNITED STATES IN WESTERN PACIFIC SECURITY ARCHITECTURE-2022 REVIEW

Japan's National Security threat perceptions in 2022 are overwhelmingly dominated by the China Threat which has emerged as an unprecedented menacing and predatory threat posed by Communist China to Indo Pacific security surpassing in potency the Soviet Threat that hovered during Cold War 1.0.

Japan's natural choice to ensure its national survival against the Soviet Threat earlier and now the more aggressive China Threat lay with the United States. This was achieved through the US-Japan Mutual Security Treaty which also facilitated US Military Forces to be positioned in Japan as US Forward Military Presence numbering over 40,000.

The United States despite having imposed a Peace Constitution on Japan after World War II limiting Japan's security to Self Defense Forces, soon realized, that not only security of the Japanese Mainland but also the overall security of  Continental USA rested on Japan as the pivotal component of US-configured security architecture in the Western Pacific, earlier against the Soviet Threat and in the 21st Century against the much more potent China Threat.

During Cold War 1.0 against the Soviet Threat, the Japanese Self Defense Forces were incrementally made to share the security of sea-lanes of communication (SLOCs) extending to 1,000 nautical miles from Japan across the South China Sea expanse. Denial of Japanese Straits for Soviet submarines to breakout into the Pacific was also a major task.

The enormity of the China Threat to Western Pacific security, Japan's security per se, and to Continental USA that has unfolded in the first decade of the 21st Century has prompted the United States to shed its earlier misgivings about re-emergence of Japanese militarism (fostered by China and lapped up by US), has now given way to the United States even encouraging Japan to acquire offensive and Force Projection capabilities for Japanese Armed Forces.

Japan today is engaged in a sustained drive in the above direction. Reports also indicate of the conversion of the two Helicopter Carriers of Japanese Navy into mini- Aircraft Carriers to operate F-35s. Missile ranges are also being doubled.

Japan is actively participating in joint patrolling of the South China Sea and capacity-building of Navies of Vietnam and the Philippines besides investing in the security of other South East Asian countries perceiving the China Threat.

Japan is an active member of QUAD and has forged substantive defence relationships with India and Australia--all supplementing the overall effort of securing the Indo Pacific against Chinese expansionism.

Concluding, all that one can emphasize is that Japan in face of the China Threat menacing the security of Indo Pacific Region has emerged even more distinctively as the most pivotal component of the US-configured security architecture not only for the Western Pacific but even for the overall  Indo Pacific Security architecture to checkmate the China Threat. Japan today is involved in that direction with United States, India and Australia---with European Nations also pitching in now.
