What happened to Japan in the Cyberpunk universe (2020–2077)?

In Cyberpunk lore, Japan (Empire of Japan (Arasaka Zaibatsu Corporate Hegemony)) is aligned with Arasaka Corporation, Kendachi, Tsunami Defense & Zetatech. In 2020 (● FOURTH CORP WAR ARASAKA CITADEL, Sovereignty 20%): During the Fourth Corporate War (2021–2023), Saburo’s eldest son Kei Arasaka wages unrestricted global war against Militech, deploying Arasaka armies and Soulkiller netrunners. By 2077 (● IMMORTAL ZAIBATSU EMPIRE, Sovereignty 0%): At 158 years old, Saburo Arasaka rules a reunited, deadlier Arasaka Empire until his murder by his son Yorinobu in Night City—only for Saburo’s engram to overwrite Yorinobu’s body via the Relic.
