31.03.2026 ⇢ The Day the Nikkei Plunged 7,786 Yen
⌹

Japanese editors prioritized the Nikkei 225's record 7,786-yen monthly plunge, the largest in 35 years, attributed to Middle East turmoil.

This economic crisis coincided with a governance collapse at KDDI, where 246 billion yen in fictitious sales led to executive resignations.

In response to the energy crisis, Prime Minister Takaichi formalized a ministerial task force to secure petroleum and medical supplies.

Simultaneously, the first domestic deployment of long-range counterstrike missiles in Kumamoto marked a concrete shift in Japan's defensive posture.
