Tokyo investors on August 19 focused on post-close corporate disclosures led by Oi Electric, whose shares rose after it completed a 173,800-share repurchase for ¥860.31 million, equivalent to 13.08% of outstanding shares. Watts shares reached a year-to-date high after the 100-yen shop operator raised its fiscal year ending August 2026 net profit forecast from ¥900 million to ¥1 billion and its year-end dividend forecast from ¥12.50 to ¥15.50 per share, mainly because of one-time gains linked to selling its Peruvian subsidiary. Other themes included Oxide's laser milestone, additional buybacks, Kaneka's ¥3.63 billion damages suit against Onamba, and Resorttrust's overseas medical-services alliance with Mitsubishi Corporation.
