Former Japanese Prime Minister Yasuo Fukuda has died at age 90, a loss for Japan's political establishment and for Taiwan-Japan relations, which he worked to strengthen.

• Fukuda served as Japan's 91st prime minister and held cabinet posts under earlier PMs before leading the government himself.
• As prime minister he pushed global warming policy, and after leaving politics he kept working to improve Japan's relations with China.
• Taiwan's President William Lai publicly mourned his death and sent condolences to his family and to Japan, calling the Taiwan-Japan relationship deep and expressing hope that cooperation between the two continues.

Outlook: No major policy shift is expected, but tributes from regional leaders are likely to continue in the coming days.
