Japan government weighs second supplementary budget focused on disaster response
In short
The Japanese government is considering a second supplementary budget for fiscal 2026, limited to necessary items such as disaster response rather than an economic-stimulus package, with spending expected to be small. It would cover recovery from July's Kumamoto earthquake and August's heavy rain in Chiba, civil servant pay increases, and public works timing, with drafting possibly starting in November and enactment sought in the ordinary Diet session early next year.

The Japanese government has entered deliberations on compiling a second supplementary budget for fiscal 2026, according to multiple government officials cited in reports. Unlike the economic-stimulus supplementary budgets of recent years, the budget would be limited to necessary items including disaster response, and spending is expected to be small, Yomiuri Shimbun, Nippon TV News and Mainichi Shimbun reported. [ 1 , 2 , 7 , 9 ]
According to the reports, the budget would fund recovery and reconstruction after the Kumamoto earthquake in July and heavy rain in Chiba in August, and would prepare for a shortfall in reserve funds as disaster-related spending continues, Sankei Shimbun reported. It would also cover increases in civil servant personnel costs following the August National Personnel Authority recommendation, and costs to spread out the timing of public works projects, Nikkei, Nippon TV News and others reported. Asahi Shimbun reported it would also address improved treatment for childcare workers. [ 3 , 5 , 7 , 8 , 9 ]
On timing, Yomiuri and Mainichi reported drafting work could begin as early as November, with enactment sought in the ordinary Diet session at the start of the year. Nikkei said the budget would be assembled toward the end of the year and submitted to the ordinary Diet in 2027. [ 1 , 3 , 9 ]
The Takaichi administration has said it will consolidate foreseeable expenses into the initial budget and move away from reliance on supplementary budgets. Government officials said the second supplementary budget does not contradict that policy because it is limited to highly necessary projects, according to Yomiuri and Nippon TV News. [ 1 , 7 ]
The government enacted a first supplementary budget for fiscal 2026 in June totaling about 3.1135 trillion yen, mainly for gasoline subsidies and household support amid the Middle East situation, Yomiuri, Sankei and Mainichi reported. The fiscal 2025 supplementary budget reached about 18.3 trillion yen, according to Yomiuri and Sankei. Asahi noted that large autumn supplementary budgets have become common and that loose fiscal discipline has been questioned. Yomiuri reported that the construction industry had worried that consolidating budget measures into the initial budget would further reduce work in April to June, a slack period. [ 1 , 5 , 8 , 9 ]
Why it matters
The budget would shape how Japan funds disaster recovery and public works in the current fiscal year without returning to the large annual stimulus budgets the government says it wants to end. Because it is described as limited in scale, the main effect is expected to be on specific spending items named in the documents — disaster reconstruction, civil servant pay and public works scheduling — rather than on the wider economy.
