The National Share Just Hit 99.2% — Kumamoto Day 11, and Why Japan Designated Two Disaster Statuses on the Same Day

This article follows our previous report covering day eight (updated August 5), organizing the situation as of day eleven of the earthquake, August 7. Please also see our earlier updates. Throughout this series, the designation had only ever been described as "expected." Eleven days in, it can finally be reported as done. On the same day, water outages fell into the 36,000-household range, and Kosa Town became the first affected municipality to fully resolve its outage.

What Changes With the Severe Disaster Designation?

Once a Severe Disaster designation is in place, the national subsidy rate for public infrastructure and farmland recovery projects rises, substantially easing the financial burden on affected municipalities. The government approved a cabinet order on August 7, by circular resolution, designating the Kumamoto earthquake a Severe Disaster (Cabinet Order No. 259), which was promulgated and took effect the same day. The Cabinet Office's disaster-designation status page has already been updated from "expected" to "designated (promulgated)."

The full-scale Severe Disaster designation carries four measures. First, special financial assistance for public infrastructure recovery projects raises the national subsidy rate, averaged over the past five fiscal years, from 71% to 84%. Adding local allocation tax adjustments that cover the remaining municipal share, the effective national burden rises from 98.6% to 99.2%. Farmland recovery projects follow the same pattern, rising from 86% to 97%, with an effective share of 98.0% to 99.6% once tax adjustments are included. Jointly used agriculture, forestry, and fishery facilities go from a normal 20% subsidy to 50%, or 90% in municipalities specifically designated by the agriculture ministry. Principal and interest payments on minor-disaster bonds become eligible for inclusion in the standard fiscal needs calculation.

One measure has not moved forward, however. A special credit-guarantee provision for small businesses — a narrower, localized designation that in this case would apply only to Mifune Town — remains at the "additional designation expected" stage as of August 7, and its underlying order has not been revised. That piece cannot yet be described as designated; the accurate description is that it remains pending.

The speed of the designation is worth noting. Prime Minister Takaichi had already said on August 3 that she expected public infrastructure and farmland recovery projects to receive the full Severe Disaster designation (TKU, Aug. 3). Kumamoto Governor Kei Kimura, that same day, had asked the national government for financial support on the scale of the 2016 Kumamoto earthquake and for an early designation. Counting from that request to the formal promulgation, the designation took just four days. NHK (filed 12:09 p.m., Aug. 7) also reported that "the government designated it a Severe Disaster at Friday's circular Cabinet meeting."

What Does the Specified Extreme Disaster Designation Mean for Daily Life?

A Specified Extreme Disaster designation is a mechanism that lets the national government, by cabinet order, uniformly extend legal deadlines when a major disaster makes it widely impossible for victims to meet obligations tied to their daily lives or businesses. On the same day as the Severe Disaster designation, August 7, the government also designated the Kumamoto earthquake a Specified Extreme Disaster (Cabinet Order No. 260), promulgated and enforced the same day.

This designation carries five measures, each with its own extended deadline. The expiration date for administrative rights and benefits — such as driver's licenses — is pushed to January 27, 2027 (Reiwa 9). Exemption from liability for failing to fulfill administrative obligations runs through November 27, 2026 (Reiwa 8). A special exception for corporate bankruptcy commencement decisions extends to July 27, 2028 (Reiwa 10). The period to accept or renounce an inheritance is extended to March 31, 2027 (Reiwa 9). And exemption from civil mediation filing fees runs through June 30, 2029 (Reiwa 11). Anyone who missed a license renewal, or who hasn't yet decided whether to renounce an inheritance, no longer has to worry about those deadlines slipping past.

A related cabinet order tied to Article 30 of the Comprehensive Legal Support Act was also approved the same day, August 7. However, its specific order number could not be confirmed as of that date, so the exact scope of any legal-consultation framework it enables cannot yet be stated with confidence. Phrases like "free legal consultations have begun" should not be used until confirmed by a primary source.

How Far Have Water Outages Fallen?

Water outages have fallen to about 36,400 households across three municipalities in Kumamoto Prefecture. Per the Ministry of Land, Infrastructure, Transport and Tourism's 33rd report (as of 1:00 p.m., Aug. 7; water figures as of 11:00 a.m.), that's down to roughly a third of the peak figure of about 108,100 households.

The biggest change is in Kosa Town. Its outage was fully resolved on August 7, ending a period of disruption that had run since July 28. That makes Kosa the first municipality hit by the earthquake to reach a complete resolution. Yatsushiro City — which this series had repeatedly described as barely moving since the quake — has also continued its gradual decline, down to about 23,462 households from a peak of 25,269. Uki City fell sharply to about 9,900 households, down from a peak of 18,000, and Hikawa Town stands at about 3,041. The Ministry's stance is unchanged: "working with full effort toward resolving outages by the end of August." 177 water trucks remain deployed — 18 from the Ministry, 102 from the Japan Water Works Association, and 57 from the Self-Defense Forces.

Fab restarts throughout this series have tracked closely with the recovery of tap water, the feedstock for ultrapure water (water purified to remove nearly all impurities). For more on how water access constrained fab restarts earlier in this series, see our rundown of every Kumamoto fab's status. Kosa Town's full resolution is small in absolute numbers, but it marks the first time this series has been able to report a municipality reaching zero — a milestone that hasn't appeared in any earlier update.

When Will Roads and Rail Come Back?

On roads, the Kyushu Expressway's Miyahara SA-Sakamoto PA section is now expected to open to emergency vehicles during the week of August 9. If that holds, emergency vehicles would be able to travel the entire length of the Kyushu Expressway. General-vehicle access is unchanged, still targeted for the latter half of August with some restrictions. On August 7, the Ministry began urging drivers to take a wide-area detour via the Higashi-Kyushu Expressway during the upcoming Obon holiday period, and started adjusting tolls to support that shift. The Yatsushiro JCT-Yatsushiro South IC section still has no timeline, though NEXCO West Japan held its first expert review committee meeting on August 6 to move repair planning forward.

On rail, the Hisatsu Orange Railway announced in an official statement dated August 7 that it would begin bus replacement service for the still-suspended Yatsushiro-Minamata section starting Monday, August 10, running six round trips a day on both weekdays and weekends. That gives residents a concrete interim option for a section of track that remains out of service. The Minamata-Sendai section, by contrast, already resumed running on August 5.

At Yatsushiro Port, every public berth sustained damage, and assessments of which ones can reopen are proceeding section by section. The container crane remains out of service, with rail deformation and an oil leak still under review for repair. On temporary housing, rental-type units are accepting applications in 12 municipalities, while construction-type units have already broken ground — 50 in Uki City and 20 in Hikawa Town.

What Is the State of Recovery at the Factories?

The gap in recovery pace between automakers and chipmakers has grown even clearer. In an official update on August 7, Honda confirmed that its Kumamoto plant, which builds motorcycles, is entering its previously scheduled summer holiday from August 8 through 16. Beyond that, the company said it would keep completed-vehicle production halted past August 17, resuming operations progressively, process by process, as each clears recovery milestones. Nothing has changed at its Saitama plant (Aug. 5-19), Suzuka plant (Aug. 6-19), or Honda Auto Body (Aug. 6-19). The fact that the motorcycle plant's halt now extends beyond August 17 makes it the longest automotive shutdown timeline this series has reported.

Semiconductor makers, meanwhile, have issued no new official statements as of August 7. Sony's second statement (July 31) and Renesas's fourth statement (August 4) remain the latest — confirmed by checking each company's official page directly, with no updates as of the evening of August 7. That silence can be read as a sign the recovery phase for chipmakers has already entered its late stage, with fewer new developments requiring a fresh update. Why semiconductors and automaking have diverged so much in recovery speed comes back to a point this series raised early on: some products made in Kumamoto have backup factories elsewhere, and some don't. See our earlier analysis of which Kumamoto-made products can be built elsewhere — and which can't for more on that structural difference. Auto parts supply chains, once broken, also tend to take longer to rebuild than a single fab's own equipment does.

As for Toyota's three Fukuoka plants, they are reported to have resumed on August 6, consistent with the August 5 media report — but as of August 7, no report has surfaced confirming that the restart actually happened that day. The accurate statement for now remains: "reported to have resumed August 6 (media-sourced)." Reports on Daihatsu Kyushu remain inconsistent across outlets, so this update does not include them.

What Risks Lie Ahead?

The next concern is Typhoon No. 13. The Ministry's 33rd report (as of 11:30 a.m., Aug. 7) expects it to "maintain strong intensity while approaching Okinawa and Amami from the 7th through the 8th, then move through the East China Sea through the 10th." As for direct impact on Kumamoto Prefecture, the report notes "possible strong winds around the 9th as pressure gradients steepen under the typhoon's influence."

On the ground, media reports (Weathernews, Aug. 7) show the typhoon making its closest approach to Okinawa's main island on August 7, with winds of 34.5 m/s recorded on Amami Oshima and a gust of 41.2 m/s at Tokunoshima Airport. Kumamoto Prefecture falls within the storm's wind field, but no major impact is currently expected (Nishinippon Shimbun, tenki.jp). The prefecture continues to see intense heat, with highs holding around 35°C.

Damage surveys are also still progressing. The Fire and Disaster Management Agency's 45th report (as of 1:00 p.m., Aug. 7) puts the death toll at 38, unchanged from the 42nd report, while injuries rose to 159 (22 serious, 137 minor or other), up 12 from 147. Damaged homes now total 8,607 (699 totally destroyed, 1,045 half-destroyed, 6,863 partially damaged), with the entire 660-home increase from the 42nd report falling under the partially-damaged category. The evacuation-order population remains at 3 cities and 2 towns, 108,307 households, and 228,736 people. Media-reported evacuee figures (NHK and Kumamoto Prefecture's disaster response headquarters, as of 2:00 p.m., Aug. 7) put shelters at 125 locations with 6,651 evacuees.

At the 8th disaster-response headquarters meeting, held at the Prime Minister's Office on August 7, the Prime Minister instructed officials to accelerate the water-outage response — including emergency water-pipe installation — provide hands-on support for temporary housing alongside prompt secondary evacuation and move-in, add 700 security cameras to the existing 250, and procure and deploy tarps ahead of Typhoon No. 13. On water outages specifically, she called for "thorough process management to fully resolve water outages by the end of August." Together with the cabinet orders formally designating the earthquake a Severe Disaster and a Specified Extreme Disaster, the government has now entered a phase of pursuing infrastructure recovery and livelihood rebuilding side by side.

Key Takeaways

• The government approved cabinet orders by circular resolution on August 7 designating the Kumamoto earthquake a Severe Disaster (Cabinet Order No. 259) and a Specified Extreme Disaster (Cabinet Order No. 260), both promulgated and enforced the same day. The effective national share of public infrastructure repair costs rises to 99.2%, and farmland to 99.6%. The formal designation came just four days after Governor Kimura's request on August 3.
• Under the Specified Extreme Disaster designation, deadlines for administrative rights and benefits like driver's licenses are extended to January 27, 2027, and the window to accept or renounce an inheritance to March 31, 2027. A separate small-business credit-guarantee measure for Mifune Town remains at the "expected" stage.
• Water outages fell to about 36,400 households across three municipalities in Kumamoto Prefecture, and Kosa Town became the first affected municipality to fully resolve its outage, on August 7. The Hisatsu Orange Railway will begin bus replacement service for the Yatsushiro-Minamata section starting August 10.
• Honda said its Kumamoto motorcycle plant will keep completed-vehicle production halted past August 17 — the longest automotive shutdown timeline reported in this series. Semiconductor makers have issued no new statements as of August 7, suggesting their recovery phase has entered its late stage.
• The Fire Agency's 45th report put damaged homes at 8,607, but the entire increase reflects reclassification into the partially-damaged category. Typhoon No. 13 brought violent winds to the Amami region, though its impact on Kumamoto Prefecture is expected to be limited.
