What we know so far
About the 2026 Kumamoto Earthquake
- On July 28, 2026, an earthquake registering a maximum of 7 on Japan's seismic intensity scale struck Kumamoto Prefecture. The Japan Meteorological Agency officially named it the "2026 Kumamoto Earthquake."
- The Disaster Relief Act was applied to 10 cities, 10 towns, and one village in Kumamoto Prefecture (effective July 28).
- These include Yatsushiro City and Hikawa Town.
- Yatsushiro City recorded an intensity of 6-upper, and an evacuation order was issued for the entire city.
- News reports have confirmed damage inside the Honmachi shopping arcade in central Yatsushiro.
Yatsushiro City and Hikawa Town: where things stand (as of September 21)
- 13 evacuation centers remain open in Yatsushiro City, sheltering 782 people (as of 6:00, September 21).
- 2 of those centers are in Kagami and Sencho, sheltering 88 people — roughly one in 9 of everyone still evacuated in the city.
- Water in Kagami and Sencho is supplied by the Yatsushiro Living Environment Office Association. Service was restored in Sencho on August 25 and in Kagami on August 26, and the water is safe to drink. If no water comes out at home, check whether the main valve inside the meter box is open. Water may run cloudy right after service resumes — let it run until it clears. Even in restored areas, supply may be cut again for nearby leak repairs.
- In Hikawa Town, service was restored on August 27 in the Yoshimoto, Takatsuka, Shinden and Nozu areas — in each case for part of the area, not all of it. Part of the Ono area has also been restored. Areas without water remain, and the association is continuing test flows and leak repairs.
The full extent of the damage is still being assessed. Where figures are not yet confirmed, we will not speculate on this page. Updates will be posted in the Updates section below.

Why Sustainable Map is raising this fund
First, something we want to say upfront.
The Japanese Red Cross Society, Kumamoto Prefecture, and Yatsushiro City are already accepting official disaster donations.
You can also support the recovery through hometown tax donations (furusato nozei) to Yatsushiro City.
If you want a tax-deductible donation delivered through official channels, those are the best options.
Links are provided further down this page.
That said, here is why we are standing up.
Sustainable Map is a nonprofit based in Asao Ward, Kawasaki, Japan, that creates opportunities for children to engage directly with their community and society.
What we have always said is: "Think Glocally, Act Locally."
Small local actions, accumulated, are what move the bigger picture.
If we don't live by those words when a place we are personally connected to is shaken, they are just a slogan.
A relief fund, not a distribution fund
In Japan, disaster giving takes two forms.
Gienkin is money distributed directly to affected households through official distribution committees.
Shienkin (a relief fund) is money used for the relief activities themselves.
What we are collecting is the latter.
The reason: we want to judge what is missing right now — based on information from the ground and from disaster-relief professionals — and deliver support to the right place at the right time.
Right now, speed matters more than anything.
Gienkin passes through a distribution committee, so it can take months to reach affected households. Yatsushiro City states that the timing and amount of distribution are still undecided.
That process exists to guarantee fairness, and it matters — but it cannot meet what is missing on the ground today.
So we are not waiting until donations close.
As soon as a recipient is confirmed, we send funds. We don't collect first and act later — we act while we collect.
Where the money goes
- Funds will go to an NPO supporting children, and to disaster-relief organizations working on the front lines. We plan to donate to an organization running a safe space for children affected by the disaster in Yatsushiro City, and to organizations in Hikawa Town working on damaged houses, running evacuation shelters, and coordinating food supplies. Each organization's name will be posted on this page, together with the amount and date, at the time of the donation.
- Which organizations receive how much will be decided by needs on the ground. We hear directly — through the network of organizations working on-site and from disaster-relief professionals — what is missing right now, and deliver support where and when it is needed.
- We will also go to the affected area and provide direct support ourselves. The costs of that work will also come from this fund: purchasing supplies, equipment, on-site expenses, and transportation to the area.
- Everything — donations to organizations and our own direct spending — will be recorded on this page with amounts and dates.
Our promises
How this fund is handled
- Donation period: August 5 – October 31, 2026
- No fundraising target. Whatever is raised will be delivered, reliably.
- Incidental costs — transfer and payment-processing fees — are capped at 5% of the total fund. This includes the credit card processor's fee. Anything above 5% is covered by our organization, not deducted from the fund. The actual amount is published in Fund Status.
- The fund is used for two things: donations to relief organizations, and direct support on the ground. Direct support covers purchasing supplies, equipment, on-site expenses, and transportation to the area.
- Any funds remaining when the period ends will not stay with us. The full remainder will be donated to disaster-relief organizations active on the ground at that time.
- The Fund Status section is updated daily for the time being. On days with no movement, we will say so. Once the situation settles, we will switch to weekly updates (Fridays), and to monthly updates after the donation period ends. Any change will be announced in Updates first.
How to donate
Our bank account cannot receive transfers from outside Japan, so credit card is the way to donate from overseas.
Please pay in Japanese yen (JPY) — this avoids an additional currency-conversion fee.
The card processor deducts a payment-processing fee of 3.6%. A card donation is received net of that fee.
We ourselves deduct nothing from what the fund receives.
Donations to this fund are not tax-deductible in Japan.
Sustainable Map is a general incorporated association — not a certified NPO or a public interest corporation — so we cannot offer preferential tax treatment for donations.
If you want a tax-deductible way to help, please use the official channels below. (You do not need to go through us. What matters most is that help arrives.)
- Kumamoto Prefecture — official donations (in Japanese; July 29 – October 30, 2026)
- Japanese Red Cross Society — 2026 Kumamoto Earthquake donations (in Japanese; July 31 – October 30, 2026)
- Yatsushiro City — official donations (in Japanese)
- Yatsushiro City — hometown tax donations (furusato nozei) (in Japanese)
If you need a receipt, please contact us using the form at the bottom of this page. We will issue one individually.

Donations received have passed ¥500,000.
Thank you to the 35 people who have supported us so far.

We donated five mid-size drones to Yamazaru Co., Ltd.
This did not come out of the donations entrusted to us. They were provided by Glocal Act Co., Ltd., an affiliated company of ours. The figures under “Fund status” on this page are therefore unchanged. We are not disclosing the cost.
Yamazaru continues to tarp the roofs of damaged houses in Matsubase and Shiranui, Uki City, free of charge. In a post on August 19, the company described working on steeply pitched roofs where “there was a risk of secondary harm from aftershocks.”
We handed the drones over because we believed they were needed for roof repair work.
Yamazaru Co., Ltd. (in Japanese) -
August 27, 2026
We sent ¥50,000 to Yamazaru Co., Ltd.
Yamazaru is a landscaping and specialist tree-felling company based in Kumamoto City. Since July 28, the day of the earthquake, it has been working in Matsubase and Shiranui in Uki City — tarping damaged roofs, removing collapsed block walls and stone walls, clearing debris, carrying out household belongings, and making temporary repairs to household water pipes.
All of it is free of charge. The company does not charge for tarpaulins or sandbags either, and writes that this is made possible by support from people across the country. It gives priority to older residents, people with disabilities, and single-parent households, and puts up notices in community halls — with the local district head’s permission — so that people who do not use social media can reach them too.
A tarpaulin on a damaged roof only helps if it is up before the next rain. We are entrusting what we hold to people who take on that urgent part without charging for it.
The ¥100 bank transfer fee for this remittance is recorded under administrative costs. These now total ¥929 (0.20% of donations received).

August 27, 2026
We sent ¥50,000 to Disaster NGO Yui.
Yui sent an advance team the night the earthquake struck on July 28, and announced its Kumamoto response on August 3. Uki City and Hikawa Town recorded shindo 7; Yatsushiro City, shindo 6+. To reach all three, Yui set up a base that NPOs can use together. Its people check on those sheltering in their own damaged homes and bring them supplies, clear roads, and retrieve valuables from collapsed houses.
What is carried out of a fallen house is not only belongings. The years that gathered there, and the memories no one wants to let go of, come out with them. We wanted to entrust what we hold to people who carry both, knowing what they are carrying.
The name Yui comes from “yuimaru,” an Okinawan custom of helping one another with work such as farming.
The ¥100 bank transfer fee for this remittance is recorded under administrative costs. These now total ¥829 (0.18% of donations received).

We sent ¥40,000 to Kumamoto Rosai Hospital, run by the Japan Organization of Occupational Health and Safety.
The hospital, in Takehara-machi, Yatsushiro City, is a core regional hospital and a designated disaster base hospital. It states that its buildings and equipment were badly damaged in the earthquake, and that it has continued to serve as a hub for the area — receiving DMAT teams and supporting local clinics, evacuation centers and facilities for older people.
The money goes toward repairing buildings and facilities damaged by the earthquake, and restoring or replacing medical equipment.
The longer people stay in evacuation, the more of them fall ill. If the side that receives them cannot hold, the weight returns to the whole area. That is where we decided to send part of what we hold.
The ¥73 bank transfer fee for this remittance is recorded under administrative costs. These now total ¥333 (0.08% of donations received).
We asked for, and were given, the hospital’s consent to name it here when we applied.

Donations received have passed ¥400,000.
Thank you to the 21 people who have supported us so far.
The amount received, the amount passed on, and the amount not yet used will continue to be published on this page, as they have been. After we close on October 31, whatever remains will be given in full. -

We have opened a bank account dedicated solely to disaster relief.
Until now the fund sat in our general corporate account, alongside our operating money. With a dedicated account, what you entrust to us no longer mixes with anything else — the statement shows only money in and out for relief.
Donations already made to the previous account are all included in the figures on this page. They will be moved to the new account and reported on exactly the same basis.
The account is an interest-bearing ordinary deposit. Any interest it earns will also go toward relief in the affected area.
Donations from outside Japan are still best made by card, using the button above. -
August 14, 2026
We sent ¥64,271 to Kumamoto Yogo Kyogikai, an association of children’s homes in Kumamoto Prefecture.
Yatsushiro Nazare-en, a children’s home in Yatsushiro City, has opened its showers to local residents around the clock while the water outage continues. Homes across the prefecture are pooling relief supplies and sending staff to keep that going.
As the figures above show, four of the six shelters in Kagami and Sencho still have no running water. Going without a bath wears on people a little more with each passing day. Having somewhere nearby to sit in hot water reaches more than the body.
The funds go toward relief supplies, water and gas bills, and travel costs for the staff sent to help.
We learned of this work through an article by Koumei Douen, a social welfare corporation (in Japanese).
The ¥130 bank transfer fee for this remittance is recorded under incidental costs, bringing the running total to ¥260 (0.06% of donations received). -
August 13, 2026
The fund entrusted to us has passed ¥400,000. Thank you to everyone who has contributed.
Here is what we are hearing about the situation on the ground, from relatives and friends there.
Central Yatsushiro City is said to be recovering. The damage in Kagami and Sencho, however, remains severe, and the gap between districts is widening. This matches the figures above, as of August 12: roughly one in six of everyone still evacuated in the city is in these two districts, and five of their six shelters still have no running water.
We also hear that disaster volunteers who went into Hikawa Town are preparing to deploy to this area. People are finally starting to move toward that last stretch where help has not yet reached.
Half a month has passed since the earthquake — the point at which exhaustion tends to set in. What is needed changes by the day. We will keep providing support in whatever form fits the place and the moment. -
August 12, 2026
We sent a monitor to Yatsushiro Radio (ヤツシロラジヲ), an internet radio station in Yatsushiro City.
The station broadcasts under the motto “telling Yatsushiro as it is now.” Alongside tourism, local events, and culture, it also carries disaster-prevention information. Since the earthquake, it has been broadcasting around the clock through the end of August, reporting on how relief is unfolding across the city.
We learned that their monitor had been damaged in the earthquake and left unrepaired. This is a place where urgent information has to go out urgently. Making it easier for them to concentrate on that work is, we think, one form of support.
There is a last stretch between information and the people who need it. Unless someone covers it, relief does not arrive.
For now the focus is on the disaster. But we hope that, in time, the station will carry more about the region itself — its attractions, its tourism, its economy. Sensing there is something we can contribute to that, we decided on this support.
Yatsushiro Radio from Good-AIR!
The station covers everything about Yatsushiro City in Kumamoto Prefecture — local events and sightseeing, announcements from the city office, PR from local groups, and news from shops around town. As a community that has lived through both the earthquake and flood damage, it also broadcasts disaster-prevention information.
A companion site lets residents post and check, on a map, where relief supplies are being handed out and where people are asking for help. Volunteers are welcome to use it.

We sent ¥67,000 to Save the Children Japan (public interest incorporated association).
The organization held “kodomo hiroba” child-friendly spaces at evacuation centers in Yatsushiro City and at a temple in Hikawa Town. It creates places where children affected by the disaster can spend time safely, and distributes emergency kits for children and school supplies.
What we keep hearing from the ground is that supplies themselves are arriving, but there are not enough people to carry them to those who need them. We judged that entrusting the funds to an organization already working on site is the surest way to reach children right now.
This wording was reviewed and approved by Save the Children Japan before publication. The ¥130 bank transfer fee for this remittance is recorded under incidental costs. -
August 12, 2026
The fund entrusted to us has passed ¥300,000. Thank you to everyone who has contributed.
Here is what we are hearing about conditions on the ground, to the extent it has reached us. Support is spreading from across Japan, and supplies themselves appear to be arriving. What we keep hearing, from more than one source, is that there are not enough people to carry those supplies to those who need them.
There are also moves underway to open more places where children can gather. As soon as the arrangements are settled, we will direct support there. Once it is decided, we will record it here and in the disbursement log. -
August 8, 2026
We have published a crisis map for residents of Kagami and Sencho in Yatsushiro City. It brings together evacuation centers, water distribution points, disaster-waste drop-off sites, and cleanup consultation desks in a single map and list.
Built on advice from people with long experience in disaster response, it was designed around how the information gets updated. It re-reads what Yatsushiro City and the Yatsushiro Living Environment Office Association publish, four times a day (9:00, 12:00, 15:00, 18:00). Every item states when its information was last confirmed. If more than 24 hours pass without an update, a warning appears at the top of the page and directs you to the city's disaster-prevention site.
This is not an official site of Yatsushiro City, and it contains no personal information. For anything decisive, please check the source linked beside each item.
The map is written in Japanese only.

We purchased relief supplies — materials for repairing a collapsed roof. 1,000 sandbags, 1,000 m of banding to secure tarpaulins, and eyelet fittings, shipped directly to the "Kumamoto 10-Year Testimony Archive Project", which is active on the ground.
We chose materials that will hold for a while rather than a stopgap fix. With a typhoon approaching, covering the roof was urgent. -
August 6, 2026
We made our first donation. As our work centres on children, we sent it to "sonaeru", the disaster child-support programme run by Katariba, a certified NPO. In Yatsushiro City, they are running "Minna no Kodomo Beya", a safe space for children, at Ueyanagi Shimoni Community Hall.
A typhoon is now approaching, and the supplies needed on the ground are very likely to change significantly. We will watch how the situation develops before deciding where to send support next. - August 5, 2026 Donations are now open. The donation period runs through October 31. For the time being, the fund status on this page will be updated daily.
We'll still be here after the headlines fade
After the 2016 Kumamoto Earthquake, rebuilding continued for years after media coverage faded.
This time, too, recovery will take a long time. That is exactly why we will stay involved.
We will publish reports whenever we can visit the area.
The timing is not yet decided. When it is, we will post it in Updates.
We will not present anything as decided when it is not.
This page will remain online after donations close.
What the money was used for, and how the area is recovering — it will all accumulate here.
Ways to help beyond money
Donating is not the only way

- Come back to the Updates section now and then. How the fund is used, and reports from the ground, are all posted there.
