When devastating floods struck western Japan in 2018, traditional financial systems moved too slowly for the emergency unfolding on the ground.
But one Binance user used crypto to mobilize global donations in near real time — raising 50 million yen for affected communities.
This is the story of how blockchain became more than technology.
It became a lifeline.
Summary
• A Binance user known as “Miss Bitcoin” helped coordinate flood relief efforts during Japan’s 2018 flood disaster using crypto donations.
• Binance Charity transferred 61.09 BTC — worth 50 million yen at the time — to support local communities.
• The story highlights how blockchain and crypto infrastructure can deliver fast, transparent, and low-cost humanitarian aid.
Market Context
Crypto is often discussed through the lens of markets, trading, and speculation.
But some of the most important blockchain use cases emerge during moments of real human need.
Humanitarian aid remains one of the biggest challenges for traditional financial systems:
International bank transfers can take days
Transaction fees reduce available funds
Cross-border coordination is often inefficient
During emergencies, speed matters.
This is where blockchain infrastructure can fundamentally change how aid moves globally.
The Disaster That Changed Everything
Between late June and mid-July 2018, western Japan experienced one of the country’s deadliest flood disasters in decades.
The floods resulted in:
More than 225 confirmed deaths
Millions of evacuation alerts across 23 prefectures
Approximately 17,000 damaged homes
Entire communities across Hiroshima, Okayama, and Ehime were heavily affected.
As the humanitarian crisis intensified, local aid organizations struggled to move funds quickly enough through traditional channels.
Meet Mai — “Miss Bitcoin”
At the center of this story is Mai, known online as “Miss Bitcoin.”
A Binance user since 2017, Mai had spent years advocating for blockchain-based charity systems in Japan.
Her vision was simple:
Use crypto to make humanitarian aid faster, more transparent, and more efficient.
But before the floods, many local NGOs remained skeptical about crypto-based donations.
The disaster became a turning point.
How Binance Charity Responded
As the crisis escalated, Binance Charity launched a global crypto fundraising initiative to support affected communities.
On July 19, 2018:
Binance transferred 61.09 BTC directly to Mai.
At the time, the value was equivalent to:
50 million yen.
This was not just symbolic support.
It became a real-time operational funding mechanism.
Why Crypto Changed the Outcome
Traditional international bank transfers often require:
3–5 business days
High intermediary fees
Multiple verification layers
Blockchain dramatically reduced those frictions.
Using crypto infrastructure, Mai was able to:
Convert the BTC into Japanese yen
Transfer funds to local organizations
Coordinate emergency support
in near real time.
Transaction costs remained minimal compared to traditional systems.
Where the Funds Went
The 50 million yen was distributed equally between two organizations:
Peace Winds Japan
Received:
25 million JPY
to support:
Emergency supplies
Search and rescue operations
Immediate disaster response
Momotaro Fund (Okayama Share Foundation)
Received:
25 million JPY
to help fund:
Shelters
Mental health support
School supplies
Reconstruction assistance
The Broader Impact
The initiative extended far beyond one transfer.
In total:
Binance Charity raised approximately $1.41 million in crypto donations
More than 41,200 victims received support across affected regions
Since 2018, Binance Charity has expanded its humanitarian initiatives globally:
Over 4 million beneficiaries
Across 86 countries
More than $43.5 million contributed to charitable programs
A Turning Point for Crypto Philanthropy in Japan
Perhaps the most important outcome was the shift in perception.
For many Japanese NGOs, this was their first direct experience using blockchain for humanitarian operations.
What they discovered was:
Transparency
Speed
Global accessibility
Operational efficiency
Following the disaster response, more organizations in Japan began exploring crypto donation systems, with Mai helping guide adoption and setup processes.
More Than Technology — A Community Effort
Mai later reflected that the success of the initiative was not about one individual.
It was about collective action.
“It was the gathering of many people together.”
That philosophy reflects one of the most powerful aspects of crypto communities:
the ability to coordinate globally around shared causes.
Why This Story Matters
The “Humans of Binance” initiative highlights an important reality:
Crypto is not only about markets.
It is also about:
Financial accessibility
Human coordination
Emergency response
Community-driven impact
As blockchain infrastructure matures, its role in humanitarian aid and global philanthropy may continue expanding.
Looking Ahead
Binance’s ongoing user-generated content campaign continues collecting stories from people using crypto in meaningful ways around the world.
Stories like Mai’s demonstrate that blockchain adoption is not only measured by:
trading volume
market capitalization
institutional participation
but also by real-world human impact.
Conclusion
During one of Japan’s deadliest flood disasters in decades, crypto became more than a financial tool.
It became a mechanism for immediate relief, global coordination, and community support.
Mai’s story illustrates how blockchain infrastructure can move beyond speculation to solve real-world problems — especially when speed, transparency, and accessibility matter most.
Sometimes, the most important innovation is simply helping people when they need it most.
