The Importance of Disaster Toilet Networks in Japan Amid Growing Concerns Over Earthquakes

As Japan grapples with the ever-growing threat of natural disasters, the government has recently updated its estimates regarding potential casualties from massive earthquakes, specifically focusing on the anticipated impact of the Nankai Trough earthquake. Announced in March 2025, the government predicted that in the worst-case scenario, the death toll could reach a staggering 298,000, with approximately 12.3 million people likely to be displaced and economic damages expected to soar to around 292 trillion yen. This alarming projection encompasses major tremors reaching intensity level 7 across a broad area from Shizuoka Prefecture to Kyushu, accompanied by potential tsunamis reaching heights of 30 meters. The announcement sent shockwaves across the nation, prompting media outlets to launch special reports and influencers to delve into speculations about potential earthquake precursors.

Despite the rising public concern being a positive sign, there is a pressing need for discernment and critical information literacy, especially in these trying times. The capacity to accurately interpret information is essential for maintaining calm and ensuring preparedness for future disasters. As residents, it’s paramount to reaffirm our roles in safeguarding families and communities from disaster-related deaths while enhancing our readiness for such incidents.

Recent Developments in Disaster Toilet Network Participation

In May 2025, we welcomed a new addition to the Disaster Toilet Network. Located in Toride City, Ibaraki Prefecture, this municipality is recognized for its vibrant culture and convenient transportation links. With a population of approximately 103,000, the city boasts numerous parks and robust support systems for families and educational environments. The inclusion of this community in our network is a significant step forward in our initiative.

The current participation in the network stands at 32 municipalities, equipped with 134 toilet units capable of accommodating 6,700 evacuees daily. To break this down further, there are 84 trailer-type units, which include four designed for accessibility, and 50 truck-type units. Together, these facilities facilitate 32,000 toilet uses each day, underscoring the critical role they play during emergencies.

Impact of the Noto Peninsula Earthquake

While progress continues in expanding the network, attention must also be paid to ongoing support in response to the recent Noto Peninsula earthquake. As of late April, we deployed three units to support the affected areas, including Wajima City and Suzu City. A total of 37 facilities have benefited from our support as we serve a cumulative total of 339,118 individuals—a testament to the efficacy of our program.

Fundraising Initiatives for Disaster Preparedness

Moreover, the city of Kodaira, Tokyo, has initiated a crowdfunding campaign, addressing the critical need for reliable toilet facilities during disaster situations. Mayor Yoko Kobayashi emphasized the necessity of ensuring that citizens’ dignity is preserved even amidst the challenges posed by disasters. Participation from the public is crucial for the success of this initiative, and support is being actively sought.

In addition, Hirano Town in Yamaguchi Prefecture has launched its crowdfunding initiative to join the Disaster Toilet Network, aiming to create a mutual support system. As disaster-prone areas, such collaborations aim to enhance resilience, ensuring that no municipality stands alone in times of need. Mayor Kunihiro Asamoto has expressed the hope that community spirit will foster widespread support for their efforts.

Conclusion

The expansion of Japan’s Disaster Toilet Network represents a proactive approach to disaster preparedness. With accurate information and community collaboration, we stand better equipped to face future challenges. As participation grows, as do the efforts needed to maintain and enhance these essential services. By working together, we can secure the dignity and safety of every citizen during times of crisis.
