WEAZER Village
The “AREA GRID” Vision
ARTH operates in regions of extraordinary natural beauty—
Nishi-Izu in Shizuoka Prefecture.
Tosa-Shimizu in Kochi Prefecture.
Rich in tourism resources. Blessed with nature.
Yet facing rapid depopulation:
declining birthrates, aging populations, youth migration.
The Funayama hamlet in Nishi-Izu—
home to WEAZER Nishi-Izu—
exemplifies this paradox.
Breathtaking ocean views.
Clear mountain streams.
Lush green forests.
Yet accelerating aging threatens its survival.
A community approaching the brink.
Beyond depopulation lies a deeper crisis:
the deterioration of infrastructure and the decline of essential service providers.
In areas without city gas networks, propane gas cylinders are manually transported and installed at each home.
However, as those workers rapidly age and dwindle in number, the long-term viability of gas supply is increasingly uncertain.
Even more critical: aging water infrastructure.
According to Japan’s Ministry of Land, Infrastructure, Transport and Tourism data:
Currently, about 10% of water pipes have exceeded their service life.
Yet the replacement rate stands at merely 0.15%.
At this pace, particularly in suburban areas,
over half of all water systems will surpass their design life within 20 years — vulnerable to leaks and ruptures at any moment.
Recent incidents—burst sewage pipes in Osaka and Kyoto — serve as stark warnings.
In marginal settlements where populations are aging and shrinking, even infrastructure upgrades become economically unfeasible.
Maintenance costs per capita skyrocket.
The burden far outweighs potential benefits.
Local governments face crushing fiscal pressure.
WEAZER’s Answer
Amid these challenges, WEAZER presents a revolutionary alternative.
WEAZER generates 100% of its energy and water through solar power and rainwater harvesting—eliminating dependence on electricity, gas, or water infrastructure.
Because WEAZER also functions as a hospitality facility, operational revenue funds maintenance, inspection, and system upgrades. A truly sustainable cycle: energy independence meets economic viability.
WEAZER Village: A Vision for the Future
In Nishi-Izu’s Funayama area where ARTH operates, the company is advancing the WEAZER Village concept—installing multiple WEAZER units across the region to create a fully off-grid, decarbonized community.
The vision extends beyond accommodations: residences, restaurants, wellness areas (gyms and saunas) accessible to locals and guests, and agricultural zones—all interconnected, all operating off the grid.
The ultimate goal: for WEAZER to power the entire settlement.
Combining ARTH’s expertise in hospitality development with cutting-edge off-grid technology, pioneering a new model of regional revitalization—sustainable, self-reliant, in harmony with the Earth.
Four Integrated Areas
By establishing multiple off-grid facilities within a single region, area-wide decarbonization and energy autonomy become possible.
Each site shares electricity and water, with software controlling the entire area. The world’s first model for sustainably revitalizing rural settlements where infrastructure maintenance has become difficult.
Energy transportation is performed by electric vehicles. Beyond carrying people and goods, they function as mobile power grids—delivering energy itself.
