Shizuoka: Max 60k JPY Subsidy! Hamamatsu/Fukuroi also eligible.
Protecting your family
from water anxiety.
"Reviving the beautiful rivers where we played as children"
Turning free water from the sky into an asset. This is our single-minded answer for 40 years.
Do not turn your eyes away.
Harsher reality surrounding "Water".
Rising water bills, frequent major earthquakes. The sense of security that water will naturally come out when you turn the tap is now about to collapse.
Unstoppable water bill increase
Due to aging infrastructure, water bills continue to rise in Shizuoka. Future increases are inevitable.
Water shortage during earthquakes
In the Noto earthquake, some areas had no water for 5 months. A harsh life waiting at supply points.
"Assets" are raining
on your roof.
A New Asset for Diverse Scenes.
Variations of Rainwater Use
Car Wash & Cleaning
The joy of using water freely without worrying about bills. Perfect for car washing, tiles, and shutters.
Gardening & Crops
Rainwater as a chlorine-free "natural fertilizer". It doesn't damage roots and helps vegetables grow vibrantly.
Emergency Use
Toilet water needs approx 50L/day per person during outage. Stored rainwater protects family daily life.
Cooling (Uchimizu)
Lower ground temp with evening uchimizu. Also helps prevent urban flooding by reducing runoff to rivers.
Why Aikan?
Security DIY can't reach.
Rainwater tanks aren't just for placing. Gutter processing, overflow handling, mosquito prevention. Most importantly, complex subsidy applications. Aikan has pursued all these for 40 years.
