“SAFETY ,SECURITY and COMFORT” is Our Pride

Kurobe river is known as rampage river which flows fast in the steep and narrow slope.
Since the establishment of Otaka , our main works like flood protection project to protect the lives and property of people in the basin suffering from flood damage and for the power supply development by overcoming the harsh natural environment.
The thoughts of predecessors who challenged these are still taken over by us.
The development of social infrastructure has progressed and “ safety,security and comfort” has become common today. In other to protect the present status we are and we will play a big responsibility with our high technology both today and in the future. That’s OTAKA’S Pride
