About our environmental contribution activities

Fixed-route Bus

Charter Bus


Since the first purchase of a bus with automatic idling stop system in 1996, Kokusai Kogyo has expedited bus replacement with new ones that satisfied the emission requirements. Even after 2002 when the more strict regulations became effective, we have not slowed down the purchase of eco-friendly vehicles equipped with the latest emission reducing devices. Now, over 60% of our fleet is “Green Busses”. We will increase the share of green buses and promote eco-driving training for our bus drivers. As a corporate citizen aiming to share prosperity with the local communities, we will proactively take all available actions for environmentally friendly corporate management.
