OUR MISSION

OUR PROMISE

~A once-in-a-lifetime encounter forged through travel~

In April 2026, we took a new step forward as a charter bus operator.

For our customers, this may be a once-in-a-lifetime trip to Japan. Our wish is for you to create lasting memories of that irreplaceable time.

In addition to safe and comfortable travel, we cherish each encounter with our passengers and provide heartfelt hospitality.

"I'm glad I came to Japan. I want to visit again."

To carry that smile on to the next journey,

We will continue to run today with the spirit of cherishing each encounter as a once-in-a-lifetime opportunity.

MAINTENANCE & SAFETY

Before even starting to run,
Creating safety

Operation and maintenance handled by a single company.

Air Support Co., Ltd. operates a vehicle maintenance business in addition to its charter bus business. Through daily inspections and maintenance, we strive to detect even minor abnormalities early and support safe operation with a preventative maintenance approach that prevents problems before they occur.

We provide peace of mind to both travel agencies and customers through our expertise in both vehicle maintenance (understanding the vehicle's condition) and operational planning (understanding the route).

OUR FLEET

FOR TRAVEL AGENTS

~To Our Agents~ We may not have the most state-of-the-art vehicles like some other companies. However, we pride ourselves on our unwavering commitment to supporting your important journeys and our passion for daily operations. Precisely because we don't have the latest vehicles, our representative, who has a thorough understanding of their structure, personally handles daily maintenance, minor malfunctions, and parts replacements, striving to ensure everything is in perfect condition before departure. Unexpected troubles and changes are inevitable in the inbound tourism industry. That's why, even in the event of an emergency, we will never give up. With the skills and integrity we have cultivated over the years, we will quietly protect the success of your tour until the very end. With the spirit of the rice plant, "the more fruitful the rice plant, the lower its head bows," we deeply bow our heads in devotion to your valued customers. KasumiJapan is a partner that promises such honest and reliable peace of mind.
