For safe flights

We advise all passengers to keep their seatbelts fastened whenever they are seated.

We advise all passengers to keep their seatbelts fastened even after the pilot has turned off the fasten seatbelt sign. Aircrafts takeoff and land at a speed of approximately 300km per hour. In cases where an unexpected accident occurs or an emergency stop is required during takeoff or landing, a great deal of force will be applied to the aircraft.
If passengers do not keep their seatbelt fastened, they are at risk of being thrown forward from their seat. In addition, the aircraft may also shake violently while in-flight due to unexpected turbulence. For this reason, the fasten seatbelt sign will be turned on during takeoff and landing and when turbulence is anticipated. Please fasten seatbelts as soon as the fasten seatbelt sign is turned on.
We advise all passengers to keep their seatbelts fastened whenever they are seated, even while the fasten seat-belt sign is turned off.

Under the Law, violations including "refusing to fasten seatbelts" or "refusing to return seatbacks to the locked position" may result in the levy of a penalty of up to ¥500,000 against any offender who continues or repeats these actions after being asked to cease by the pilot.
Q.
What is the fasten seatbelt sign?
A.
In the event of an unexpected accident, emergency stop, or other emergency situation during takeoff or landing, a great deal of force will be applied to the aircraft. If passengers do not keep their seatbelt fastened, they are at risk of being thrown forward from their seat. In addition, the aircraft may shake violently while in-flight due to unexpected turbulence. For this reason, the fasten seatbelt sign will be turned on during takeoff and landing and when turbulence is anticipated. We advise all passengers to keep their seatbelts fastened whenever they are seated.
Cabin crew will check if passengers keep their seatbelts fastened to ensure passenger safety. Please keep your seatbelt fastened over your blanket while sleeping so that cabin crew can check more easily.
Q.
Can we unbuckle our seatbelt after the fasten seatbelt sign is turned off?
A.
While we would like for passengers to be able to unbuckle their seatbelt for a more relaxing and pleasant flight after the fasten seatbelt sign has been turned off, regrettably it is not possible as the aircraft may encounter a sudden change of airflow while in flight. If your seatbelt is unbuckled because the fasten seatbelt sign has been turned off, it may cause injury or other problems. Please keep your seatbelt fastened whenever you are seated, even after the pilot has turned off the fasten seatbelt sign.
Q.
How do we fasten the seatbelts?
A.
We advise passengers to keep seatbelts fastened securely around the lower abdomen across the hips bones without any slack or twisting. If seatbelts are loose, it may cause the body to slide out from underneath the seatbelt (submarine phenomenon), or injury to the abdomen (jackknife phenomenon). In addition, when returning reclined seatbacks to the upright position during takeoff and landing, the seatbelt will loosen. We ask passengers to check their seatbelts to make sure that they are tightly fastened once again at this time.
For small children, a loose seatbelt can be adjusted by putting a blanket around their waist. Please ask a cabin crew member for blankets.
In case of an emergency evacuation, seatbelts will need to be unbuckled. We advise passengers to make sure they know how to unbuckle their seatbelts beforehand.
Q.
Does the cabin crew fasten their seatbelts when the fasten seatbelt sign is turned on?
A.
When the fasten seatbelt sign is turned on while in flight, not only passengers, but the cabin crew as well must take their seats and fasten their seatbelts for their safety. They also take their seats and keep their seatbelts fastened in cases of sudden braking or other actions while taxiing, unless they are working on safety or security related tasks. In the case of turbulence or anticipated turbulence, cabin crew are required to fasten their seatbelts for their safety as well, and may be unable to check if passengers keep their seatbelts fastened during this time. In this case, we ask passengers to make sure their seatbelts are securely fastened. We appreciate your cooperation.

Returning seatbacks to the upright position and stowing tray tables in the locked position

Before takeoff and landing, we ask all passengers to return their seatbacks to the upright position and to stow tray tables in the locked position. In an emergency, a reclined seat is an obstacle to the passengers seated behind, and may hinder their ability to evacuate safely and quickly. It also prevents them from taking the appropriate shock prevention posture.
Furthermore, when a seat is reclined, the seatbelt cannot be fastened securely and the body may slide underneath the seatbelt during an emergency stop (submarine phenomenon). A great deal of forward force will be applied during an emergency stop, if seats are not returned their full upright position, passengers will be shaken more violently and risk being thrown hard against the seat in front of them. Also, if tray tables are not stowed properly, passengers may be injured hitting them. Even if the seat behind you is empty, we ask you to return your seatbacks to their upright and locked position.
Before takeoff and landing, we ask all passengers to return their seatbacks to the upright position and to stow tray tables in the locked position to thoroughly prepare the cabin for emergency procedures if they become necessary.
