A child car seat is essential when driving with small children, but although it is not against the law to install it in the passenger seat, it is not recommended. Why? In this article, we will explain the reasons and the safest places to install a child car seat.
Why is it not recommended to place a child car seat in the passenger seat?
The main reason why installing a child car seat in the passenger seat is not recommended is the presence of an airbag. In the event of an accident, if the passenger airbag deploys, a large impact will be created between the child car seat and the baby. Because airbags are designed for adults, this can be a very dangerous situation for a baby, and can lead to serious injuries.
The risk is particularly high when the child car seat is installed facing backwards, as the direction of the airbag deployment will be aligned with the baby’s position.
Where can I safely install a child car seat?

The safest place to install a child car seat is in the back seat, where it is less affected by the airbag and can minimize the impact on the baby in the event of an accident.
Among the rear seats, the center seat is considered the safest. Because it is farther away from the left and right doors, it offers high safety in the event of a side collision, and it also has the advantage of making it easier for the driver and passenger to check on the baby.

How to install a child car seat in the passenger seat
It is technically possible to install a child car seat in the passenger seat. If the seat is ISOFIX compatible, it can be secured with the ISOFIX, otherwise it can be secured with the seat belt. However, installing a child car seat in the passenger seat is not recommended for safety reasons.
Cases of people with child seats in the passenger seat

There are a certain number of people who install child seats in the passenger seat. There are various reasons for this, such as the back seat being filled with luggage or not being able to fit two child seats. However, considering safety, it is preferable to install the child seat in the back seat whenever possible.
Things to note when installing a child car seat in the passenger seat
If you are using a car seat in the passenger seat, make sure to disable the passenger airbag. If the airbag deploys, it can create a large impact between the car seat and the baby, which could result in serious injury. Also, make sure to place the car seat as far back as possible and use a forward-facing car seat.
Child car seat safety and its effects while driving
The dangers of child car seats while driving
Child seats are important devices for ensuring the safety of children when installed and used correctly. However, incorrect installation and use can actually be dangerous. Particular care must be taken when installing a child car seat in the passenger seat due to the risk of airbag damage.
Forward-facing vs. rear-facing installation
Child seats can be installed either forward-facing or rearward-facing depending on the child’s age and weight. Rearward-facing is safer for infants whose necks and spines are still developing. Forward-facing seats are recommended for toddlers who have grown to a certain extent.
Relationship with airbags and impacts
When installing a child car seat in the passenger seat, its relationship to the airbag is important. Airbags are designed for adults, so the impact of their deployment can be extremely dangerous for infants and young children. In particular, with rear-facing child car seats, the child’s position is aligned with the direction of the airbag deployment, which can lead to serious injury.
Laws, regulations and the use of child seats
Japanese Laws and Regulations Regarding Child Car Seats
In Japan, the Road Traffic Act requires that children under the age of six must use a child car seat. Drivers who violate this rule will be fined.
Possibility of violating the law when installing in the passenger seat
Installing a child car seat in the passenger seat is not illegal in itself, but installing a rear-facing child car seat without disabling the passenger airbag may be a violation of the Road Traffic Act.
Police crackdown and penalties
Police are cracking down on improper use of child car seats, and drivers who violate the rules will not only be fined but also receive points on their car.
