【New 'Duty of Effort' rule on bicycle helmets!】All cyclists in Japan should wear bike helmets from April 2023 / 全ての自転車利用者にヘルメット着用が推奨されています(令和5年4月から努力義務になりました)

Starting April 1, 2023, a revised section of the Road Traffic Act came into effect, making it a ‘duty-driven effort’ for people of all ages to wear a helmet. In Japanese, the policy is called a matter of doryoku-gimu, which roughly translates to “duty of effort.”
Although there are no legal penalties for not wearing a helmet, data show that the fatality rate in bicycle accidents is 2.1 times higher for those not wearing helmets versus those who do, indicating that wearing a helmet significantly reduces the risk of death.
Everyone who rides a bicycle should wear a helmet for their own safety.

Check and maintain your bicycle regularly / 自転車の点検・整備をしてください

It is important to inspect your bicycle on a daily basis to ensure that the brakes are working properly, that the tires are not worn or flat, and that the lights are working.
If you are unable to check and repair your bicycle yourself, have it serviced at a bicycle store.


About Traffic Safety Mark / 安全安心TSマーク

If your bicycle is inspected or serviced (for a fee) by a certified bicycle safety mechanic, a TS Mark (valid for one year) will be affixed to your bicycle.
Bicycles with this mark are covered by accident and liability insurance.


Bicycle liability insurance has become a legal requirement from July 2022 / 2022年7月から自転車保険加入が義務化されました

In Chiba Prefecture, the "Chiba Prefecture Ordinance on the Promotion of Safe and Proper Bicycle Use" (April 2009) has been revised, making it mandatory to enroll in bicycle liability insurance, etc. for all bicycle riders in Chiba Prefecture from July 1, 2022.

If you are involved in a bicycle accident, you may not only be injured, but you may also injure the other party or cause damage to their property.

 Under the Road Traffic Law, bicycles are a type of vehicle (light vehicle), so in such cases, you are liable for damages to the victim in addition to criminal liability, just as you would be liable for damages to an automobile.

In recent years, the number of accidents caused by "cycling while distracted" (i.e., holding an umbrella, using a cell phone, headphones, etc.) has been on the rise. Because bicycles are a vehicle that can be used by anyone, anyone can be the perpetrator of an accident.

If you happen to be the perpetrator of a bicycle accident, you should have a bicycle insurance (liability insurance) to be prepared to pay compensation to the victim, and to negotiate a settlement between the parties even in the event that you are the victim.

千葉県では、「千葉県自転車の安全で適正な利用の促進に関する条例(平成29年4月)」の改正により、 令和4年7月1日から、千葉県内で自転車に乗る場合には自転車損害保険等へ加入することが義務となりました。


<Caution!> Bicycles can also be held liable if they cause an accident 自転車も、事故を起こせば責任を問われます

Bicycles are vehicles. If a bicycle crashes into a pedestrian, it can kill the person and, like a car, the driver can be criminally charged with gross negligence manslaughter, etc., and may also be subject to civil claims for damages.

Examples of an accident involving a bicycle

  • A fifth-grade boy was riding his bicycle down a hill at night when he collided head-on with a woman who was walking. The woman fell unconscious and suffered a broken skull.
    → The boy's mother was given an order to pay 95 million yen (=approx. 660,000 USD) in indemnification.
  • A high school girl was driving without lights while using her cell phone at night when she collided with a woman. The other party was severely disabled and lost her job.
    →The high school girl (at the time) riding a bicycle was ordered to pay approximately 50 million (=approx. 350,000 USD) yen in indemnification.



  • 小学5年生男児が夜間、自転車で坂を下り、歩行中の女性と正面衝突。相手の女性は頭の骨を折るなどし、意識が戻らない状態となった。
  • 女子高校生が夜間、携帯電話を操作しながら無灯火で走行中、女性と衝突。相手には重大な障害が残り、職を失った。
