Ronan Law

In England, the 2022 killing of 16-year-old Ronan Kanda in Wolverhampton by attackers who mistook him for someone else using a ninja sword (katana) has sparked widespread shock and triggered a strong public road. Despite Ronan not being the intended target of the attackers, his death led the British government to draft legislation known as the “Ronan Law” to bring sharp weapons posing a threat to public safety under control. August 1 August 2025, the law aims to prevent similar tragedies by banning the production, sale, import and possession of katanas and similar sharp weapons.

Purpose and Scope

In June 2022 in England, the killing of 16-year-old Ronan Kanda with a ninja sword (katana) generated deep sadness and public outrage. Following this incident in Wolverhampton, growing incidents of knife attacks especially among young people drew attention, and significant pressure was exerted by people for stricter measures to control sharp weapons. Ronan’s family, through campaigns launched after their son’s tragic death, applied pressure on the law system and gathered widespread public opinion support.

In response to this public pressure, the British government drafted the Ronan Law to strictly regulate the carrying, possession and sale of sharp weapons, particularly the katana known as a ninja sword. The primary aim of the law is to prevent the recurrence of similar tragic events, ensure the protection of young people from such attacks, and permanently enhance society safety. Under this law, restrictions on the use of such weapons in public and private spaces have been clearly defined, with the goal of strengthening public perceptions of security.

Definitions

The primary weapon targeted under the Ronan Law is the Japanese-origin long, commonly known as a katana—a curved, single-edged sword. As a war instrument unique to Japanese samurai culture, the katana is now mostly used for collection purposes or cultural events. However, in recent years, its increasing use in crime activities has been identified as a serious public safety threat.

Under this law, katanas and other sharp weapons with similar designs are defined in detail. This definition includes length, blade structure and design features, aiming to eliminate ambiguity in enforcement. As a result, law enforcement and the public are provided with clear and consistent information regarding which types of weapons fall under the law’s ban scope.

Bans

The Ronan Law comprehensively prohibits the manufacture, sale, import and possession of specific sharp instruments. In particular, the carrying, display or use of long, sharp weapons such as ninja swords and similar blades in public spaces are subject to strict rules and oversight. Since possession of such weapons in public areas is considered a threat to public safety, violations are subject to serious penalties under the law.

Furthermore, the sale, marketing and purchase of weapons specified under the Ronan Law via online platforms are entirely banned. To prevent unlawful online activities, online sales channels will be closely monitored, and severe criminal penalties are foreseen for individuals and organizations engaging in illegal sales. These bans aim to prevent the emergence of potential threats and halt the uncontrolled spread of weapons.

Criminal Provisions

Individuals and organizations violating the Ronan Law will face serious legal penalties. The law enables courts to impose prison sentences on those who illegally produce, sell, import or possess the specified sharp weapons. Penalties vary according to the severity and nature of the offense, typically ranging from six months to up to two years imprisonment.

In cases of repeat offenses or aggravating circumstances, courts may increase the penalties imposed. Aggravating factors include organized commission of the crime, commercial use of the weapons or direct threats to vulnerable groups such as children. The Ronan Law aims to significantly reduce crimes that seriously threaten public safety by ensuring penalties are applied in a deterrent and effective manner.

Transition Period and Weapon Surrender

Before the Ronan Law comes into effect, a transition period has been implemented to facilitate public compliance. During this period, individuals currently in possession of the banned sharp weapons are encouraged to surrender them to authorized authorities. Extensive public awareness campaigns have been conducted, and local administrations have supported efforts to inform citizens on this matter.

Centralized country collection centers and specially designated surrender points have been activated across the country. No criminal sanction has been applied to weapons surrendered voluntarily during this period, ensuring citizens can safely hand over their weapons. This approach has been regarded as an effective vehicle for promoting public acceptance of the law and preventing illegal weapon use.

Exceptions

The Ronan Law includes various exceptions and exemptions for specific situations and institutions. Under these provisions, museums, art galleries, historical collections and official educational institutions may be exempted from the law when the weapons are used for cultural heritage preservation or educational purposes. The aim of these exceptions is to ensure that cultural values and historical heritage are preserved without disruption to educational activities.

However, the application of these exceptions is subject to strict oversight and requires special authorization from competent authorities. Institutions must demonstrate compliance with established criteria to possess and use the specified sharp weapons. Authorized institutions are required to implement necessary security measures and undergo regular inspections. This strict oversight mechanism is essential to prevent abuse of exemptions and safeguard public safety importance.

Entry into Force

The Ronan Law will officially enter into force on 1 August 2025. From this date, all provisions and criminal penalties of the law will be enforced. Prior to its implementation, the law has been widely publicized through public awareness campaigns and coordinated efforts with local authorities and security forces. This process aims to ensure that citizens and relevant organizations understand the law’s requirements and comply with it complete.

Before the enforcement date, necessary infrastructure are being established to allow citizens and organizations to surrender prohibited weapons without any criminal proceedings. Thanks to these comprehensive preparatory and informational efforts, the transition to implementation is intended to proceed smoothly and active. This approach will contribute to increased public awareness of the law and strengthen the public’s security sense of security.
