The legality of carrying a Samurai sword, or any kind of sword, can vary depending on the jurisdiction and specific laws of the country or region you are in. It is essential to consult the local laws or seek legal advice from authorities in your area to obtain accurate and up-to-date information.

In many countries, carrying a sword in public without a valid reason or proper authorization is generally prohibited. Laws regarding weapons and bladed instruments differ worldwide, and they often classify such items as controlled weapons. Some regions may allow ownership of swords for decorative or ceremonial purposes but restrict their public display or carry.

To avoid any legal issues or misunderstandings, it is crucial to research and abide by the laws specific to your location or consult with local law enforcement authorities for guidance on the matter.
