What Happened on the Train
At 2:15 p.m. on June 19, a passenger on the Hokuriku Shinkansen noticed a knife handle protruding from another traveler’s backpack. The passenger alerted a crew member, who reported the incident to police. The train, traveling from Tokyo to Kanazawa, stopped at Omiya Station in Saitama. Police officers boarded and found a knife wrapped in a bag inside a 30-year-old man’s backpack. No one was injured.
Why Police Did Not Arrest the Man
Japan’s Firearms and Swords Control Law bans carrying blades longer than 6 centimeters without a valid reason. The law allows exceptions for work, moving, and purchasing. The man told police he was transporting the knife as part of a move. Police accepted his explanation and found no evidence he intended to harm anyone. The man received a warning about public safety but faced no charges.
The Difference Between Legal and Alarming
The incident highlights a gap between law and public concern. The passenger who reported the knife acted correctly. Train safety depends on vigilance. However, the man’s legitimate reason for carrying the blade meant no crime occurred. Police warned him to keep the knife hidden to avoid alarming other passengers in the future.

The Hokuriku Shinkansen train number 537 resumed service at 2:35 p.m. after police completed their check. About 600 passengers experienced the delay. JR East, the train operator, confirmed no injuries and normal operations resumed.
Final Thoughts
The June 19 knife incident shows how Japan’s weapons law allows legitimate blade transport for moving and work. Police correctly balanced public safety with legal rights. Passengers should continue reporting suspicious items, but the man’s lawful reason meant no arrest was warranted.
