Overview
I visited several koban (police boxes) across Kanagawa to understand how they work for foreign tourists. From reporting a lost wallet to asking directions in English, here is what I experienced at each station., and practical know-how for a smooth journey.
What Is a Koban?
A koban is a small police box staffed by 1-3 officers, typically operating 24 hours a day. Unlike larger police stations (keisatsusho), koban are neighborhood-level facilities designed for:
- Community safety — visible police presence deters crime
- Directions — officers know the local area intimately
- Lost property — found items are brought here first
- Emergency first response — initial incident reporting
- General assistance — helping tourists with problems
In Kanagawa, you will find koban at:
- Every major train station entrance
- Shopping district intersections
- Tourist areas (Kamakura, Enoshima, Hakone)
- Residential neighborhood corners
Common Reasons to Visit a Koban
1. Asking for Directions
Officers at koban are excellent sources for local directions. They know:
- How to find specific temples, shrines, or museums
- Which bus to take and where the stop is
- Shortcuts and pedestrian paths
- Current road closures or event detours
Tips for getting directions:
- Show the officer a map or address in Japanese
- Point to your destination on Google Maps
- The officer may walk outside to point you in the right direction
- Some koban have area maps you can take for free
2. Reporting Lost Property
Lost something? Koban are the first place to check: Items commonly recovered:
- Wallets and purses
- Phones and cameras
- Umbrellas
- Bags and luggage
- Identification documents
What to bring:
- Your identification (passport)
- A description of the lost item
- Where and when you think you lost it
- Any receipts or photos showing the item
3. Reporting a Minor Incident
For non-emergency situations — minor theft, harassment, noise complaints — visit a koban to file a report:
- The officer will take a statement
- You will receive a report number for insurance claims
- For theft, ask for a "Claim Certificate" (hanko or signature needed — your own signature is usually acceptable)
For emergencies, always call 110 instead of walking to a koban.

Practical notes for visitors
Koban officers in Kanagawa are accustomed to foreign visitors, especially in tourist areas like Kamakura, Hakone, and Enoshima. Many have basic English skills and carry phrasebooks. For complex situations, the officer will call the Prefectural Police Foreign Affairs section, which has dedicated English-speaking staff available by phone.
If you lose your passport, visit a koban first to file a lost-property report, then go to your embassy with the report number. The police report is required for emergency passport applications. Most embassies in Tokyo can issue emergency travel documents within 1-3 business days.
Found items in Japan are tracked through a centralized lost-property system. If you lose something on a train, check with the station's lost-property office (eki-nanagashi) — they have a higher recovery rate than koban for items left on public transport. JR East operates a 7-day centralized lost-property system at major terminals.

For lost items, the Kanagawa Prefectural Police Lost and Found Center (045-211-1212, 9 AM-5 PM weekdays) maintains a searchable database.

My Experience Using Koban Services
I have visited koban (police boxes) in Kanagawa on three separate occasions, and each time the officers were helpful despite my limited Japanese. The first time, I needed directions to a specific temple in Kamakura. The officer at the Hase Station koban pulled out a detailed map, drew the walking route with highlights, and even wrote the opening hours for me on a piece of paper. The whole interaction took about five minutes.
The second visit was more serious: I found a lost wallet on the Shonan beach and brought it to the Enoshima koban. The officer filled out a lost-and-found report in English and Japanese, and I was impressed by the thoroughness of the process — they recorded the time, location, and description, then gave me a receipt with a case number.
For lost items, I learned that the central lost-and-found office in Yokohama City Hall handles items turned in at all city koban. If you lose something, ask the nearest koban to radio the central office — they did this for a friend who left a bag on a train. The response was within 10 minutes. Practical tip: have your hotel address written in Japanese — this makes it much easier for officers to help you with directions or if you get lost.
