The official FAQ says to call 045-788-9646 from the next day, and notes that if the person in charge is unavailable and the call does not connect, try again later.
Before you call
- If you are still on the island on the day of the loss, ask at the nearest Information desk first; call the dedicated line on 045-788-9646 from the next day.
- The phone answers 10:00-17:00.
- When you call, give the date of your visit and a description of the item, which the official FAQ specifically asks for.
- If the person in charge is unavailable and the call does not connect, the operator suggests trying again after some time.
Yokohama Hakkeijima Sea Paradise splits the process in two: ask at an Information desk on the island on the day of the loss, and call the lost property line from the next day. The dedicated number is 045-788-9646, answered 10:00-17:00, and the official FAQ asks for the date of your visit and a description of the item. If nobody is available and the call does not connect, the operator asks you to try again later rather than assume the item is gone.
Call script: Japanese, romaji and English
Replace every ◯ with your own date, number and name. These are example lines, not a promise from the office: whether the item is found, and the rules for pickup or shipping, are decided by the desk that holds it.
First inquiry: date, place and a description of the item

Common questions
Can I call in English?
Call to confirm which languages the phone line supports; the official site has multilingual pages. If the desk cannot handle the call in English, use the Japanese script below and ask them to speak slowly; language support can change, so confirm the current situation on the official page.
When is it easiest to get through?
Call right after the line opens at 10:00, or in the hour before it closes at 17:00. Lunchtime (12:00–13:00) is often unanswered. Open every day of the year; opening arrangements and temporary closures still follow official notices.
What happens after a week?
There is no single national rule: the office decides how long it keeps an item and when it is passed to the police or another desk. The official FAQ says to call 045-788-9646 from the next day, and notes that if the person in charge is unavailable and the call does not connect, try again later. If the item has not been found yet, ask which desk is holding it now, for a reference number, and how long it will be kept.
Can someone collect or ship it for me?
The office decides whether a proxy can collect the item and which ID or authorization is required. If you have already left Japan, ask whether it can be shipped within Japan or overseas, and confirm the conditions and cost with the office. The collection script below has the questions to ask.
What is Native Call?
You can speak English, Mandarin, or Cantonese. The person in Japan hears Japanese, and their Japanese reply is translated back into your selected language.
- 1
Open the app and enter a supported Japanese number. International calling is built in; no Japan SIM needed.
- 2
Take turns speaking. Translation delay varies with the network, phone route and utterance length.
- 3
Repeat names, dates, times and outstanding steps before hanging up. A connected call does not prove the request was completed.
