Help with Japanese phone calls
Delegate a booking, hotel confirmation or everyday phone task to NativeCall. Prefer to speak yourself? Use live phone translation in the app. Choose the route that fits your situation, with the costs, process and limits explained up front.
Routine tasks eligible for AI calling start with AI; tasks requiring human-only handling start with a specialist. Within 24 hours of payment, we complete the phone-call task, including a human call to confirm the outcome or complete the task, and report back in writing. The recipient's hours, availability, and policies still affect whether your requested outcome can be achieved. If it cannot, there is no service fee and any upfront payment is refunded in full.
A connection, an attempt or a report alone does not mean your goal was achieved. Within 24 hours of payment, we complete the phone-call task, including a human call to confirm the outcome or complete the task, and report back in writing. Opening hours, availability, and recipient policies affect the result; the refund promise applies when the goal cannot be achieved. Physical pickup and shipping use a separately agreed schedule.
We can request a new booking. For an existing booking, whether made directly or through another platform, we can request a change or cancellation. The venue or platform decides whether it accepts the request and any cancellation charge.
See how it works →Confirm a reservation, late arrival or a stay request. Share the booking platform and reference so the hotel can find the right record.
See how it works →Share the company, branch, reservation name or number, and preferred new time. We ask whether the change is possible; the rental company still decides the vehicle, charges and branch rules.
See how it works →Ask an electricity, gas, water, internet or service provider for a start date, or schedule a technician when phone booking is available. Provide the address, account details and acceptable times.
See how it works →We can relay a non-emergency repair request to a landlord, or ask a shop whether an item is in stock and can be held. Provide the issue or item, address or product details, and your acceptable boundaries.
See how it works →You can also request routine lost-property enquiries with hotels, businesses, transport operators, or police lost-property offices. Emergencies, crime reports, investigations, and other law-enforcement matters are excluded. Use official multilingual services directly when they meet your needs.
The NativeCall app uses Wi-Fi or mobile data to call supported Japanese telephone numbers. Speak English, Mandarin or Cantonese; the recipient hears Japanese and their reply is translated back. The recipient answers a normal phone call without installing NativeCall.
This fits conversations where you want to answer follow-up questions, compare options or decide on the spot. You need reliable internet, microphone permission and app credits. A data-only plan itself does not provide a voice line; NativeCall supplies the separate internet-calling and translation service.
Performance varies by device, eSIM, network and telephone route; every combination has not been tested. Speech recognition and translation can make mistakes, so ask the recipient to confirm important names, numbers and dates.
| What to compare | Delegated task | Live translated call |
|---|---|---|
| Best fit | You want to hand over a defined task | You want to ask, listen and decide yourself |
| Who joins the call | NativeCall contacts the recipient for you | You call through the app with AI translation |
| Human involvement | Every task includes a human confirmation or completion call | Live voice translation; a human interpreter is not included |
| Payment and outcome | Review the quote before submitting; service fee refunded if the requested goal is not achieved | Uses app credits; check the current charge before calling |
The delegated-task outcome refund promise does not apply to live translated calls. Web task upfront payments are refunded; deducted app task credits are returned. Restaurant deposits, cancellation fees and other third-party charges remain subject to the recipient’s terms.
Japanese number support depends on the route. Do not assume all 0120, 0800 or 0570 special numbers will connect; check the recipient’s official site for an ordinary alternative. Confirm support before requesting destinations outside Japan.
For delegated tasks, leaving our Japanese service number with the business costs an extra US$5. Callback handling is a separate US$5 add-on; both together cost US$10 extra. Both cover the duration of your mission, up to 60 days. Callback handling includes passing messages to you and calling the business back. Arrange the add-ons with us on LINE before payment. This is a service contact number, not a personal Japanese number or SMS verification service.
Delegated tasks follow the service promise within 24 hours of payment, taking the recipient’s opening hours into account. This is not an on-demand human interpreting hotline; disclose urgent deadlines before paying.
Service information updated September 8, 2026. This page describes published product capabilities and service commitments; it does not imply independent verification of every device, telephone route or task type. See each report for the scope of historical recognition tests and task examples.
Ordinary Japanese destinations use 36 credits per billed minute; Japanese mobile numbers (070/080/090) use 60. Each call rounds up to whole minutes, with a one-minute minimum: 2 minutes 1 second counts as 3 minutes. This measures call duration, not speaking time alone.
These examples use the US App Store pack of 500 credits for US$4.99. Dollar amounts represent the approximate value of prepaid credits consumed, not a separate card charge for each call. Buy enough credits first: a 10-billed-minute mobile call needs 600 credits, more than a single 500-credit pack.
| Billed minutes | Ordinary Japan destination | Japanese mobile |
|---|---|---|
| 1 | 36 credits · ≈ US$0.36 | 60 credits · ≈ US$0.60 |
| 5 | 180 credits · ≈ US$1.80 | 300 credits · ≈ US$2.99 |
| 10 | 360 credits · ≈ US$3.59 | 600 credits · ≈ US$5.99 |
The US App Store also lists 3,000 credits for US$24.99: about US$0.30 per billed minute for ordinary destinations or US$0.50 for Japanese mobiles. Starting a call requires at least 120 available credits; this is a balance requirement, not an extra fee. No monthly subscription is required.
Checked September 9, 2026. Storefront, currency, taxes and offers may affect purchase prices; check the app before paying. If you want someone to make the call, leave a Japanese service number, or handle callbacks, that is a separate quoted delegated-task service. View App Store credit packs See delegated tasks
