Overview

CC routes to Japan

CC routes to Japan are tuned for dialer traffic: high call attempts, short average durations and bursts at shift start. We size capacity per campaign and watch short-call ratios, so your traffic stays welcome on the terminating networks.

Dialer traffic to Japan works best at low pacing with strong scripts, because aggressive dialing drives complaints quickly. CC routes support conservative concurrency caps and per-number answer-rate monitoring.

Japan is a high-ARPU destination with strict consumer protection and a culture that strongly favours known numbers. International-origin calls are widely screened, so expect lower ASR than in Europe.

Caller ID rules in Japan

A practical summary for operations teams, not legal advice. Confirm current requirements with counsel before you launch.

Last reviewed

Caller-ID presentation

Japanese carriers display the presented number when it is a valid MIC-allocated Japanese number. Calls arriving from abroad are commonly flagged as international, and MIC has pressed carriers to curb international calls that falsely present Japanese numbers.

Act on Specified Commercial Transactions

Telephone solicitation must state the business name, caller name and purpose at the start of the call. Once a consumer declines, you must not call again for the same offer.

Number allocation

Number ranges are allocated by MIC. 050 numbers are IP telephony numbers and are common for business lines.

APPI

The Act on the Protection of Personal Information covers call lists and recordings, including transfers of data abroad.

Calling hours

No single statutory window. Consumer guidance discourages early-morning and late-evening sales calls.

Dialing & setup

Dialing Japan correctly

  • Drop the trunk 0: 090-1234-5678 becomes +81 90 1234 5678.
  • 0120 and 0800 freephone numbers are not reachable on international routes.
  • Golden Week (late April to early May), Obon (mid-August) and New Year (late December to early January) cut business-hours answer rates sharply.
  • Use Japanese-speaking agents and state the company name, caller name and purpose in the first sentence, as the law requires.

Caller ID best practice

Present a Japanese number you hold, typically 03 (Tokyo), 06 (Osaka) or an 050 IP number that reaches your team. Japanese carriers flag or block calls with invalid CLIs.

FAQ

Japan CC routes: FAQ

Can’t find what you need? Our routing team answers within the hour, around the clock.

Why is ASR to Japan lower than to Europe?

Japanese subscribers screen unfamiliar numbers heavily, and many handsets warn on international-origin calls. A clean local CLI and calling during business hours help most.

Can I present an 050 number?

Yes, if it is allocated to you. 050 numbers are widely used for business IP lines in Japan and display normally on handsets.

Do I need Japanese-speaking agents?

In practice, yes. The law requires you to identify the business and the purpose at the start of the call, and English-first calls are usually ended immediately.

Which holidays affect Japanese traffic?

Golden Week, Obon and the New Year period. Many businesses close for several days, so B2B campaigns should pause or switch to callbacks.

Can I call 0120 numbers on your routes?

No. Japanese freephone numbers only accept calls from domestic networks. Ask the business for a geographic or 050 number instead.

Can I run predictive dialers to Japan?

Yes, for lawful campaigns. Set conservative pacing, follow Japan’s calling hours and opt-out rules, and keep your abandoned-call rate low. CC routes report short-call ratios per campaign so you can tune pacing with real data.
