What is a virtual Japanese phone number?
A virtual Japanese phone number is a cloud-based phone line that lets your team make and receive incoming calls in Japan from anywhere in the world—no physical office, local SIM card, or hardware necessary. Unlike traditional phone lines that use a specific location or device, virtual numbers use voice over Internet protocol (VoIP) to route calls over the Internet.
You can pair these numbers with enterprise-grade features like call recording, voicemail, SMS, and interactive voice response (IVR) to enable scalable communication for everything from sales outreach to customer support.
For growing businesses, virtual numbers offer a cost-effective, flexible alternative to traditional providers. They also allow you to activate lines by area code or national coverage through a single cloud platform.
Types of Japanese virtual phone numbers
Japan offers several types of virtual numbers, and each supports different business goals:
Japanese toll-free numbers
Toll-free numbers (like Japan’s 0120 prefix) allow customers to call you at no cost, which makes them ideal for support lines and customer care. Universal international freephone numbers (UIFNs) make your business accessible across multiple countries, including Japan, under a single global, toll-free number.
Japanese local phone numbers
DID and national Japanese numbers can help you establish a presence in Tokyo, Osaka, and beyond with city-specific or national coverage. These numbers are ideal for local credibility and improved answer rates.
Japanese mobile numbers
These numbers give your customers the option to call a recognizable mobile prefix, which is best for mobile-first markets and more flexible communications.
Analyze and automate your calls
Modern global teams need more than basic call routing—they also need smart tools that adapt to changing demand, customer needs, and team availability.
AVOXI gives you flexible control and visibility across every call path with the following features:
Custom call forwarding
Forward calls to mobile devices, landlines, VoIP phones, or SIP endpoints to support hybrid teams, after-hours coverage, or region-specific sales queues.
AVOXI makes it easy to create flexible call forwarding rules based on time of day, geography, or team assignment—no manual routing necessary. Whether you’re managing a 24/7 support line or balancing call volume across time zones, AVOXI helps you route calls more intelligently.
IVRs with intelligent routing
Design and update cloud IVRs in minutes with AVOXI’s Flow Builder. You can then route calls by team, time, volume, or custom rules across over 150 countries.
Multilingual menus, custom greetings, and unlimited flows allow you to create personalized experiences. Advanced analytics also allow you to measure performance, which frees your agents for high-value conversations.
Real-time call analytics
Track what’s happening across your voice channels with real-time dashboards that surface metrics like call volume, duration, answer rate, and voice quality (including MOS scores).
With visibility into call performance across teams and regions, IT and contact center leaders can make informed decisions about staffing, routing rules, and customer experience improvements.
Reach your Japanese customers
Your ability to connect with customers in Japan depends on how local you sound, how reliably you deliver calls, and how confidently you navigate local telecom regulations. AVOXI helps you do all three with the following features:
Localized presence
Increase your answer rates and build customer trust with localized outbound caller ID.
AVOXI's TrueLocal™ feature ensures that your calls display a recognizable Japanese number, which improves deliverability and reduces the chances that customers will ignore your calls or mark them as spam. Whether you're supporting customers or selling into new markets, showing up as "local" makes all the difference.
Compliance-ready global voice
Meet documentation requirements, stay compliant with telecom laws, and get your numbers live faster.
Japan has some of the most complex voice regulations in the world-but AVOXI makes them manageable. Behind the scenes, our global provisioning team ensures carrier-grade redundancy so your voice service remains secure, stable, and enterprise-ready.
24/7 global support
Get support for all your virtual number needs, whenever you need it.
