Japan launched its Digital Nomad Visa in 2024, making it significantly more accessible for remote workers wanting to experience one of the world’s most extraordinary countries. Internet infrastructure in Japan is world-class — consistently ranking in the global top five for both fixed and mobile speeds.

This guide covers everything a remote worker needs to know about internet connectivity in Japan — from the moment you land to having a fully optimized setup for professional remote work.

Mobile Coverage for Remote Workers in Japan

NTT Docomo, SoftBank, and au (KDDI) dominate Japan’s mobile market. In Tokyo and other major cities, coverage is consistently strong with solid 4G and expanding 5G. For remote workers, mobile data from a ConnectPls eSIM or SIM card serves as both the primary connection for phone-based work and a backup when fixed broadband is unavailable.

eSIM: The Remote Worker’s Arrival Solution

A ConnectPls eSIM activated before your flight gives you working Japan data from the moment you land. Navigate to your accommodation, coordinate with co-working spaces, and start your first remote work day in Japan without any connectivity gap. No carrier shop visit, no registration queue, no language barrier.

SIM Card: Best Value for Longer Remote Work Stays

For remote work stays over a month, a Japan SIM card gives you a local +81 number and better long-term data value. ConnectPls SIM card subscriptions for Japan provide local network access with the convenience of setup from home — no arrival-day carrier shop visit, manageable in English.

Portable WiFi: Multi-Device Remote Work Coverage

Remote workers typically need connectivity on multiple devices simultaneously — laptop, phone, tablet. A ConnectPls portable WiFi subscription creates a private hotspot covering all your devices from one plan. Particularly useful during the first weeks in Japan before fixed broadband is arranged, or for working from cafes and co-working spaces without using the venue’s potentially slow shared WiFi.

Fixed Broadband for Extended Remote Work Stays

For remote work stays of 3 months or longer, fixed broadband in your Japan apartment or flat is the most reliable and cost-effective solution. Most residential areas in Tokyo and major Japan cities have fibre broadband available. You’ll typically need a local address and some local documentation to set up a fixed contract — during the wait, ConnectPls covers all your connectivity needs without any gap.
