Japan is increasingly popular as an expat destination, particularly following the launch of its Digital Nomad Visa and various skilled worker pathways. Internet infrastructure is world-class — Japan consistently ranks in the global top three for internet speed. The administrative process for setting up local services is more documentation-heavy than most countries, with the Residence Card being the key document.

This guide covers the complete connectivity arc for expats moving to Japan — from the moment you land to having reliable home broadband set up and everything in between.

Step 1: Before You Leave — Activate Your eSIM

The single most important connectivity action before moving to Japan is activating a ConnectPls eSIM. Land at your destination airport already connected. Navigate to your accommodation, coordinate with landlords or relocation agents, and handle all arrival-day logistics with working data — not airport WiFi or expensive roaming charges.

Step 2: The Residence Card (zairyu card) — Why It Matters for Connectivity

The Residence Card (zairyu card) is the gateway to most Japan services. Without it, you typically cannot open a local bank account, sign a postpaid phone contract, or set up fixed broadband with most providers. Obtaining it requires a confirmed local address and a visit to the relevant authority — the process typically takes 4-6 weeks. During this entire period, your ConnectPls eSIM or SIM card subscription keeps you fully connected without any local documentation.

Step 3: SIM Card — Once You’re Settled

For the first few weeks in Japan, a ConnectPls SIM card subscription gives you a local +81 number and better data value than the eSIM for extended use. ConnectPls SIM cards for Japan don’t require Residence Card (zairyu card) — they work immediately, giving you local network access while you complete the administrative setup.

Step 4: Home Broadband — The Long-Term Solution

For stays of 3 months or longer, fixed broadband in your Japan home is the most reliable and cost-effective connectivity solution. NTT Docomo, SoftBank, and au (KDDI) and other local providers offer packages typically priced at 30-50 euros per month. You’ll need your Residence Card (zairyu card) and a confirmed address for the contract. Once your broadband is live, scale back your ConnectPls subscription to mobile-only for out-of-home use.
