Last Updated: August 8, 2026 | Reading time: 14 minutes

Introduction: Why a Physical SIM Still Matters in 2026

In 2026, eSIM has become the default choice for most travelers with modern smartphones. It’s faster, more convenient, and often cheaper. But what if your phone doesn’t support eSIM? What if you’re traveling with an older device, or you simply prefer the familiarity of a physical card?

Physical SIM cards are still widely available across Japan — and for many travelers, they remain the most practical option.

This guide covers everything you need to know about buying a Japan SIM card in 2026: where to find them, how much they cost, which providers offer the best value, and how to set one up when you arrive.

If your phone does support eSIM, you might want to check our Japan eSIM Ultimate Guide instead. But if you need a physical SIM — or just want to know your options — read on.

Quick Answer: Should You Get a Physical SIM or eSIM?

If you have…	Best option
A modern phone (iPhone XR or newer, Samsung S20 or newer, Pixel 3 or newer)	eSIM — buy before you fly, activate on arrival
An older phone without eSIM support	Physical SIM — buy at the airport or an electronics store
A carrier-locked phone	Neither — you need an unlocked phone first
A group traveling together	Pocket WiFi — share data across multiple devices

For most travelers in 2026, eSIM is the easiest and most affordable option. But physical SIM cards remain a reliable fallback — and in some cases, they’re still the best choice.

Part 1: Types of Japan SIM Cards for Tourists

Data-Only SIM Cards (Most Common)

Data-only SIM cards provide mobile internet access without a phone number. They’re the most popular choice for tourists who plan to use messaging apps (WhatsApp, LINE, WeChat) and VoIP calls (Skype, Google Voice) rather than traditional calls.

Best for: Most tourists, short-term visitors, and anyone who doesn’t need a Japanese phone number.

Price range: ¥1,500–¥4,000 ($10–$27 USD) for 7–30 days

Voice + Data SIM Cards

These SIM cards include a Japanese phone number, allowing you to make and receive traditional calls and SMS. You’ll need one if you plan to make restaurant reservations, rent a car, or use services that require SMS verification.

Best for: Long-term travelers, expats, business travelers, and anyone who needs a Japanese phone number.

Price range: ¥3,000–¥10,000+ ($20–$70+ USD), depending on data allowance

Unlimited Data SIM Cards

Some providers offer “unlimited” data plans. However, as with eSIMs, “unlimited” often means a daily soft cap (typically 2–5 GB per day) after which speeds are throttled. Make sure to read the fine print before purchasing.

Best for: Heavy data users, streamers, and remote workers.

Price range: ¥4,500–¥15,000 ($30–$100+ USD)

Part 4: How to Buy and Activate a Japan SIM Card

Step 1: Check Phone Compatibility

Before buying any SIM card, confirm two things:

1. Your phone is carrier-unlocked — check with your home carrier
2. Your phone supports the correct SIM size — most modern phones use nano-SIM

Step 2: Bring Your Passport

Important new rule for 2026: Since April 1, 2026, Japan’s Ministry of Internal Affairs and Communications (MIC) has required a passport or residence card ID for every SIM and eSIM purchase — including data-only plans.

You will not be able to buy a SIM card in Japan without showing your passport. This applies to airport counters, electronics stores, and convenience stores alike.

Pro tip: Keep your passport on you when shopping for a SIM. Digital copies or photos are not accepted — you need the physical document.

Step 3: Choose Your Plan

Decide on your data needs based on your trip length:

• 3-5 days: 1-3 GB
• 7-10 days: 3-7 GB
• 14+ days: 7-15 GB or unlimited

Step 4: Purchase and Activate

At airport counters or electronics stores:

1. Find the SIM card section or counter
2. Show your passport
3. Choose your plan
4. Pay (credit cards and cash accepted)
5. The staff will help you insert and activate the SIM card

At convenience stores:

1. Find the SIM card display (usually near the register)
2. Take the package to the counter
3. Show your passport
4. Pay and follow the instructions inside the package

Step 5: Configure APN Settings

Most SIM cards require manual APN (Access Point Name) configuration. The APN settings are usually printed on the card or included in the package instructions.

Common Japan SIM APN values:

Provider	APN	Username	Password	Auth Type
b-mobile	bmobile.ne.jp	(blank)	(blank)	None
IIJmio (BIC SIM)	iijmio.jp	mio@iij	iij	PAP or CHAP
Mobal	mobal	(blank)	(blank)	None
Sakura Mobile	sakura	(blank)	(blank)	None
NTT Com	prepaid.ezweb.ne.jp	(blank)	(blank)	None

On iPhone:

1. Settings → Cellular → Cellular Data Network
2. Enter the APN, username, and password from the instructions
3. Save and restart

On Android:

1. Settings → Connections → Mobile Networks → Access Point Names
2. Add a new APN with the settings from the instructions
3. Save and select the new APN

Step 6: Test Your Connection

Once activated, open a browser or app to confirm data is working. If not, double-check the APN settings or restart your phone.

Part 5: When to Choose a Physical SIM Over eSIM or Pocket WiFi

Choosing between a physical SIM, eSIM, and pocket WiFi depends on your specific travel situation. Here’s a detailed decision guide:

Choose a Physical SIM if:

• Your phone does NOT support eSIM — the most common reason. Check with *#06# on your phone’s dialer. If you see an EID number, your phone supports eSIM. If you only see IMEI numbers, it does not.
• You’re buying a voice-enabled plan — eSIMs rarely include a Japanese phone number. If you need one for reservations or verification, a physical SIM from Mobal is often the simplest way.
• You prefer the familiarity of a physical card — some travelers simply prefer having a tangible product they can swap between devices.
• You plan to use the SIM in multiple devices — you can easily move a physical SIM between phones.
• You want to keep your home SIM in the phone — physical SIM + eSIM are both options, but if you want to keep the physical slot open for other travel SIMs, consider eSIM instead.

Choose eSIM if:

• Your phone supports eSIM and you want the convenience of installing before travel.
• You want to keep your home SIM active for calls and SMS while using the eSIM for data.
• You don’t want to carry your passport while shopping — eSIM can be bought online before travel.
• You’re a solo traveler or couple — eSIM offers the best cost-to-convenience ratio.

Choose Pocket WiFi if:

• You’re traveling with a group of 3 or more — one device covers everyone, often cheaper than multiple SIMs.
• You need to connect tablets and laptops — a pocket WiFi router can connect multiple devices simultaneously.
• You don’t want to worry about phone compatibility — pocket WiFi works with any WiFi-enabled device.

Final Thoughts: Your Japan SIM Card Checklist

Before your trip:

• Check your phone is carrier-unlocked
• Check your phone’s SIM card size (most use nano-SIM)
• Decide if you need a phone number (if yes, choose Mobal or similar)
• Estimate your data needs (1-3GB for short trips, 5-10GB for longer stays)
• Decide whether to buy online in advance or at the airport

On arrival:

• Have your passport ready (required for all purchases)
• Visit a SIM counter at the airport, BIC Camera, or Yodobashi
• Choose your plan and pay
