Do I Need a Japan Travel SIM Card?

What is a Japan travel SIM card, and why would you need one? For those of you that travel around the world with an unlocked phone, you’re probably used to picking up a SIM card soon after landing. Japan is no different, right? Well, kind of…

What is a Travel, or Tourist, SIM Card?

A travel SIM card, or tourist SIM card, is a pre-paid data card for short-term visitors to Japan. They offer pretty fast speeds, and a variety of data limits. Prices are based mostly on how much data you need.

The cards can be easily recharged, or even replaced, once the data limit is reached. Most companies have an online gateway to allow you to recharge your SIM.

The one thing that sets Japan apart from other places I’ve been, is that the SIM cards are for data only. Texting and voice calls are usually not available on tourist SIM cards.

Why do I Need a Travel SIM Card?

If you’re an avid reader of our blog, or subscribe to our YouTube channel, you already know what I’m about to say. Free Wi-Fi hot spots in Japan are slow and spotty. They have limited usage time, and you’ve got to re-register every time you want to use the hot spot.

The easiest, most reliable, and keep you sane solution is to have your own internet connection. This can be done with either a SIM card for your unlocked mobile phone, or by renting a pocket WiFi router.

I know that some mobile phone carriers provide international data, voice, and text. In my experience this option is usually not very fast, or it’s really expensive. Pre-paid SIM cards and pocket Wi-Fi rentals are a much more sensible answer.

6 Best Travel SIM Cards

Honestly, there is no best SIM card in Japan. Just about all of them use the same networks, NTT Dococmo or Softbank, and they all come with similar data structures.

The main deciding factor will be your wallet and your needs. Below you’ll find a list, in no particular order, of some of the biggest players in the SIM card industry.

1. Sakura Mobile

Sakura Mobile is one of my favorite SIM card providers. They’ve been around since 2014 and are one of Japan’s major players in the tourist SIM card industry. They’re reliable, have outstanding customer service, and thousands of satisfied clients.

Although a bit more expensive than most, these SIM cards are a great option if you’re in a pinch or if you forgot to order your card online in advance.

Final Thoughts

I recommend ordering your SIM cards in advance, and have them delivered to your home. That way you can get connected the minute you land. It’s not unheard of for the airport kiosks to sell out of SIM cards and pocket Wi-Fi routers.

Getting it online and having it ready when you arrive will save you from unnecessary frustrations. Remember, the early bird gets the worm.

One more thing. Unless you speak Japanese, or are doing business in Japan, there isn’t much need for having the ability to make phone calls.

If you’re traveling with a group, it’s best if everyone gets a data SIM and then use an app like WhatsApp to text and call each other. It’s cheaper upfront and you won’t rack up a huge bill talking, texting, and sending pictures.

If you need to call and make a reservation, it’s best to have your hotel concierge do it for you. Odds are the person on the other end will only speak Japanese.
