Japan Sim Card: Hit the Ground Connected

It isn’t easy to get started in Japan, and it’s almost impossible unless you’re online.

Real Estate Japan has teamed up with IIJ Japan Travel SIM to offer you a convenient and inexpensive way to get data service almost as soon as you arrive.

1 What is the Japan SIM Card?

The IIJ Japan Travel SIM is a re-chargeable 2GB Sim card that you can simply insert into your mobile device to get data coverage anywhere in the country.

On compatible mobile devices, the card offers high speed service (LTE/3G).

Buy the 2GB IIJ Japan Sim Card from Real Estate Japan at a great price: 3,500 yen (including tax).

The Japan Travel SIM card allows you to get connected immediately after you plug in and set up your device. You won’t need to wait a day for the card to be activated, which is the case with many cards.

IIJ Sim Card Overview

2 Who is the IIJ Japan SIM Card meant for?

The 2GB Japan SIM Card is ideal for people who need a convenient and inexpensive way to get data service on their mobile devices.

For example, if you are just arriving in Japan and need a way to get online so that you can email or Skype your family or contact the Bilingual Brokerage Assistance team here at Realestate.co.jp to get your apartment lease signed, this SIM card may be right for you.

Instructions for using the card are in English. Phone support is also available in Japanese, English, and Chinese from 9am to 7pm 365 days a year  through the Japan SIM Card support center.

Please note that phone service is not included with the Japan SIM Card. This SIM card will only work with an unlocked cell phone.

The 2GB card is available for purchase, in cash and in-person only, at Real Estate Japan’s office, located nearby Akabanebashi Station (on the Oedo subway line) and Azabujuban Station (on the Nanboku subway line) in Minato ward, Tokyo.

4 How much does it cost?

The card is available for purchase, in cash and in-person only, at Real Estate Japan’s office.

Please be aware that purchases are final and non-refundable, and once again please make sure that your cell phone is unlocked to use this service.

5 Exactly how much is 2GB of data? How much data can I actually use and access?

As a rough guideline, with a 1GB card, our partners at IIJ Japan Sim tell us that you can access approximately the following:

  • Access the top page of a typical mobile news site about 3,410 times
  • Send a 300-character text message about 204,800 times
  • Use Google Maps on an Andriod device about 280 times
  • Make a 3-minute Skype call about 580 times (about 1,470 minutes of Skype call time)

Real Estate Japan is offering the 2GB card, so you would be getting about twice the amount of data as in the examples above.
