First of all, you will need to decide which of the following groups you belong to:
- I am a recovering mobile device addict and I want to be able to use the internet only for emergencies
- I am not good with directions and will need the internet particularly when navigating the subway or on the streets
- Internet is everything. If I could do a virtual tour of Japan I would have done so.
Now read the appropriate sections.

You could use any of the solutions in the next section, or you could head to the nearest internet / manga cafe to reply to an important business email. Keywords to look out for on the signboards are ネットカフェ (Net Cafe), インターネット (Internet), 漫画喫茶 (Manga-kissa or manga cafe). Most hotels and AirBnB accommodations also provide free internet services so do check if yours provide those.

You have a few solutions.
- During emergencies you could look for the nearest Starbucks and use this guide to get free WiFi access.
- Tokyo Metro stations also have free WiFi access (Toei Subway too) and there is bound to be a subway station within walking distance from where you are.
- JAL passenger can also get 14 days free Wi-Fi using these instructions.
- Convenience stores such as Lawson, FamilyMart and 7-eleven also have free Wi-Fi services (Lawson is the only one with English instructions).
