If the Free Wi-Fi in Ota City Doesn’t Work…

As you can see, Tokyo’s Ota Ward offers free Wi-Fi that anyone can use 24 hours a day, free of charge.

By connecting to the free Wi-Fi, you can immediately check tourist attractions in Ota Ward, look up information on stores, and even check information on train and bus delays, making it very convenient.

However, while it is convenient, if too many people connect to the Ota City Free Wi-Fi at once, the connection may suddenly cut out or the speed may slow down.

Also, because anyone can connect, security is weak, so there is a good chance that your personal information could be stolen without you realizing it.

If you are a frequent user or spend a lot of time on the Internet, consider using pocket Wi-Fi or an eSIM, which can be used immediately after registration.
