Here we will introduce some apps that are essential for life in Japan, but you will need to register or log in to these apps using a Japanese phone number.
Payment scene
Electronic payments have become a part of everyday life in Japan, and many people no longer need to carry cash. A particularly popular payment app in Japan is PayPay. To use PayPay, you need a Japanese phone number, and in addition to making regular payments, you can also request splitting bills with friends and pay utility bills. It's very convenient because you get points for every payment.
Scenes from everyday life
Using apps for daily life services can make your daily life more convenient, but you need a Japanese phone number to use these apps.

Emergency contact methods in the event of a disaster
In the event of an emergency in Japan, you can ensure your safety by quickly contacting services such as the police, fire department, and ambulances.
However, when a disaster occurs, the demand for safety confirmation increases sharply, putting a strain on the communication system and making it difficult to use general means of communication. In preparation for such situations, the " 171 Disaster Message Dial " has been set up and is mainly used for reporting and confirming the safety of others.
This service allows people in disaster areas to record messages to let others know they are safe, and then family and friends can play those messages to confirm their safety, making it easier to quickly confirm their safety.
Steps to record a message:
1. Dial 171.
2. Follow the instructions and press 1.
3. If you are in the disaster area, dial the area code for your home or contact number. If you are not in the disaster area, dial the area code for the phone number in the disaster area you want to contact.
4. Record your message within 30 seconds.

How do I get a SIM card in Japan?
So far, we have looked at situations where you need a Japanese phone number, but do you know how to get a SIM card? There are various options for purchasing a SIM card, each with its own characteristics.
Here we will introduce three ways to purchase SIM cards to enable convenient and smooth use of communication services.
