Summer is the time when Japan holds a series of attractive traditional festivals such as Omatsuri or spectacular fireworks displays. However, this passionate atmosphere also comes with a big challenge: tens of thousands of people flock to the same area. Losing your companion or not being able to look up directions is a problem that can easily happen if you do not have a stable internet connection.
Summer festivals in Japan often take place around temple areas, river banks or main streets. When tens of thousands of people gather in a narrow space, moving in groups becomes difficult. If you carelessly look away for just one minute, you can lose your companion.
In that situation, regular calls over international mobile networks can be very expensive, and public Wi-Fi in festival areas is often overloaded or unavailable. Owning a private network solution on your phone helps you text, make voice calls via the app and share your location instantly.
To avoid interruption in communication, choosing the appropriate data capacity is very important. Normally, basic needs when traveling include looking up maps, finding train routes, sending messages and sharing a few photos on social networks.
The estimated capacity of about 1GB per day is enough to meet these basic tasks. If you have a habit of watching short videos or live streaming festival atmosphere, you should consider higher capacity options to avoid running out of data midway.
Currently, travelers have two popular options: physical SIM and eSIM. With a physical SIM, you receive it by mail before your departure date. Meanwhile, eSIM brings convenience by receiving an activation QR code via email immediately after completing payment.
Using eSIM helps you run two SIMs in parallel on the same device. You still keep your Vietnamese SIM to receive important calls or OTP codes from the bank, and use the eSIM data to access the network in Japan. When paying via VietQR transfer in VND, you can also more easily manage costs.
Before deciding, check if your device supports eSIM. Compatible devices are usually iPhone XR, XS or higher or most high-end Android models manufactured since 2019.
To proactively prepare, you can refer to see Japanese eSIM plans to choose the right capacity for your schedule.
Mobile phones that operate continuously to navigate and search for information will consume battery faster than usual, especially in crowded places when the device has to constantly search for a signal. Equipping a backup battery with sufficient capacity is essential.
Besides, you need to pay attention to the electrical plug standard in Japan. This country uses standard Type A sockets (two flat pins) with a voltage of 100V. Have the appropriate adapter ready so you can fully charge your devices at the end of the day.
Before joining the crowd at the festival, agree with your travel companions on a fixed meeting point, such as the gate of a specific train station or an easily recognizable convenience store. If unfortunately contact is lost, everyone can proactively move to this meeting point.
When you have an internet connection, use the direct location sharing feature on messaging apps. This makes it easy to see each other's direction of movement in real time without having to bother describing the location.
Tip: You should take a screenshot of the map of the festival area and the meeting point before moving into a crowded area, in case the network signal is locally congested.
In order to experience a complete and secure Japanese summer festival, preparing a reliable network connection method is an indispensable step. You can refer to solutions from shibaSIM with a thoughtful Vietnamese support team and a refund policy if activation cannot be due to a service package error.

Japan will officially convert the Tax-free tax refund mechanism from tax-free at stores to tax refund at border gates from November 1, 2026. Vietnamese tourists need to carefully learn about the new process to be proactive about their budget and time when traveling.
