”Traveling to Japan”　How to use the internet in Japan: Introducing VOYAGEE’s eSIM.

In recent years, the number of foreign visitors to Japan has been steadily increasing year by year.Many travelers will have wonderful experiences by immersing themselves in Japanese culture and food.

On the other hand, the current situation is that the acceptance environment within Japan is still not fully prepared.

Those planning to travel to Japan should use this article as a reference for their preparations in order to enjoy their trip to Japan more fully.

Things foreign visitors find inconvenient or frustrating in Japan

Traveling to Japan isn’t all fun and games. It’s natural to feel some inconveniences and frustrations when living in an unfamiliar place.

Among these, many complaints arise about the internet situation.

Especially, there are few places like restaurants, shrines, or on trains where free Wi-Fi is available.

For instance, having internet access is necessary to navigate Japan’s complicated railway system. With so many types of trains, in major cities like Tokyo and Osaka, the railway lines can feel like a maze.

You might wonder which platform to go to for your train to your destination or if you need to transfer trains along the way. Even Japanese travelers can get confused.

Also, while services and signs for foreigners are increasing at tourist spots in Japan, it’s not as common in rural areas.

Often, the guidance at Japanese tourist sites is only in Japanese. You might get some materials but not know what’s written in them. Audio explanations of exhibits play, but you might not understand what they’re saying.

In such cases, if you set up an environment where you can connect to the internet yourself, you won’t get lost while taking the train. You can enjoy your time at tourist spots more meaningfully.

Another thing is that I sometimes feel inconvenienced or frustrated when connecting to the internet.

It’s about the procedure for connecting to the internet in Japan. Many people seem to be dissatisfied with the process because free Wi-Fi connections require authentication or registration.

Even for Japanese people, the Japanese method that emphasizes security can feel cumbersome.

There may be a need to register personal information or email addresses.

It’s annoying to have to enter personal information every time you use free Wi-Fi, especially considering things like data leaks.

VOYAGEE’s eSIM is a prepaid type SIM card that can be used in Japan.

So, for those who are planning a trip to Japan but don’t know how to use the internet while there, I would like to introduce VOYAGEE’s eSIM.

The VOYAGEE eSIM is a prepaid SIM card that can be used in Japan. It becomes usable by installing it on your smartphone.

It is suitable for trips to Japan lasting about a month. If you plan to stay in Japan for a longer period, you may also consider options such as a Wi-Fi router or a WiMAX contract.

You can also install additional VOYAGEE eSIMs to use eSIM alone. However, please note that the longest duration for the eSIM sold by VOYAGEE for use in Japan is set to 20 days, so you will need to purchase and install a new eSIM every 20 days.

What is VOYAGEE’s eSIM?

VOYAGEE’s eSIM is not a traditional physical SIM card. It is a sustainable prepaid eSIM that can be purchased online, allowing for comfortable communication on your smartphone during your travels.

VOYAGEE eSIM is operated by T-Gaia Corporation, which is the largest mobile phone sales agency in Japan.

What is eSIM?

eSIM stands for embedded SIM, which means a built-in SIM card.

Devices that support eSIM can use communication services without a physical SIM card. You can easily set it up just by scanning a QR code with your camera.

Just don’t forget to check if your smartphone supports eSIM before using it.

VOYAGEE’s eSIM is way more convenient compared to rental Wi-Fi or regular SIM cards. Rental Wi-Fi and regular SIM cards take time to be received, and with rental Wi-Fi, you have to return it.

VOYAGEE’s eSIM doesn’t take time from purchase to reception. Once you buy it, you instantly get a QR code that you read to complete the setup. You’ll receive the QR code via email. Since you don’t need to swap SIM cards, you won’t have to worry about losing your main line’s SIM card. Plus, there’s no risk of running out of charge, losing, or breaking something like with Wi-Fi routers.

How to use VOYAGEE’s eSIM

First, choose the eSIM you want to purchase based on the number of days you’ll be traveling and the data capacity you’ll be using.

From my experience, it’s safer to get a bit more data capacity than you think you’ll need.

This is because there might be times when you can’t connect to the hotel’s free Wi-Fi or when the connection is slow. In those moments, if you’re using the eSIM to look up things for the next day, make plans, or just kill time, you’ll end up using more data than you expected.It’s important to have some extra data capacity so you won’t run out during your trip.

After purchasing the eSIM, you’ll receive an email from VOYAGEE.Once you scan the QR code displayed there, you can install it.

For the steps, check out the official site.

Since it’s a Japanese company’s site, it might be a bit tricky to navigate at first. You can only choose Japanese or English for the site’s language.

Still, if you’re interested, give the site a visit.

How to use the internet in Japan: A summary.

Japan sees a lot of travelers, but the reality is that the system to accept foreign visitors isn’t quite ready.

You might have noticed, but it’s going to take a long time to solve this issue. That’s why it’s frustrating to give up.

For travelers, the internet situation in Japan is terrible. That’s the conclusion you come to. If it’s no good, you just have to prepare. So, what’s needed for travel is a way to use the internet cheaply and easily.

You have the freedom to choose. It might take a bit of effort, but you can also sign up for a Wi-Fi router. If you’re looking for convenience, affordability, and speed, trying VOYAGEE’s eSIM could be a good option too.
