Business Idea: E-SIM for Tourists in Japan

Have you ever traveled to another country and had trouble finding Wi-Fi? You want to check Google Maps, message your family, or post on Instagram, but there’s no internet. I had this experience myself, and that’s when I thought of a new business idea: E-SIM for tourists visiting Japan.

My business idea is to provide E-SIMs for tourists coming to Japan. An E-SIM is a digital SIM card that you can download to your smartphone. There is no need to visit a store or wait in line at the airport. Just scan a QR code, and you’re online in minutes.

This service is perfect for travelers who want fast, simple, and affordable internet during their trip.

I thought of this idea because I have seen many tourists in Japan struggling to find Wi-Fi or buy a SIM card. Some get confused at the airport, and others can’t read Japanese instructions. I wanted to create something that helps travelers connect to the internet easily and enjoy their trip without stress.

Also, I noticed that many modern phones now support E-SIM, but not many services in Japan offer it in a simple way for tourists. I want to fill that gap.

How does it work?

1. The customer visits the website before their trip.

2. They choose the E-SIM plan: for example, 3 days, 7 days, or 30 days.

3. After payment, they receive a QR code by email.

4. When they land in Japan, they scan the code, and the internet starts working.

I will also provide clear setup instructions in English, Chinese, Korean, and other languages. If they need help, there will be customer support by chat or email.

Who is it for?

This service is for anyone visiting Japan—tourists, short-term students, or business travelers. It’s especially good for people who:

• Want to use Google Maps, Translate, or social media

• Don’t want to rent a portable Wi-Fi

• Have a phone that supports E-SIM

• Want to set up internet before arriving in Japan

Many SIM services in Japan still use physical SIM cards or rental Wi-Fi devices. The service is fully digital, easy to use, and eco-friendly. No waiting, no return, and no extra devices to carry.

Also, the website and support will be made for international users, with simple design and multi-language help.

Summary

My goal is to help tourists enjoy Japan without worrying about internet problems. With this E-SIM service, they can feel safe, connected, and ready to explore from the moment they land. The setup is fast, the plans are simple, and the experience is smooth.

In the future, I hope to grow the service and offer more travel tools to make visiting Japan easier for everyone.

A Wonderful Day at Centennial Beach

If you have a chance to visit Barrie in Ontario, Centennial Beach would be a must-see place. It’s located on Kempenfelt Bay, which is part of Lake Simcoe. The beach has soft sand and calm water, making it a great place to relax, swim, or just enjoy the view. In the summer, there are lifeguards on duty, so it's safe for everyone, including kids.

Around the beach, there are many things to do. You can play volleyball, basketball, or use the playground. There are also walking trails along the water, picnic tables, and barbecue areas. It’s a good place to spend the whole day with friends or family. The beach is clean and well-maintained, and there are public washrooms nearby, which is very helpful.

It's easy to get there. You can drive there and park nearby, or take a walk or ride your bike. In the summer, you can also rent E-bikes to explore the area. The beach is right near downtown Barrie, so there are shops and restaurants close by too.

One special season to visit is in August, during a big event called Kempenfest. It’s a popular arts and music festival with food, crafts, and live shows. Part of the event also includes a swim across the bay that starts at the beach. It’s a fun and exciting time, and the area is full of energy and people enjoying themselves.

What I like most about Centennial Beach is that it has a mix of fun and peace. You can play and be active, but also sit quietly and watch the water or the sunset. It’s a beautiful place that brings people together and shows the best of summer in Ontario. If you haven’t been there yet, I highly recommend visiting. It’s a simple but special place to enjoy nature and relax.

Introducing Myself

Hi everyone! My name is Taichi Kobayashi, and I am excited to join Tenatch as a new intern. I am from Japan and currently studying cybersecurity at Georgian College in Canada. Before that, I spent time studying and working in Japan. I have over five years of experience working in IT infrastructure and two years in web development, where I handled everything from setting up Linux and Windows servers to managing networks, databases, and automation tools. During that time, I developed strong skills in troubleshooting, scripting, and system security.

This is my first time working at a start-up, and I really appreciate the chance to learn and grow in this environment. I have a strong interest in cybersecurity, web development and AI. I am learning advanced skills in areas like network defense, cloud security, and penetration testing. I have also taken part in hands-on training at Rogers Cybersecure Catalyst, where I practiced real-world attack and defense scenarios like privilege escalation and Kerberoasting.

In the future, I hope to work remotely as a digital nomad while traveling and experiencing different cultures. I believe that this internship would be the key to pursue my IT career.

Outside of school and work, I enjoy watching the TV drama Suits in my spare time. I find the characters and legal stories really interesting, and it also helps me improve my English listening skills. This drama was set in New York and Toronto, which is also why I came to Canada. I also like traveling and exploring new places whenever I have the chance.

I am looking forward to working with everyone and learning together during this internship!
