"This is my first time to use eSIM. I am impressed by the ease of setting up. The speed is awesome. I got stable 5G in the city and reached 300 MBs easily. I cannot do many Speedtest because of the daily cap. I definitely will buy the same esim again for next trip."

Which is Better in Japan? eSIM,SIM card or Wi-Fi routers?

SIM cards offer the convenience of no need to worry about charging like Wi-Fi routers, and they take up very little space in your luggage. There are plenty of plans to choose from, but they do come with drawbacks such as a complex setup process and the requirement for a SIM-free smartphone.

Wi-Fi routers are easy to set up once you arrive and can be shared with multiple people or devices. However, they can require extra charging and the hassle of managing and handing over the device. eSIM, on the other hand, doesn't need a physical card, so there's no risk of loss or damage. The setup is relatively simple, but it’s only available on compatible smartphones.

Below is a table that compares the features and considerations of the three options.

FeatureWarning
eSIMNo risk of loss or damage; No need to carry around; Easy to set up; Can be used upon arrivalPhone number may not be used; Limited number of smartphones can be used
SIM cardNot bulky; Many purchase plans availableNeed pin to swap cards
Wi-Fi routerCan be used immediately upon arrival; Can be shared by many people; Can be connected to many devicesCan be troublesome to carry around; Difficult in receiving and delivering

Conclusion

eSIM offers unmatched convenience and flexibility for travelers with compatible phones, making it a top choice for tech enthusiasts or those seeking a hassle-free setup without the need to swap SIM cards.
SIM cards are a budget-friendly option for short trips, suitable for those who don’t mind physically replacing their SIM and managing limited data plans.
Wi-Fi routers are ideal for families, groups, or heavy data users who need to connect multiple devices. However, they come with the added cost and inconvenience of carrying an extra device.

You can choose the most suitable option based on your real needs.

This is the hotel I always stay at whenever I visit Tokyo, and it never disappoints. The location is fantastic. Since the Prince Hotel is right across the street, there are plenty of excellent restaurants and dining options nearby, which is a huge plus. Transportation is also incredibly convenient. Moving to major districts like Shinjuku, Ginza, and Shibuya by train/subway is fast and easy. If you are looking for a central base in Tokyo with great food and accessibility, I highly recommend staying here.

This room size is just right for one person without luggage. I'm not sure what tier it falls into in Japan, but in China, it's probably on par with or slightly below a Hilton. I'd be willing to stay here again on my next trip to Tokyo. There's a Kyushu ramen place nearby that's quite good, but I wouldn't really recommend Yuzugumi (Oil Group).

Ginza/Tsukiji Tokyo|0.66km from city center
Stepping into the lobby of the Imperial Hotel Tokyo, which opened in 1890, I was immediately captivated by the century-old elegance – it truly lives up to its reputation as Japan's 'state guesthouse' 💫. Located in the heart of Chiyoda Ward, it's just a 3-minute walk from Hibiya Station, and a 5-minute stroll to Ginza's famous shopping street. With direct views of the Imperial Palace and the lush greenery of Hibiya Park, it perfectly combines convenience and tranquility in central Tokyo. The rooms blend classic and modern styles. The custom SleepWorks mattress offers just the right firmness, and the MIKIMOTO saltwater pearl-infused bath amenities add a touch of exclusive luxury. Some rooms even offer direct views of the Imperial Palace, allowing you to wake up to the morning sun streaming through the windows – a truly atmospheric experience. What impressed me most was the meticulous service: bellhops keep loose change handy for currency exchange, the laundry service has even earned praise from Hollywood stars, and the attentive guidance from kimono-clad attendants – every detail embodies the essence of Japanese *omotenashi*. With 17 distinctive restaurants, there's something for everyone. The French cuisine is exquisite and refined, while the Japanese dishes are incredibly fresh and soulful. The Old Imperial Bar's whiskey selection is a favorite among politicians and business elites. The 21st-floor heated pool and high-end fitness center offer city views while you exercise. In this century-old hotel, which subtly incorporates Frank Lloyd Wright's architectural aesthetics, enjoying a custom meal and a classic cocktail made me truly understand that Tokyo's high-end escapes have always been hidden within these time-honored treasures.

Ginza/Tsukiji Tokyo|0.18km from city center
The location is fantastic! It's less than 100 meters from Kyushu Ramen, and Yu-gumi (a popular bathhouse) is also nearby. There's a great yakiniku (grilled meat) restaurant next door with excellent quality meat. You're surrounded by food options, and Don Quijote and Lawson are also very close. It's super convenient to drop off your shopping bags at the hotel after a stroll in Ginza, or just head back for a quick rest if you're tired. Getting to other places is a breeze too, as the subway station entrance is right downstairs. The bed is large, and the bathroom and shower are separate, both quite spacious. For one person, the room size feels just right, but it might be a bit snug for two people or if you have two large suitcases.

Tokyo Tower Area Tokyo|2.04km from city center
Our overall experience at the hotel was excellent. They tried their best to accommodate all our requests before check-in, such as a quiet, non-smoking room near the elevator. As soon as we got out of the car, staff came to help with our luggage and took it directly to our room. For all 8 days of our stay, the room was cleaned impeccably every day. The view of Tokyo Bay from the window was stunning. What truly stood out was how seriously and incredibly quickly the customer service team responded to our calls for deliveries, always completing our requests promptly.

Right across from a side entrance of Ginza Six, with plenty of great food options nearby. It's a short 3-5 minute walk to the subway station, and if you head towards Shimbashi for less than ten minutes, there's a Don Quijote. The room is small, but it's perfectly adequate for one person and you can still open your luggage.

Ginza/Tsukiji Tokyo|0.89km from city center
This hotel is super easy to find! Just take exit 3a, turn right, walk straight down the alley, then turn right at the traffic light. It's the second building. The triple room was a bit cramped for opening our luggage, but everything else was great. It was quiet, perfect for relaxing. There are four convenience stores nearby (two Family Marts across the street from the subway, and a Lawson on the same block). They even provide disposable toiletries, which you can grab from a shelf next to the front desk. For nearly 1000 MYR a night for a triple room, the breakfast was a letdown, especially for a Malaysian like me. All they had was plain congee. I ended up buying bread from the convenience store. My kids ate plain rice with seaweed soup. No sunny-side-up eggs, not even the most basic options, so the breakfast definitely isn't worth it.

The hotel was conveniently located near both main stations so it made transportation very easy to find. The staff were very polite. We even participated in an origami free class that happens every Tuesday in the lobby which was a lot of fun. They had Starbucks coffee machine that wasn’t too bad in the lobby to get that quick drink. The only down side was the shuttle service to hotel. We had to pay and go to a nearby hotel to ride it but other than that it is a very good experience and would stay there again for sure.

I stayed at the Tokyo Dome Hotel from January 31st to February 3rd, 2026. The hotel's location is excellent, right next to Tokyo Dome, and it's just a 3-5 minute walk to either the subway or JR station. The lobby is spacious, and check-in and check-out are handled conveniently via self-service machines. Compared to other hotels in Japan, the rooms here are quite roomy and bright. We booked a twin room, and it was a very generous 33 square meters. The hotel features transparent glass observation elevators, offering views of the Tokyo Skytree. Do note that room prices at this hotel fluctuate significantly based on events at Tokyo Dome, with rates potentially doubling or more.

Tokyo Tower Area Tokyo|2.41km from city center
It's a pity I forgot to take photos, but the hotel's location is undoubtedly excellent. I booked it because I saw that the hotel was renovated in 2025. I'm not sure about other rooms, but I was a bit disappointed with the connecting room I booked. The hotel's ambiance is great; I think the renovation mainly focused on the lobby and other public areas, which look very new. However, inside the room, it felt like only the wallpaper had been changed. You could still smell an old damp odor, and the lighting was quite dim. While connecting rooms are convenient for staying with parents, and the bathroom seemed newly renovated, the beds, carpets, and curtains really gave off an 80s guesthouse vibe. So, the room itself was a bit disappointing, but the exterior was fine. As for service, I found it somewhat mediocre. The hotel has quite a few Chinese staff. Honestly, I don't know how they treat foreign guests, but for Chinese guests, it was pretty average. Basic polite greetings felt perfunctory, and service speed was quite slow. The Sky Bar upstairs is nice. If you want a window seat with a panoramic view of Tokyo Tower, you need to book in advance or wait for about half an hour. It was quite late, so I didn't want to wait and sat in a booth further back. Do note that there's a seating charge for those booth seats. The view from the window is indeed fantastic, you can see the entire tower. Breakfast was also decent, and you could see Mount Fuji in the distance from the breakfast room.
