Trip.com Japan eSIM offers a range of cheap and fast data plans ideal for those visiting Japan. These plans provide reliable connections across the country, including all major cities like Tokyo, Osaka, and Kyoto. Each plan is priced very cheap (I've compared with other eSIM providers, Trip.com is the cheapest) and designed to meet different travel requirements, with guaranteed nice customer service throughout Japan. You can choose from a variety of 1-day plans, including 500MB, 1GB, 2GB, or even unlimited high-speed data, making it a very flexible and affordable option.

When you choose any of Trip.com's Japan eSIM packages, which vary from daily high-speed data to extensive monthly plans, you receive a QR code quickly. This makes the setup process fast and easy, helping you get connected in just a few minutes—perfect for activating your eSIM while you wait for your luggage at the airport.

The Japan eSIM plans vary in duration from one day up to 30 days, with data allowances ranging from 500MB to unlimited. Pricing starts at just $0.93 for a one-day 500MB plan and goes up to $44.64 for a 30-day unlimited data plan, providing affordable options for every traveler. Running on a strong 4G LTE network, the eSIM ensures reliable internet everywhere in Japan, making it great for map, games and videos without interruptions. My experience with Trip.com's Japan eSIM has been very positive, with good customer support, easy installation, and fast speeds without any delays in Tokyo and Osaka. I highly recommend this choice.

Nomad Japan eSIM 1 Day

500MB1 Day$2.50

Nomad is a popular eSIM provider available in over 100 countries. However, my experience with Nomad has been quite negative. Despite its widespread use, I found it to be the most expensive provider I've encountered, with slow internet speeds and poor customer service. If you have a lot of money and want a subpar internet experience in Japan, you might consider Nomad.

Nomad's eSIM plans range from 1GB to 100GB, with no unlimited data options. This means that once you run out of data, you'll need to top up and pay again. While some plans are advertised for less than 5€, these come with a 1GB limit, necessitating frequent recharges. Additionally, their customer service is only available in English and can be accessed through a form on their app or website, requiring a purchase ID code. On the plus side, Nomad eSIMs allow data sharing across devices, but this can quickly deplete your data.

Purchasing and installing a Nomad eSIM is straightforward and can be done through their app, available on both iOS and Android. However, you should check if your device is compatible before buying. While Nomad offers various regional, country, and global data packages and has eSIMs for 112 countries, their plans have significant limitations. Data plans are limited to 7 or 30 days, and they do not include calls or SMS. Despite these drawbacks, the brand remains popular due to its broad availability and easy installation process.

EZsim Japan eSIM 1 Day

500MB1 Day$1.30

EZsim is another option for a Japan eSIM one day plan. It is slightly more expensive than Trip.com, offering only 500MB or 1GB data plans for one day. Personally, I find these limits too restrictive for my needs when traveling. While EZsim is still affordable, the limited data makes it less appealing for those who need more connectivity.

Trip.com, on the other hand, offers more varied and cheaper options, including an unlimited plan that eases my worries about running out of data while abroad. Trip.com's unlimited high speed 1 Day plan provides better value and peace of mind. If you need less than 1GB and don't mind paying more, you can choose EZsim, but for better flexibility and cost, I recommend Trip.com.

Not sure how much data you need for one day? Check the data consumption average table below:

How Much Data I Need for 1 Day Japan eSIM?

When considering a Japan eSIM one day plan, it's crucial to choose a plan that fits your usage. For instance, if you frequently use data-heavy apps like TikTok or Netflix, a higher data allowance or unlimited plan would be more suitable. Trip.com offers a variety of plans, including an unlimited data option, which can help alleviate the anxiety of running out of data during your travels.

For light data usage, such as using Google Maps or social media, Trip.com also provides excellent options that are still the cheapest. Personally, I need about 2GB of data per day because I enjoy watching YouTube while waiting in lines or on the subway. Trip.com's 2GB/day plan is perfect for my needs. If you're unsure about your data needs, refer to the data consumption table below to make an informed decision:

PlatformData Consumption per Hour
Instagram0.12 GB – 0.18 GB
Google Maps5 MB – 10 MB
Facebook0.12 GB – 0.18 GB
Twitter0.06 GB
TikTok0.84 GB (default settings)
Netflix0.3 GB – 7 GB
YouTube0.14 GB – 1.7 GB
Apple Music0.04 GB – 0.15 GB

These figures give a general idea of how much data each app consumes. For instance, using TikTok for an hour can consume up to 840 MB with default settings, while streaming high-quality videos on YouTube or Netflix can use significantly more data. Apps like Google Maps are much lighter on data, using only 5 to 10 MB per hour in standard mode.
