7 days of unlimited data in Japan costs S$33.59 — about S$4.80 a day on NTT Docomo, KDDI (au) or SoftBank, with no roaming charge and no SIM to swap. In Japan, 5G is live and median mobile download speed is 55.2 Mbps.
Choose a Japan eSIM by matching the allowance to your trip length and expected use, then check the existing network table for phone compatibility. The page keeps its country-specific operator, band and median-speed information, while the sections below help you compare plan sizes and use official coverage information for the places on your itinerary.
Start with the length of your stay, then allow for navigation, messaging, streaming and work use. A fixed-volume plan gives you one data pool across its stated validity period.
Best for: A short city visit where mobile data is mainly for maps, messages and occasional browsing.
This is the smallest fixed-volume profile for a stay of up to seven days.
Usage tip: Use Wi-Fi for video, photo backups and app updates to keep more data available while exploring.
Best for: Trips of up to two weeks with regular navigation, messaging and light social-media use.
The 3 GB allowance remains available across the stated fifteen-day validity period.
Usage tip: Download maps before rail journeys and use mobile data for live directions and updates.
Best for: Longer stays or travellers planning regular streaming, video calls or work-app use.
A larger thirty-day data pool gives heavier activities more room than the short-trip profiles.
Usage tip: Compare your normal phone usage with the available allowances and monitor usage during the trip.

Subway and underground rail tunnels in Tokyo and Osaka have near-universal LTE/5G coverage, but mountainous rural areas in central Honshu and Hokkaido have significant coverage gaps. Band 11 (1500 MHz) and Band 18/26 (800/850 MHz) are Japan-specific LTE bands often absent from foreign phones, limiting rural and indoor coverage for roaming devices.
Official operator coverage information can be used to check 5G and LTE service by location. NTT Docomo's map includes prefecture-level lookup plus separate information for mountain trails and subways; use the map that matches the selected product's network details.
Check the neighbourhood around each hotel and the stations you expect to use. Official operator information can also identify service areas at stations, airports and other locations.
Use the separate mountain and route information where available, and check the destination as well as the journey. Compare your phone with the lower-frequency bands in the existing network table.
Check island and regional itineraries location by location. For travel beyond Japan, compare a matching country plan with a regional option and confirm every included country before departure.
Compare your phone with the 4G and 5G bands in the existing Japan network table. The published network notes highlight B11 and B18 or B26 as bands that can matter for some Japanese networks, alongside the other frequencies listed on the page.
Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.

From the neon-lit energy of Tokyo's Shinjuku to the serene bamboo paths of Kyoto's Arashiyama, Japan rewards slow, thoughtful exploration. Whether you are navigating a major city or a rural onsen town, a few tools make everything smoother.
With Google Maps and a local SIM or pocket Wi-Fi, you can find train timetables and walking routes instantly. Japan's public transport is punctual and extensive, but cash remains king at smaller shops, temples, and restaurants. Carry a reasonable amount of yen at all times.
For connectivity, a reliable SIM card or eSIM from a provider such as TPG Mobile ensures you stay online without hunting for Wi-Fi. Download offline maps as a backup. Learning basic phrases like sumimasen (excuse me) and arigatou gozaimasu (thank you) opens doors, and bowing slightly when greeting is always appreciated.
Japan's mix of ancient World Heritage sites and hyper-modern districts can feel overwhelming. These five attractions offer a balanced introduction:
These sites are well connected by rail. Book tickets for popular spots in advance during peak seasons.
Japanese cuisine is extraordinarily diverse, from street-stall snacks to multi-course kaiseki. Every region has its own speciality, but these six dishes form a solid introduction:
Eating out is safe and easy. Tipping is not customary and can cause confusion.
Spring (March to May) and autumn (October to November) are the most popular seasons for good reason. Spring brings Japan's famous cherry blossoms, with peak bloom typically in late March to early April. Key viewing spots include Kyoto's Maruyama Park and Tokyo's Ueno Park. Crowds are heavy, so book accommodation and train tickets months ahead.
Autumn offers cooler temperatures and spectacular red-and-gold foliage. October through November is prime leaf-peeping time, especially in Nikko, Kyoto's Eikan-do, and Hokkaido's Daisetsuzan. The weather is generally mild and pleasant.
Summer (June to August) can be hot and humid, with June's rainy season often dampening outdoor plans. However, this is also the season for lively festivals, fireworks displays, and climbing Mount Fuji (July to early September).
Winter (December to February) is cold but excellent for onsen hopping, skiing in Hokkaido or Nagano, and seeing fewer tourists at major sights.
Get these five items right, and your trip will be far more comfortable:
A travel eSIM means you can activate data coverage on arrival without queuing at airport counters. A power bank is also useful, as charging points in cafes are rare.
