Chat on WhatsAppWhat is the best eSIM for Japan?
For a week in Japan with maps, messages and email, the 1 GB plan for 7 days (£3.29) is usually enough. With social media and video, expect to use 3 to 5 GB per week: the 5 GB plan for 30 days costs £10.59. For heavy use or work, unlimited plans start at £8.69 for 3 days.
Which networks does the Japan eSIM use?
The Japan eSIM works on the KDDI Au and Softbank networks, with up to 5G speeds where available.
The unlimited plan is regional: it works in 18 countries, including Japan, and its validity period starts when the eSIM connects to a network in any of them. On this plan, you get up to 4G LTE on KDDI Au and up to 5G on Softbank.
Does the Japan eSIM work in Tokyo, Osaka and Kyoto?
Yes. The eSIM works on the KDDI Au and Softbank networks, with up to 5G speeds where available. Fixed-data plans cover all of Japan, including Okinawa and Hokkaido.
Does the Japan eSIM come with a phone number?
No. Japan eSIM plans are data only. WhatsApp stays on your usual number, and you can keep your primary SIM in your phone.
How much data do I need for 15 days in Japan?
With maps, messages and email, expect to use about 1 GB per week: the 2 GB plan for 15 days costs £5.79. With social media and video, it's more like 3 to 5 GB per week: the 10 GB plan for 30 days costs £16.99. If you'd rather not track your usage, 15 days of unlimited data costs £36.69.
eSIM, local SIM or roaming: which is best for Japan?

For Japan, plans start at £3.09, and 30 days of unlimited data costs £54.79 (£1.83 per day). With roaming, you pay whatever your network charges; with the eSIM, you know the price before you travel.
Can I top up without switching eSIMs?
On most plans, yes: you top up the same eSIM from your account or the Wavee app, with no new QR code and nothing to install. The top-up screen shows the plans that work with your eSIM.
Can I use my phone as a hotspot?
Usually yes, but it depends on the plan and the local network. If it matters for your trip, talk to us before you buy.
What if I can't use the eSIM?
You have up to 30 days to request a refund in eligible cases: a cancelled trip, an incompatible or locked phone, or an eSIM that doesn't connect. We review every request, and our support team will first try to fix the problem with you on WhatsApp or by email.
