Mobile data in Kyoto

The city itself asks nothing of you

Kyoto is dense, flat in the middle, and very well covered. Gion, Higashiyama, Nishiki Market, Nijo Castle, Kinkaku-ji, the station area and the main central streets all have strong signal on every carrier, with 5G through the centre and the main tourist spine, and 4G averaging around 42 Mbps.

So for the ordinary Kyoto trip — temples, a machiya guesthouse, day trips on the JR lines — nothing on this page will change what you buy. Whatever plan covers your Japan itinerary covers Kyoto. The rest of this page is about two specific places where that stops being true, and about a piece of advice you will see elsewhere that we think is wrong.

Fushimi Inari, above the first thousand gates

The part of Fushimi Inari that appears in photographs is the lower section near the main shrine, and it has strong signal. Most visitors walk twenty minutes up, take their pictures and come back down, and for them this is a non-issue.

The full trail is different. It climbs Inari-san and takes three to four hours to loop, and plenty of people do it at night, when the gates are lit and empty. Signal weakens above roughly the mid-mountain point, and in the deep forest sections near the top it drops out on some networks entirely. That is a safety consideration rather than an inconvenience if you are up there alone after dark.

Arashiyama has a smaller version of the same thing. The bamboo grove has intermittent signal — a combination of the canopy and the local topography — but the grove is a short walk and everything around it, including Tenryu-ji and the riverside, is well covered. Nobody needs to plan around it.

Why we will not tell you to buy Docomo

The standard advice for the Fushimi Inari night hike is to get an eSIM that runs on NTT Docomo, which is generally reckoned to have the widest rural and mountain coverage of the Japanese networks. The first half of that is sound. The second half is not something you can act on.

No travel eSIM in our Japan data is sold as a Docomo product, and none of them names Docomo at all any more. eSIM Go's listing names SoftBank; Airalo, Saily, Nomad, Holafly and eSIMCard publish nothing. Holafly is the change: this page used to say its listing named NTT Docomo and SoftBank together, and reading its Japanese prices off its own site on 18 August 2026 showed it publishes no host carrier for Japan or for any country. The Docomo attribution was ours, not Holafly's, and it has gone. The one listing that remains has not been confirmed against eSIM Go by anyone here — it is a lead, not a fact.

So a recommendation to pay more for Docomo coverage on the mountain rests on something we cannot check. The thing that actually works is free: download Kyoto and the Fushimi Inari trail as offline maps before you start, and if you are doing the full loop at night, tell someone at your accommodation when you expect to be back.

What to buy

Airalo and Saily prices were read from their own sites on 13 August 2026 and Nomad's on 17 August 2026. An earlier version of this page said Japan's market stopped at 20GB with no 50GB tier; that was wrong. Nomad sells one, and it is the cheapest data in the country.

The 20GB row works out at $1.20 a gigabyte, which we used to call the cheapest rate in Japan. The 50GB row is $0.70. Note that "Moshi Moshi" is Airalo's retail name for its Japan product, not a network — it tells you nothing about coverage.

The pricing across providers at 10GB is tight enough that optimising it is not worth an evening. Our full country comparison is on the Japan hub.

Buying a SIM in Kyoto

A passport is required and scanned for any tourist SIM in Japan, so this is a counter transaction rather than something off a shelf. In Kyoto the usual answer is Bic Camera near Kyoto Station, which has English-speaking staff and sells SIM cards. Typical airport pricing in Japan is around $12.

If you arrive in Kyoto already without data, that is your in-city option. Otherwise there is no reason to wait: install before you fly.
