Quick summary
Our fare scan on 11 October 2026 found London—Tokyo round-trip economy from €577, with 40 fares running from €577 to €721. Thirty-nine of the 40 are one-stop and one is two-stop. No source supports the €400—€600 Chinese-carrier saving the previous version of this page quoted.
China’s 240-hour visa-free transit still turns a layover into a ten-day stopover for eligible passports, but the third-country ticket rule and the regional limits decide whether it works. Here is the fare picture, the rules, and the checks that settle the decision.
No source supports the €400—€600 saving the previous version of this page promised for routing Europe—Japan through a Chinese carrier. The carrier-by-carrier comparison is unsupported, and the fare samples behind it are gone.
The current London—Tokyo scan does not name an airline. It gives a market baseline, not evidence that a Chinese carrier is cheaper.
So the cheapest way to fly to Japan from Europe has changed shape. The question is whether a China-routed itinerary beats that baseline once your passport clears China’s transit list and your arrival port clears its regional limits.
What the current Europe—Japan fare picture actually shows
The scan’s 40 fares span €144 from bottom to top. The cheapest departs 1 December 2026 and returns 15 December. The dearest departs 17 April 2027 and returns 1 May. Everything else falls between those two prices.
Almost every itinerary is one-stop: thirty-nine connect once, while a single fare connects twice. That makes a single connection the norm in this sample, not a feature unique to a China routing.
No source we hold gives fares for both sides of the Chinese-versus-European carrier comparison. A similar reversal has already played out on the US—Japan corridor: a nonstop round trip priced below the best China routing, as the October report on US–Tokyo fares set out.
The lowest fare is one departure date, not a price you can book today. The next cheapest fares in the scan are €593 and €598.

How China’s 240-hour transit works for Japan
China’s transit exemption was updated on 21 August 2026 and covers passport holders from 57 nationalities. According to the National Immigration Administration, it allows a visa-free stay at designated entry ports nationwide.
The rule works only as transit.
You cannot use it to fly back to the country you started in. London—Shanghai—London fails; London—Shanghai—Tokyo passes. Foreign transit passengers complete an arrival card on arrival. Tourism, business, exchange visits and family visits are allowed; work, study and news reporting need prior approval and the appropriate visa.
Geography is the constraint most travelers miss. Entering through Beijing permits travel only within Beijing, Tianjin and Hebei. An arrival in Shanghai does not let you continue to Beijing, Chengdu or Xi’an on the same permit. The National Immigration Administration’s policy page carries the current port and nationality lists, and Shanghai’s municipal guidance sets out the same regional limits for its own ports.
The framework has widened twice. On 17 December 2024, the 240-hour rule expanded to allow travel across 24 provinces rather than a single port cluster. The 65-port network took effect on 4–5 November 2025.
The exemption is not specific to Japan. It applies to any long-haul itinerary that passes through China between two different countries, so the same eligibility test applies beyond trips to Tokyo.
When to book, and Japan’s new departure tax
Japan has tripled its international departure tax to ¥3,000, about USD 19, from mid-2026, according to Tokyo Tourism’s guidance updated on 19 August 2026.
The same guidance recommends booking long-haul Tokyo routes two to four months before departure. Its peak periods include cherry blossom in late March to mid-April, Golden Week, and the November foliage season. Booking three or more weeks ahead rather than at the last minute can save close to half on some routes.
The scan’s cheapest departure falls outside the windows Tokyo Tourism names. The sources measure different things: a live London—Tokyo sample and general booking advice.
The scan’s €577–€638 band sits €83 or more below its €721 top. That is the margin that survives the departure tax.
How to decide without the unsupported saving
Eligibility comes before price: the transit rules decide whether a China routing is available to you at all. If those conditions fail, the China route is not a cheaper option; it is a longer one.
A stopover also needs enough time to be useful. A connection that meets the transit rules can still leave no time to enjoy China.
A Tokyo-in, Osaka-out trip raises a different question. Open-jaw tickets into Tokyo and out of Osaka remove the return leg without adding flight cost.
What the transit rules mean for your trip
The decision starts with eligibility, then moves to the fare and the time available for a stopover. Those are separate tests.
Travelers with an eligible passport. If your nationality is on China’s 57-country list, price a China-routed itinerary against the €577 baseline our scan found on 11 October 2026. Check the arrival port against its permitted region before booking: Shanghai entry covers Shanghai, Jiangsu and Zhejiang only. Then confirm the onward ticket is to a third country, with a confirmed seat and date inside 240 hours. Less suited: travelers whose passport is not on the list, for whom the transit permit does not exist.
Travelers locked to peak dates. Tokyo Tourism advises avoiding late March to early April, Golden Week and the October–November foliage season, and recommends booking four to six months ahead for them. If your dates are fixed there, book early rather than waiting for a dip. Less suited: travelers who can move their trip to January–February, late May–early June or September, who should pick a date inside the cheaper window, then test the fare against the scan’s floor.
Travelers who want the stopover itself. The visa-free stay costs nothing in visa fees. Build a connection long enough to leave the airport and return, and remember the 240-hour clock starts at 00:00 the day after entry, not at landing. Less suited: travelers on a three-hour connection, who satisfy the transit rules but get the paperwork without the time to use it.
China’s eligible list last changed on 20 August 2026, when Kyrgyzstan and Vietnam were added. For a China-routed trip, check the current list before booking.

Questions? Answers.
Who can use China’s 240-hour transit rule?
Nationals of 57 countries who are transiting to a third country and hold a confirmed onward ticket with a reserved seat and date inside 240 hours. The National Immigration Administration publishes the current list; Kyrgyzstan and Vietnam were added on 20 August 2026.
Can a Shanghai stopover become a mini city break?
Yes, if your entry port is Shanghai and you stay within Shanghai, Jiangsu and Zhejiang. Beijing entry covers Beijing, Tianjin and Hebei instead. Crossing between the two regions on the same permit is not allowed.
Is the policy still current in 2026?
Yes. The policy page was updated on 21 August 2026, and the 65-port network has been in place since 4–5 November 2025. The 240-hour rule itself expanded on 17 December 2024 to cover 24 provinces.
What happens if I enter Shanghai but try to fly to Beijing?
The permit is tied to the entry port’s region, so Shanghai entry does not cover Beijing. Immigration can refuse boarding or entry for travel outside the permitted area.
Do I need to apply for the transit permit before departure?
No. Foreign transit passengers complete an arrival card on arrival in China and are processed at immigration. Carry your onward ticket details, because the confirmed seat and date are what the exemption rests on.
What month is it cheapest to fly to Japan?
Tokyo Tourism’s August 2026 guidance names January–February, late May to early June and September as the cheapest windows, and warns off late March to early April, Golden Week and the October–November foliage season. Our 11 October scan’s cheapest London—Tokyo fare departed 1 December 2026 at €577; its dearest departed 17 April 2027 at €721.
