China–Japan Flights Cut in Half (2026): How to Still Get to Japan — Seoul & Hong Kong Detour Guide

The short answer

China–Japan passenger flights fell sharply in 2026: the summer-autumn schedule allows just 597 flights per week, down 53% from 1,279.5 a year earlier, and 49 routes have had all flights cancelled. Direct flights are scarce and expensive. But Japan is still reachable: transit via Seoul, a Hong Kong detour, or booking direct flights early all work — and transit is often cheaper than the remaining direct flights. This guide skips the why and covers the how.

Where things stand (data as of October 2026)

Japan's Ministry of Land, Infrastructure, Transport and Tourism 2026 summer schedule: 597 China–Japan passenger flights per week, down 53% year-on-year
As of February 2026, 49 China–Japan routes had all flights cancelled, including Shanghai–Tokyo Narita and Beijing–Osaka Kansai
JAL suspended Tokyo Narita–Shanghai Pudong for the whole season; ANA cut its China quotas sharply
Remaining flights run at 40–48% load factors (breakeven is around 70%)
Free refund/reschedule extended to 24 Oct 2026: Air China, China Eastern, China Southern and others allow a full refund or one free change (±3 days, fare difference only) for Japan tickets bought before 26 Jan 2026 12:00 with departure between 29 Mar and 24 Oct 2026
Winter season (from 25 Oct 2026): no large-scale capacity additions announced as of writing — expect capacity to stay low

Route 1: transit via Seoul (best overall; north/east China)

Why it works: China–South Korea flights grew 9.8% year-on-year in the first four months of 2026 — capacity is plentiful. Seoul has dense flights to Tokyo, Osaka, Fukuoka and Sapporo, and a two-leg through-ticket often costs less than today's direct flights.

How to do it:

Buy a through-ticket (single ticket number): baggage is checked through to Japan, no re-checking during transit
Connection time: 1.5 h+ within the same Incheon terminal; 2.5 h+ across terminals (shuttle train required)
Staying airside (transit under 24 h) requires no visa at all — just follow the Transfer signs

Visa note: if you want to leave the airport for 1–2 days in Seoul, Korea's transit visa-free policy has seen changing interpretations recently. The official 30-day transit visa-free list covers US, Canada, Australia, New Zealand and 32 European countries' visas; whether a Japan visa qualifies is disputed across sources. Confirm with your airline or the Korean embassy/consulate before departure.

Route 2: Hong Kong detour (best for south China)

Hong Kong–Japan flights are unaffected: fully normal since late March 2026. Cathay Pacific and HK Express operate 20+ daily Hong Kong–Tokyo flights, plus Osaka, Fukuoka, Nagoya, Okinawa and Hiroshima
Low fares: HK Express Hong Kong–Osaka from HKD 670, Fukuoka from HKD 610, Okinawa from HKD 270 (2026 fares, excluding tax)
Mainland residents can transit Hong Kong visa-free for 7 days with a valid passport + onward ticket (no Hong Kong/Macau travel permit needed)
Best from Shenzhen/Guangzhou; from the north, the Seoul transit is shorter

Route 3: direct flights — book early, use the free refund window

Cities with remaining direct flights (April 2026 data): Beijing, Shanghai, Harbin, Tianjin, Guangzhou, Fuzhou, Qingdao, Xiamen, Jinan, Hangzhou, Haikou, Chongqing, Nanjing; Wuhan has none
Not on the list? Look at the nearest direct-flight city plus a high-speed rail connection
Book 2–3 months ahead; midweek departures (Tue/Wed) usually cost less than weekends
Flight cancelled? Check free refund/reschedule eligibility first — don't rush to buy an expensive replacement
Note: tickets departing after 24 Oct 2026 fall outside the free refund policy — normal airline rules apply

Money-saving tips

Transit vs direct: direct prices are inflated by scarcity; transit often saves 30% or more
Always compare through-tickets, not two separate tickets (separate bookings mean no baggage check-through and your own connection risk)
LCC sales: Spring Airlines, Juneyao and others regularly discount China–Japan and China–Korea tickets
Free refund/reschedule rights usually require booking on the airline's own site — check the rules before booking via an OTA
Travel off-peak and midweek; avoid sakura and autumn-foliage peaks

Arriving in Japan: entry formalities

Whichever route you take, fill in VJW (Visit Japan Web) before departure: immigration and customs declaration are now merged into a single QR code. Fill it in ahead, screenshot it, scan and go — no standing in line at the airport.

FAQ

Do I need a visa for transit? No — staying airside under 24 h requires none. Entering the country for sightseeing requires confirming the transit visa-free policy first (see Route 1).

Do I need a Hong Kong/Macau travel permit for the Hong Kong detour? No. A passport + onward ticket gives 7 days visa-free transit.

Are tickets expensive now? Direct flights are pricey (scarce supply); transit and early booking stay reasonable — Shanghai–Osaka direct was as low as ¥797 in April 2026.

Will capacity recover in the new season? No large-scale additions have been announced for the winter season starting 25 Oct — plan around low capacity.

Bottom line

North China → transit via Seoul. South China → detour via Hong Kong. Direct available → book early. Cancelled → use the free refund window first. All three routes are running normally; plan 2–3 months ahead and Japan is still on.
