One seat from TPE to Nanjing Fuxing and Songshan hotels
Kuo-Kuang Bus 1843 runs from T1 and T2 at Taiwan Taoyuan Airport into eastern Taipei, hitting Nanjing East Road, Minsheng East Road, and the Songshan area in about 60–80 minutes for roughly US$4–5 (NT$140–160). If your hotel is within a few blocks of Nanjing Fuxing, Minsheng Community, or Songshan, this route saves you the Taipei Main Station transfer that Bus 1819 or the Airport MRT usually require.
Where it runs, when it runs, and how often
The 1843 operates roughly from early morning to late evening, with buses about every 20–30 minutes, and departures posted at the Kuo-Kuang counters in both T1 and T2 landside arrival halls. The route follows the freeway into town, then uses surface arteries in eastern Taipei, which is why it lines up so well with Nanjing East / Songshan / Minsheng hotels but can feel slower than the Airport MRT at weekday rush hour.
Buying tickets and boarding at T1 and T2
Ticket counters for Kuo-Kuang are clearly signed in both terminals on the arrivals level, where you buy a paper ticket for around NT$140–160 before heading to the numbered bus bays outside. Look specifically for the 1843 display; departure boards at TPE sometimes show only Chinese destination names, so having a screenshot of the 1843 route map or your exact stop name before you land helps you match what you see on the screen.
Onboard experience and how to avoid missing your stop
Seats are standard freeway coach style with luggage stored in underfloor bays or a small rack, and many riders on Reddit note that 1843 feels less crowded than 1819 because most tourists default to Taipei Main. Stop announcements in English are hit-or-miss, so regulars pin their hotel or nearest bus stop in Google Maps, watch the blue dot as the bus approaches Nanjing Fuxing or Minsheng East Road, and hit the stop button one intersection early.
Trade-offs, complaints, and when to skip it
Because 1843 runs on surface streets after exiting the freeway, traffic heading into Taipei can push your 60-minute run closer to 80–90 minutes, especially around 8–9 a.m. and 5–7 p.m. Common complaints on r/taiwantravel are overshooting the right stop and then paying for a short taxi ride back, plus late-evening gaps that feel longer than the every-15–20-minute 1819 to Taipei Main.
Practical tip
If your hotel is not within a 5–10 minute walk of a 1843 stop like Nanjing Fuxing or near Minsheng East Road, default to Kuo-Kuang 1819 or the Airport MRT to Taipei Main, then transfer on the MRT; use 1843 mainly when that one-seat alignment lines up almost exactly with your address.
