| Tokyo → Amsterdam (AMS) → Dublin | KLM, JAL | 15h – 17h | AMS-DUB 1h 30m; Schiphol efficient |

Key Variables
- Tokyo airport: HND (Haneda) better for connections; NRT (Narita) more long-haul slots
- Dublin airport: DUB only — no alternative
- Layover: 90–180 min ideal; <90 min risky at LHR/CDG/FRA
- Season: Summer = more frequencies; Winter = weather delays (LHR, DUB fog)
- Visa: Irish visa required for many passports; UK visa NOT valid for Ireland (Common Travel Area ≠ visa union)
Time Zone Math
- Japan (JST): UTC+9 (no DST)
- Ireland (GMT/IST): UTC+0 / UTC+1 (DST: last Sun Mar – last Sun Oct)
- Difference: 8 hours (winter) / 9 hours (summer)
- Depart Tokyo morning → arrive Dublin morning (same day, local time)
Pro Tips
- Book single ticket (interline baggage, rebooking protection)
- Prefer HND-LHR-DUB or HND-HEL-DUB for speed/reliability
- Consider overnight at London if >4 hr layover — reduces fatigue, sees city
- Aer Lingus / BA / JAL / ANA / Finnair = most reliable JV partners
No magic shortcut. 14+ hours is the floor. Pack for the long haul.
