When does the last Nagoya subway train actually leave?
Look at a Nagoya Municipal Subway timetable and the final departure reads 00:15 or 00:30. That is 12:15 AM or 12:30 AM, just past midnight. Not noon. The last trains on most lines leave between 00:00 and 00:30. Misread 00:15 as a lunchtime departure and you will be stranded. Taxis run 24/7, but a late-night surcharge of roughly 20% applies from 22:00 to 05:00.
Train timetables for JR Central, the Tōkaidō Shinkansen, and private lines like Meitetsu all use 24-hour format. A departure listed as 23:45 is 11:45 PM. A Shinkansen at 06:20 is 6:20 AM. The system is universal across Japanese rail: printed schedules, platform displays, and apps all speak 24-hour time. Hospitals, TV listings, and some digital clocks on ATMs or convenience store registers do the same. Anywhere ambiguity carries a cost, the 24-hour clock rules.
Where 12-hour time is used
In casual conversation, on shop signs, restaurant menus, and most retail hours, Nagoya uses the 12-hour clock. You will see "営業時間 10:00-20:00" (business hours 10:00 AM to 8:00 PM). Department stores like Mitsukoshi and Matsuzakaya typically open 10:00 to 20:00. Shopping malls such as Oasis 21 and Nagoya PARCO run 10:00 to 21:00. A restaurant's last order at 21:00 is 9:00 PM.
When speaking, people say the hour and add 午前 (gozen, "before noon") or 午後 (gogo, "after noon"). 午後3時 (gogo san-ji) is 3:00 PM. 午前0時 (gozen reiji) is midnight. 午後0時 (gogo reiji) is noon.
How to read a Nagoya train schedule in 24-hour time
Reading a Japanese timetable is straightforward once you know the rule:
- 00:00 to 23:59 follows standard 24-hour notation.
- A time like 24:00 appears on some late-night bus schedules to mean midnight at the end of the current day. Most train and subway timetables simply use 00:00 for that moment.
- The trap: 00:15 is 12:15 AM, just after the date changes. Not 12:15 PM. Visitors routinely misread this as midday.
| 24-hour time | 12-hour time | Japanese term | Meaning |
|---|---|---|---|
| 00:00 | 12:00 AM | 午前0時 (gozen reiji) | The day's first minute |
| 04:37 | 4:37 AM | 午前4時37分 | June solstice sunrise in Nagoya |
| 06:56 | 6:56 AM | 午前6時56分 | December solstice sunrise in Nagoya |
| 12:00 | 12:00 PM | 午後0時 (gogo reiji) | Noon |
| 16:43 | 4:43 PM | 午後4時43分 | December solstice sunset in Nagoya |
| 18:03 | 6:03 PM | 午後6時3分 | March equinox sunset in Nagoya |
| 23:45 | 11:45 PM | 午後11時45分 | Late night |
Why Nagoya train timetables show 00:00 for the last departure
A timetable showing 00:15 means the train departs fifteen minutes past midnight, early in the morning of that date. Read it as 12:15 PM and you will miss the train by half a day. The 24-hour system removes that ambiguity. A service running just after the date change belongs to the same operating day as the previous evening's runs. The notation makes it obvious that 23:45 and 00:15 sit only 30 minutes apart, even though they straddle two calendar dates.
Japan does not mandate a single official time notation. The 24-hour clock governs anything demanding precision: transport, broadcasting, medical records, official documents. The 12-hour clock governs everyday life: shop hours, casual speech, signage. The dual system works because context usually signals which one applies. A sign reading "open 10:00-20:00" means 10:00 AM to 8:00 PM. A timetable reading "depart 07:23" means 7:23 AM. Trouble only brews when someone spots a 24-hour time outside its usual habitat, or assumes 00:00 means noon.
How Nagoya's sunrise and sunset times fit the 24-hour clock
On the June solstice, 21 June 2026, sunrise in Nagoya comes at 04:37. That is 4:37 AM. On the December solstice, 21 December 2026, sunset arrives at 16:43. The 24-hour clock keeps these times unambiguous regardless of season. Nagoya's daylight swings from 14 hours 32 minutes on the June solstice to 9 hours 47 minutes on the December solstice. The March equinox delivers sunrise at 05:57 and sunset at 18:03. The September equinox gives sunrise at 05:39 and sunset at 17:50.
Photographers lining up shots of Nagoya Castle or Atsuta Jingū rely on these figures. Event planners and farmers in surrounding Aichi Prefecture do too. The 24-hour clock means nobody has to guess whether 06:56, the December solstice sunrise, belongs to morning or evening.
