Field notes: on the 06:04 out of Shin-Ōsaka

SHIN-ŌSAKA — The 06:04 Nozomi for Tokyo is the first eastbound train of the day and the one most business travellers out of western Japan avoid. It arrives at Tokyo at 08:27, which is thirty-three minutes later than the 05:30 Hikari that a serious commuter would take. The 06:04, for that reason, is unusually empty.

The platform at 05:48 has seventeen people on it. Three are salary-men in black suits reading on phones. Two are women in early-twenties uniforms — hospitality workers on their way out to Tokyo for a shift, judging by the small wheeled cases at their feet. Four appear to be tourists, two with JR rail passes pinned to lanyards. One woman in her sixties carries a shopping bag from Daimaru. The rest are scattered; categorisable only as "travelling."

Before 06:04

The first Nozomi arrives at 05:58 from the Hakata direction, having left Fukuoka at 22:30 the previous evening — a crew-repositioning train that picks up no passengers at Shin-Ōsaka. It leaves again at 05:59, empty, for Tokyo maintenance yards. The 06:04 pulls into platform 26 at 06:01, on the dot, the way Shinkansen do. The doors open. The cleaning crew — six people in pink uniforms — completes a full car turnaround in ninety seconds. Seat-back pillows rotated, rubbish bagged, floor swept, air freshener refreshed. This is the famous seven-minute miracle, compressed, under time pressure, at 06:02 with a December cold blowing across the platform.

The salary-men board first. The uniformed women wait for the rest of the platform to clear, then board the unreserved car at the front. The train pulls out at exactly 06:04:15. You can set a kitchen timer by it.

Inside

Car 5, a reserved car, is thirty-percent full. I am in seat 14D — aisle, east-facing. The seat next to me is empty. Across the aisle, a man in his late thirties, grey suit, opens a bentō from the platform 7-Eleven. It is 06:07. He eats the bentō in six minutes, puts the empty container in the bag-sized cavity under his seat, and sleeps from 06:14 to Shin-Yokohama.

The onboard ticker, in small blue characters, scrolls the weather in English every forty seconds. Nagoya: cloudy, 4°C. Tokyo: partly cloudy, 3°C. At 06:18 we pass through Kyoto Station at 270 km/h. The platform is dark. At 06:42 we are approaching the Nagoya complex. The western sky is orange; the east, over Ise Bay, is already fully lit. This is the specific window I came on this train to watch.

The 06:45 window

For about three minutes — roughly from 06:43 to 06:46 as the train crosses the Kiso River bridges — the sun is precisely perpendicular to the tracks and the carriage interiors are lit sideways, through the east-facing windows, with the kind of pure clear low-angle light that photographers travel half a continent to catch. At that moment, the few passengers who are awake all tilt their faces the same way. The man in the grey suit across the aisle does not tilt. He is still asleep. The ticker reads tsugi wa Nagoya.

Nagoya at 06:52. The platform fills briefly. Twelve people board in Car 5. The train pulls out at 06:53:30. We are now in rush hour for the westbound business commute; the eastbound 06:04 remains half-empty. By Hamamatsu at 07:18 the car is at forty percent. By Shizuoka at 07:34, fifty-five. By Shin-Yokohama at 08:19, ninety. Everyone woke up between Shizuoka and Shin-Yokohama, ate something, and put their phones away. The ten minutes into Tokyo are silent. We arrive on platform 22 at 08:27:00.

Second scene — Himeji, 12:08

Different train, different day. The 12:08 Hikari westbound from Osaka into Himeji, a Tuesday, late April. Platform 31 at Himeji is nearly empty. Two construction workers in white jackets carrying flatbed hard hats. A group of five schoolchildren in uniform with a teacher — field trip to the castle. A tourist couple in technical outdoor gear with a folded paper map that I suspect is out of date.

The temperature is 19°C, breezy, cloud shadow on the castle wall visible from the south end of the platform. Himeji Castle — the white heron, as it is called — dominates the north view from the station's exit. A walkway runs directly up to the castle moat, flanked by a covered shopping arcade whose stalls open at 10:00 and close at 19:00.

The construction workers go west out of the station. The teacher counts her five students twice, then leads them toward the castle. The tourist couple studies the map and looks at the station signs. A local in his seventies — I noticed him earlier on the train — takes a practised left, then a second left, and walks briskly into the shopping arcade toward a soba counter that has a visible line. He knows the line is short at 12:08 because the nearby office workers break at 12:30. This is not my observation; it is his. The wait is the reward of local routine.

Why the 06:04 earns the early alarm

Almost no one boards the 06:04 for practical reasons. The serious business traveller is on the 05:30. The tourist who wants to see Mt. Fuji at sunrise from the train is on the 06:30, because by 07:15 to 07:30 is when the mountain is most dramatically lit against the western light. The 06:04 is a residual train, a scheduling option for people who want to leave Shin-Ōsaka before 06:00 and do not care about the view. What it gives you, as a bonus, is the 06:45 window across the Kiso — that three-minute perpendicular-light moment that no later train catches at the same angle.

I have now taken this train seven times, across three years. The window works the same way every time, within fifteen seconds. The seasons change the intensity: December is sharpest, August most diffuse, April — like this morning — is the compromise position that holds the colour for the longest.

Small administrative notes

Coffee: the onboard cart does not begin service until 07:15. Bring your own from the platform 7-Eleven — they open at 05:00. The platform kiosk's sandwich selection is better at 05:45 than at 06:30, when the commuter rush depletes it. The bento are restocked at 06:00 sharp; if you want one, wait until 06:00:30 and then buy.

Seat selection: the east-facing aisle seat (D side, any car) is the correct choice for the 06:45 window. The three-seat bank on the west side loses the show. A window seat on the east side loses the show partly, because the sun rises past the horizon quickly enough that a close-to-glass angle is saturated by 06:47. The aisle is the right distance.

Next month: a dispatch from a slower train — the ordinary-service JR line from Kyoto to Nara at the cherry-blossom peak. Different scene. Same discipline.
