Ready for a job among the stars? ÉTOILE LINE is now hiring new guide assistants.
About
From star to star. Tonight, carrying a special journey.
ÉTOILE LINE
A luxury interstellar sleeper tour train running through the cosmos—ÉTOILE LINE.
Planets in bloom, worlds of blue seas, auroras that dye the night sky. Sometimes running alongside pods of star whales, sometimes visiting gardens where meteors fall.
This train carries more than just the time it takes to reach a destination. The stars flowing past the window, the quiet moments deep at night, the casual words exchanged with someone. It is a sleeper train for star-touring, where everything becomes a single "journey."
Train Facilities
Another home among the stars.
The train is equipped with facilities to help you enjoy your journey at a leisurely pace.
A Dining Car where you can savor meals while gazing at the starlight. An Observation Lounge where the universe spreads out through large windows. A Bar Counter where you can enjoy a late-night drink. An Observation Car for quietly taking in the scenery.
The crew members also work, eat, rest, and sleep within this long train.
There is no need to rush until you reach your destination. Even the time spent heading to the next star is a vital part of the sightseeing on the ÉTOILE LINE.
Private Sleeper Cabins
Good night. Until we reach the next star.
Guests spend their nights in Private Sleeper Cabins prepared for each individual.
A soft bed, a large window, storage for luggage, and a washbasin for freshening up. Once the door is closed, it becomes a small private room in the middle of space.
If you sleep with the curtains open, you might see the starry sky until the very last moment you close your eyes.
And when morning comes—beyond the window, a different star than yesterday awaits.
Tourist Destinations
What kind of star will we land on today?
Flower Planet Floria, where flowers glow faintly when night falls. Ocean Planet Nereia, for touring undersea cities and coral reefs. Aurora Planet Aurora, where the sky is colored by auroras all year round.
Furthermore, the Star Whale Route Lyvia, where you can watch pods of giant star whales, Star Festival City Festa, where festival lights fill the night, and Meteor Garden Asterion, where you can lie down and watch the rain of shooting stars—.
The ÉTOILE LINE visits countless stars, each rich in individuality.
You can accompany a guided tour at the stopover, or go sightseeing with colleagues if it's your day off. Shop at the markets, eat local specialties, or take photos.
There is no single correct way to spend your journey.
Newcomer's Guide
And this time, you are not a "guest."
Welcome to the ÉTOILE LINE.
You are the newly assigned Tour Guide Assistant. You will learn the job bit by bit while supporting the senior guide, through tasks such as preparing tourism materials, guiding passengers, roll calls, and accompanying tours.
The reticent conductor in charge of the train. The reliable tour guide. The gentle attendant making his rounds. The bartender coloring the night lounge. The chef turning the flavors of each star into cuisine.
You will work with them, sometimes rest with them, and occasionally go out to play on the planets where you stop.
Days spent working. Nights spent doing nothing. Holidays spent landing on unknown stars.
This is a story of the slow journey of crew members living while traveling among the stars.
