01 / A NETWORK WITH YOUR NAME ON IT

Small beginnings.
Big connections.

No inherited progress. No shared save. Every account starts with its own world, a starter railway, and ¥75,000 to make a move.

01 / RAIL
▣

Keep Japan moving.

Build connections between Tokyo, Kyoto, Osaka, and beyond. Dispatch trains that accelerate, brake, and respect track separation.

02 / AIR
✈

Make distance disappear.

Open airports, buy air connections, and launch flights to other cities. Watch taxi, takeoff, cruise, holding patterns, and landing.

03 / YOUR WORLD
◫

A map of your own.

Your account receives a unique map seed. Explore generated streets and bordered city districts. Build apartments, temples, markets, clinics, schools, and parks that earn income.

04 / NO LONG WAITS
◷

Keep the momentum.

Airports take 10 seconds, rail connections 12, and air connections 18. Build in parallel while you operate the rest of your network.

02 / YOUR FIRST FIVE MINUTES

How to play.

Plan a little. Dispatch a little. Let the network pay for what comes next.

  1. 01

    Claim your clean slate.

    Create an account. You start with ¥75,000, a unique map, an empty fleet, and a ready Tokyo–Yokohama railway. Progress saves to your account.

  2. 02

    Send the first train.

    Select the starter connection and dispatch for ¥600. Passengers board, travel, and arrive. Each delivered passenger earns ¥120.

  3. 03

    Choose the next city.

    Click a city to build homes, temples, and services, or connect it by rail and air. City buildings take 6–10 seconds and earn income every 30 seconds.

  4. 04

    Take to the skies.

    Build an airport in each city for ¥15,000 each. Once both are ready, purchase the air connection. A flight costs ¥1,800 to dispatch and earns ¥400 per passenger.

  5. 05

    Operate, earn, expand.

    Inspect vehicles, hold or release a service, and follow it on the map. Unlock five connections and deliver 1,000 passengers. Short cooldowns run in real time; simulation speed controls vehicle travel.

Progress is personal and saved on the server. Up to two minutes of offline simulation catch up when you return. Yen is game currency; there are no real-money purchases.
