The Subway: Three Lines, and That's the Whole City
Sapporo's subway is refreshingly simple after Tokyo. Three lines, colour-coded, all crossing at Odori Station in the centre. The Namboku line (green) runs north-south through Sapporo Station, Odori and Susukino — it is the line you will use most. The Tozai line (orange) runs east-west through Odori and out to Maruyama Park and Shin-Sapporo. The Toho line (blue) runs from Sakaemachi in the north, past Sapporo Station and Odori, south to Fukuzumi.
Fares are distance-based, from 210 yen for the shortest hops up to 380 yen for the longest, with children at 110 to 190 yen. In practice almost every tourist journey inside the central area costs 210 or 250 yen. Trains run roughly 06:00 to just after midnight and are frequent enough that you never check a timetable.
One quirk worth knowing: Sapporo's subway trains run on rubber tyres on a concrete guideway rather than steel wheels on rails, which is why they are unusually quiet and why they cope with the winter climate so well. Practically, it means the subway is the one transport mode in Sapporo that snow never disrupts.
