Hokkaido's gateway has a railway station beneath the terminal, and is one of the few airports where winter weather genuinely rewrites your plans.
Get the line up as soon as you land, because in winter the first thing many people need to check is whether the trains are running normally. The station is in the basement of the domestic building, so passengers off an international flight walk across first, entirely under cover and clearly signposted. After the belts, do not rush down to the platform before looking at the departures, since heavy snow can change them. If you are travelling with ski gear or oversized bags, allow more time than usual for moving between levels. A few minutes spent reading the situation is worth more here than at any other Japanese airport.

New Chitose is Hokkaido's main airport, a fair way south of Sapporo, with domestic and international sides joined by an internal walk. The domestic side carries a shopping and eating area large enough that people arrive early on purpose. What sets it apart from other Japanese airports is winter: snow can move an entire day's schedule, not just one flight. Anyone flying here between December and March should treat the timetable as provisional.

The free Wi-Fi is available and reaches across the retail floors where people spend the most time, but on a bad-weather day with several delayed departures the entire terminal goes online at once to check status, and speed collapses at exactly the moment you need it. That is why an independent line is worth more here than at a calmer airport: the information you want is the information two thousand other people are refreshing. Do not build a tight connection on the assumption that you will be able to look something up instantly.
A rapid service from the station under the terminal reaches Sapporo Station in about forty minutes and is what most people use in normal conditions. Buses run to hotel districts and directly to the ski towns, which suits anyone hauling equipment. In winter both can be delayed, and roads that have not yet been cleared put the bus much further behind than the train. The route into town alternates open country and forest with built-up stretches, so you keep service throughout but not at big-city strength. Load your map and your accommodation details while you are still inside the terminal.

About forty minutes on the rapid train in normal conditions. The bus takes longer and depends on road conditions, which in winter can differ a great deal.
Snow itself does not cut the signal. What changes is how many people go online at once to check flights, which is why a bad-weather day feels slow even though the network has not gone anywhere.
Not necessarily: buses run from the airport straight to the ski towns, which saves hauling bags up and down several times. Check the operator's current timetable before your travel day.
If you are driving yourself, the map stays open all day and uses more than a city trip. If you move by train and bus it looks like any ordinary city trip, plus more status checking in winter.
