How are the fares calculated?

Fares are calculated using JR East distance brackets. The `calculate_base_fare` tool determines the base price, and `calculate_total_fare` adds any express surcharges and applies the IC card discount if requested.

Does this support Suica or Pasmo cards?

Yes. When using `calculate_total_fare`, you can set the `useIcCard` parameter to true to apply the standard IC card discount.

Can I find the distance between two specific stations?

Yes, you can use the `get_station_distance` tool to retrieve the exact distance in kilometers for a specific JR line.
