Taxi Stands in Like a Dragon: Infinite Wealth are one of the ways to fast travel around the map. You can take a cab and choose a destination from a list of unlocked taxi stands. You can also open the map, hover the cursor over one of the taxi stand markers and accept your choice to quickly travel to that location.
The cab trip is not free, you will have to pay a small fee. Choosing a place using the map is a bit more expensive than taking a taxi cab, but much more convenient because you can travel from anywhere.
You will unlock most of the taxi stands when you explore the nearby area. A few will be revealed as the game's main story progresses. Some marked locations are just end destinations.
A taxi cab is also a way to travel between Isezaki Ijincho and Kamurocho but only later in the game (Chapter 8+).
