1. Trains and Subways : The Main Modes of Transportation in Japan
    1.1 Japan Rail Pass (JR Pass)
   If you plan to travel between cities, the Japan Rail Pass (JR Pass) can be a cost-effective option.
   This pass allows unlimited travel on the Shinkansen (bullet train) and other JR trains for a specified
   period (7, 14, or 21 days).

   1.2 Subways in Major Cities
   1. Cities like Tokyo, Osaka, and Kyoto have extensive and efficient subway networks.
   2. Use Google Maps or apps like Japan Transit Planner to find the best routes.
   3. Subways are usually faster than buses and help you avoid traffic congestion.

   1.3 IC Cards (Suica, Pasmo, ICOCA)
   1. For city travel, use IC cards such as Suica, Pasmo, or ICOCA.
   2. They can be used to pay for subways, buses, and even some shops or vending machines.
   3. They are more convenient than buying single tickets every time you use public transportation.

2. Using Buses in Japan
   1. Buses are more commonly used in Kyoto to reach tourist spots that are not accessible by subway.
   2. Pay with an IC card or cash (payment is made at the front or back depending on the region).

3. Taxis in Japan: When Should You Use Them?
   1. Taxis in Japan are known to be expensive, but they can be a good option when traveling in a group
   or when public transportation is unavailable.
   2. Use apps like JapanTaxi or Uber for easy booking.
   3. Taxi doors open automatically, so there’s no need to open them yourself.

4. Bicycle Rentals
   1. Some cities, such as Kyoto and Takayama, offer bicycle rental services for tourists.
   2. It’s a great option for leisurely exploring sightseeing areas that aren't too large.

5. Car Rentals
