Good to know

Get a SUICA or PASMO car in the metro stations to move around with public transport

Always carry some cash money with you. Not all the shops accepts payments with cards

Get ALWAYS some coins. This are very useful especially when you are running out of cash in your SUICA or PASMO card and you have to pay the difference in the BUS.

Get an E-Sim to use internet everywhere and also highly recommend to download the maps to use without connection in case the E-Sim doesn't work properly and you need translation or check the maps.

Move around with google maps and check properly the right metro exit. If you miss one exit you will find yourself walking hundreds of meters inside the metro station until the next exit.
