Getting to Sankeien Garden (Yokohama)

Hi,
My hotel is in minato mirai area, and I plan to take a bus from Sakuragicho station to Sankeien. The guide says to take 54, 58, 99, 101 or 108 from Negishi station.

I have 2 questions -

1. How much is bus fare and do I need to prepare exact change? Do I pay the bus upon boarding?

2. How do I get back to Negishi station? Do I take the same bus from where I got off, or do I need to find a different bus stop?

How much is bus fare and do I need to prepare exact change?

A flat fare of 210 yen one way. There is an exchange machine next to the driver, but it cannot accept 2000, 5000 or 10000 yen bills, as explained on the following page:

It is also possible to pay with a Suica or Pasmo prepaid card (recommended if you stay in the Tokyo/Yokohama area for several days).

Do I pay the bus upon boarding?

Yes.

How do I get back to Negishi station? Do I take the same bus from where I got off, or do I need to find a different bus stop?

It is a bus stop in the same general area as you arrived. If you are unsure, I recommend to ask somebody.

Alfred Seet,

Just so that you know, there also is a tourist information center right in front of JR Sakuragicho Station's bus terminal. Have a nice trip!
