what is the best train way to go from Shinjuku to Yokohama Chinatown That may depend on which station in Shinjuku you start from, but I suppose a route via Ebisu sounds simple.
If you start from a subway station on Tokyo Metro Marunouchi or Fukutoshin Line and if you can avoid morning and evening rush, also a route via Shinjuku-sanchome can be a good choice.
(Note: On weekdays in Shinjuku-sanchome Station, you cannot use the direct pathway to get from Marunouchi Line to Fukutoshin Line during 7:50 - 9:20.)
In the transfer in Shibuya, you need to get from the JR track on the 2nd floor (above the ground) to the Tokyu Tokyo Line track on the 5th basement, which was relocated in March 2013.
In the transfer in Yokohama, you need to get from the JR track on the 1st floor (= ground floor) to the Tokyu & Minatomirai track on the 5th basement.
Each of the four routes requires about 50 to 60 minutes if you start from Shinjuku Station of JR or of Tokyo Metro. The one-way fares in total from Shinjuku will be about 600 to 800 yen per adult. You can use a Suica Card (or another compatible IC card) on the whole route.
