Hey,

We took the Odakyu Line Limited express (Romancecar) from Shinjuku to Gotemba. You can then get a bus from Gotemba station direct to the premium outlets (they are wheelchair accessible and the bus takes about 20 mins from the station).

https://www.odakyu.jp/english/romancecar/timetable/ this is the timetable for the Odakyu line – note that there are only a few direct trains a day otherwise you need to change, which takes a bit longer.

Hope that helps x
