Thanks for the ideas guys
I checked the time tables for the chuo line (Which I take to commute to Kichijoji). The first Chuo to Tokyo leaves at 4:34 from Kichijoji to Shinjuku and arrives before five.
The first train to Nirasaki respectively at 4:37 from Kitchijoji and arrives at 7:20.
I should be able to make it with the train and cab in case there's no one I am able to catch a ride from.
