I'm going to be in Tokyo-Saitama for about 10 days, plus 5 more days in Yokohama.
I'm going to be commuting to Tokyo from Saitama most of the first 10 days, while in Yokohama I'm going to be more within the area.
I do not have a railpass - and public transportation, as you know, is extremely expensive. I am then wondering what is the best thing to do... have been looking for weekly commuter-passes, but found nothing so far. Is there any other option?
Thank you in advance for any hint!
