Hi. My friends and I will be in Japan this October for seven days. However i will arrive via Kansai airport ahead of my friends - I will arrive Sunday evening and my friends will arrive the following morning. I will stay overnight in Namba, then follow them to Tokyo. Anyway, we have not finalized yet our itinerary, but these are more or less the places that we will visit:
Sunday - Kansai to Namba
Monday - Namba to Tokyo
Tuesday - Tokyo
Wednesday - Tokyo to Osaka
Thursday - Osaka to Kyoto and Nara
Friday - Osaka
Saturday - Osaka to Kansai Airport
Based on the above, is a JR pass necessary? When will I start using it? From Namba, where will I take the bullet train to Tokyo? Do I need to change trains to get to Tokyo?
Sorry, the railway system is kind of confusing to me.
Thanks.
