JRPass

Hi there,

Firstly, as you have a 14 day trip planned (and are doing a fair amount of travel), I think you'll stand a good change of a 14 day rail pass being economical. As a 14 day pass is ¥45,100, the best way of understanding if it is worthwhile is to compare it to the equivalent real JR tickets that you'll have to buy. Here's a cost breakdown of your trip based on what you have listed:

1. Kansai airport > Osaka: ¥2400, (53mins, 57km)
2. Osaka > Nara: ¥780, (51mins, 48km)
3. Nara > Osaka: ¥780, (55mins, 48km)
4. Osaka > Kyoto: ¥540, (29mins, 42km)
5. Kyoto > Tokyo: ¥13220, (161mins, 513km)
6. Tokyo > Odawara: ¥3640, (35mins, 83km)
7. Odawara > Tokyo: ¥1450, (36mins, 83km)
8. Tokyo > Nagoya: ¥10580, (126mins, 366km)
9. Nagoya > Kansai airport: ¥8270, (114mins, 247km)

TOTAL: ¥41660 for 9 legs

As you can see individual tickets will work out slightly cheaper than a 14 day rail pass. It's worth bearing in mind that if you want some flexibility to change plans and travel to other areas, or you envisage yourselves travelling in a day trip to other destinations such as Hiroshima or Nikko, you could opt for a 14 day pass for an extra ¥3440 over the standard ticket price and save a lot of money on these journeys.

Hope this helps!
