we are arriving in Osaka on the 31 March and departing on the 16 April - 17 days
we plan to travel from Osaka to Hiroshima to Fukuoka to Kyoto to Tokyo to Sendai - as much as possible
if I choose the Green card the 14 days is £453 and the 21 is £589 - difference is £136 per person
I am either 3 short or pay for 4 days extra
is it worth it? paying the extra for 21 days?
any assistance would be great
thank you
