[Wagamama]

hey all thanks for the fantastic replies...i am gonna be there for 18 days...and the aim of the trip would be to indulge ourselves with the more cultural side(parks,castle etc)....and we dont really
wanna shop,Also if i may ask...if i wanted more scenic nature views wouldnt okinawa be a good choice?or is it too 'couples only go there' kind thing?because i am planning to go with 2 other guys,and we would very much like to have a 'adventure' is this kind of sub urban places...Oh yes we are planning to hit japan in the early December...Does the weather at that time make it impossible to go places Okinawa to hike mountains for example.
if possible i would like to know if there's any major festival happening around that time in japan?

Sorry if i went off topic,and thanks in advance for answering my questions
