has anyone here visited koyasan? if yes, do you go on tour? if no, how do you travel to koyasan? i tried googling here but didn't get the answer to my question.

also is it wise to travel to japan during winter? all my japanese friends are against me going there for winter for two reasons: 1) it's too cold that i will be immobile by the weather and 2) i will die from winter. i have survived the wet winter in nz for 4 years so i am fine with the cold. but will there be nothing to visit during winter? i am thinking of osaka and kyoto. otherwise, i will just pack myself to fukui to visit some friends.

thank you!
