Metro

You soon get the hang of it! Very efficient, very clean and very air-conditioned.
The stations are massive - but English signs are plentiful and distances to connecting lines given in metres!

I haven't done much today - Could feel the beginnings of a cold when I was stood in the wrong queue up the tower last night, achey and yucky - so had an early night and woke up feeling dreadful! A very lazy day (slept most of it) to hopefully get better in time for my Ryokan experience tomorrow in Kyoto. Maybe an Onsen (hot bath) is called for while I'm there!
