Japan Rail Pass

A quick dash at lunch time to AWL Travel on Great Portland Street at lunchtime to buy a Japan Rail Pass - this is essential for the Gaijin if you want to save money travelling on the Shinkansen around Japan - basically for £218 it gives you unlimited travel for 7 days on the bullet trains except the Nozomi. Note this is only available for non-residents of Japan.

Essentially i will use this for the majority of my travel outside of Tokyo.
