Step 2: Train Pass and Bike Cover
I had a JR rail pass which is only for tourists. It must be bought outside of the country. It's still expensive, but a lot cheaper than individual train tickets. When bringing your bike onto a train, you have to put a cover over your bike. I used this big brown bag. Later I bought a much lighter bike cover in a dollar store. In the station I partly folded the bike as seen here for ease in wheeling it around.
