What to Bring . In some cases, it may be necessary to take a ferry or a plane, and on long journeys, the cost difference between the fastest train and a plane is negligible. Peak Traveling Seasons Peak traveling seasons are around New Year, Golden Week in late April and early May, and the mid-August Obon holidays. For further information please follow the holidays and festivals links. During peak times, transport and accommodation will be booked out, so it is necessary to book well in advance.
Flights are also more expensive, as all discounts are suspended during peak seasons.
Trains Japan has highly efficient and frequent trains servicing all regions. Tickets are expensive, especially for the fastest trains, though various discount tickets are available. Japan Rail Passes Japan rail passes can be bought only outside of Japan. Rail passes are not economical for just one long-distance journey, in which case another discount ticket may be cheaper. Rail passes are good for several long journeys with side trips and for flexibility.
