If you are planning to ride Shinkansen between December 23th and January 9th for this year, we recommend you to book your tickets NOW.
Japanese people have custom to return to ancestral family places and celebrate family reunion twice a year; Obon and Shogatsu (the Japanese New Year). These days, many people go on trips as well.
Please refer to the following article for Obon in 2016.
"Obon," the Busiest Season for Shinkansen.

As a result, Shinkansen will be crowded from December 23th to January 10th, and very crowded from December 28th to January 6th for this year. It is likely that you have to line up for Shinkansen and end up standing during the ride if you do not reserve your seats beforehand. Reserve seat tickets will be sold out.
Japan Railways Group sets their own definition and calendar for peak, regular and off-season. If you are interested, you can read it on the page below.

Many people want to book tickets during those peak periods as soon as they fix their travel dates. However, the Japan Railways (JR) group accepts reservation from one month before travel date. You can see some people standing in a line at stations in the morning to buy tickets for peak periods one month later.
