Most Shinkansen “bullet trains”have Ordinary (second class) cars, and Green (first class) Cars.Green car seats have both reserved and non-reserved car seats. Usually Green car is quiet and less crowed, and the train feels more spacious and comfortable. Shinkasen seats on the Green car have 4 rows (2 rows + 2 rows) and Ordinary car have 5 rows of seats ( 2 rows + 3 rows) that width of the green seat is wider. The green car has a deeper reclining angle and you can recline the seat deeper than the Ordinary car.※Some Sanyo and Kyushu Shinkansen have 4 rows of seats in a standard car, which is the same width as a green car.※During busy times, the train is almost full, and some people have choice to take the green car because the ordinary car is full, so tranquility is not guaranteed.
