Train types in Japan

Japan has various train categories, and definitions and translations differ by company, making it complex.

For example, JR refers to cars that can be boarded with only an josha-ken(Passenger/basic ticket) as futsu-ressha(local/normal train).
Tokkyuu(Limited express) trains are defined as trains requiring a (limited) express ticket.

However, definitions vary widely among private railways.
