In Japan, trains for the emperor, the empress, or the empress dowager are called , literally meaning "trains that they use", albeit using an extremely polite word for "use". Trains for the other members of the imperial family are called , meaning "trains to ride" in slightly more common language. However, both "Omeshi Ressha" and "Gojōyō Ressha" refer to a non-scheduled service solely operated for the imperial family. Dedicated imperial carriages were owned by Japanese National Railways (JNR), and these came under the control of the East Japan Railway Company (JR East) following privatization. The dedicated locomotive-hauled set was retired in the 2000s and replaced by the specially-built E655 series EMU, which can also be used as a VIP charter trainset.
