Interior
The design concept of the interior is "a comfortable moving space with a gentle and secure feeling."[14]
Passenger accommodation consists of longitudinal seating throughout; each seat has a per-occupant width of 46 centimetres (18 in), a 1 cm (0.39 in) increase over those of the 211 series. Wheelchair spaces are provided in every car.[14] Also featured are LCD passenger information displays and security cameras.[14][15] Priority seating areas use a different floor design and color scheme to distinguish them from general-use seating.[14]

History
The fleet was first introduced into service on 5 March 2022, with eight-car sets C2 and C6 being the first to enter service.[16]
Sets from C8 onwards are designated for fleet expansion.[17] This set also has modified cowcatchers at the end cars compared to the previous existing 8-car sets (of which there are seven).
The the first two four-car sets (sets C101 and C102) began appearing in December 2022.[8] As of 21 September 2023, all 23 eight-car sets have been delivered with the appearance of set C23.[18] The thiteenth and fourteenth four-car sets (C113 and C114) were seen test-running as of 8 April 2024.[19]
Four-car sets U1 and U2, which were bound for the Shizuoka area,[9] were delivered in May 2024. These sets feature semi-automatic doors whereby passenger-operated door buttons are positioned next to the train doors.[20]
