Yokkaichi City Library, Public library in Yokkaichi, Japan.

Yokkaichi City Library is a public library in Yokkaichi, Japan, offering books, digital resources, and multimedia materials spread across several floors. The spaces are arranged so visitors can easily move between different types of content and reading areas.

The library was founded in October 1908, making it one of the oldest public institutions in the region. It has served local residents continuously for more than a century since its opening.

The library keeps a corner for Yokkaichi-born writers, begun in 1978 as the Niwa Fumio Memorial Room with help from local researchers Koizumi Yuzuru and Matsubara Yoshio. It holds nearly all of Niwa's works plus photographs, newspaper clippings and letters, alongside books by Tamura Taijiro, Kondo Keitaro, Ito Keiichi, Akasegawa Jun and Shono Yoriko.

The library is a 12-minute walk from Kintetsu Yokkaichi Station, or about 2 minutes on foot from the "Shiritsu Toshokan-mae" bus stop served by Mie Kotsu and Sangi buses. It has 103 parking spaces, which fill up on holidays. It opens 9:30–19:00, with special rooms and weekends/holidays closing at 17:00; closed Mondays, the year-end and New Year period, the 2nd and 4th Tuesdays, and during special stocktaking periods.

The library runs a mobile service called jidō bunko: two vehicles, Kamome-gō (third generation, introduced 2005) and Minato-gō (fourth generation, 1998), visit 93 stops around the city. Users may borrow up to 10 items, the same limit as at the main building, and most borrowers are women.
