Sapporo Ramen Republic, Food theme park in Chuo-ku district, Sapporo, Japan.

Sapporo Ramen Republic is a collection of separate ramen restaurants stacked on the 10th floor of the ESTA building directly across from JR Sapporo Station. Each shop displays its own regional style, from traditional broth recipes to contemporary takes on the dish.

Sapporo Ramen Republic opened on 1 October 2004 on the 10th floor of the Sapporo ESTA building in front of JR Sapporo Station. It was produced by Namco's planning team Team Nanda and supervised by food journalist Hantsu Endo, with Sapporo Station General Development operating it. In October 2009 the Kanagawa shop Nantsu-tei became the first ramen restaurant from outside Hokkaido to open a branch here. The facility closed on 31 August 2023 when Sapporo ESTA shut down for redevelopment tied to the Hokkaido Shinkansen extension.

The name frames the floor as a "republic," and in 2014, for its tenth anniversary, entertainer Taisuke Sugimura was installed as its "king." The shops are branches of ramen restaurants from across Hokkaido, and from 2009 the Kanagawa chain Nantsu-tei became the first from outside Hokkaido to open here. Menus rotate every six months to two years.

The facility occupied the 10th floor of the Sapporo ESTA building in front of JR Sapporo Station and closed permanently on 31 August 2023, when ESTA shut for the station-area redevelopment tied to the Hokkaido Shinkansen extension. It cannot be visited; some of the ramen shops trading at closure moved to nearby locations.

The interior recreates streets from the Showa period with traditional shop fronts and vintage signs that feel like stepping back in time. This design choice wraps the eating experience in a nostalgic setting that connects food to memory and history.
