No, entry to the arcade itself is free. However, individual shops, restaurants, cafes, and museums within the complex charge separately for their products, meals, and services. You can walk through and browse without any entrance cost.
Take the JR Hakodate Main Line from Sapporo Station to Otaru Station, which takes approximately 30-40 minutes. From Otaru Station, the arcade is about a 10-minute walk. You can also walk there from the famous Otaru Canal area, as it's located in the central tourist district.
You can shop for local crafts, Otaru glassware, music boxes, and traditional Japanese goods while experiencing a nostalgic 1920s atmosphere. The arcade also features restaurants serving Hokkaido cuisine, cafes, and small museums with historical photographs and artifacts from Otaru's commercial past. It's primarily a cultural shopping and dining experience.
Since Otaru Denuki Koji is a covered indoor arcade, it's an excellent destination year-round, especially during Hokkaido's cold winters or rainy days. Many visitors combine it with other nearby attractions like the Otaru Canal and glass-blowing workshops, making it convenient to include in a day trip from Sapporo regardless of the season.
