Itayado Hon-dori (板宿本通) runs north from Itayado Station, and together with a number of branch arcades, it connects 18 city blocks with a continuous glass roof (with the proviso that Shin-machi-dori is not fully connected, strictly speaking).
At ~640 feet long, Itayado Hon-dori is one of the shortest arcades in Kobe. Altogether, this group of arcades has a combined length of only ~1900 feet. And yet, as this map shows, these arcades contain over 150 shops (not even including Shin-machi-dori).
It takes ~20 minutes to walk from these arcades to Taisho-suji arcade (map here).
Itayado Kohnin (板宿公認市場), Itayado Nambu (板宿南部), and Shin-machi-dori (新町通) run parallel to Itayado Hon-dori.
Gin-ei Street (銀英通), Itayado Seibu (板宿西部市場), and Itayado Center Street (板宿センター街) run orthogonal to Itayado Hon-dori.
