1. Cycling street
A cycling street is a street designed or legally designated to give cyclists a prominent position in mixed traffic. Motor vehicles may usually enter, but they must adapt their speed and driving behaviour to the presence of cyclists.
Depending on the country, cyclists may be permitted to use more of the carriageway and motor vehicles may be prohibited from overtaking them. The speed limit, priority rules, permitted vehicles and beginning and end of the street depend on local traffic signs and regulations.
How should I interpret a cycling-priority street in Japan?
Official design guidance includes 車道混在, cycling in mixed carriageway traffic. This arrangement differs from an exclusive bicycle lane or separate bicycle path and does not itself establish Belgium’s cyclist-street rules.

Which driving rules matter on a mixed cycling street in Japan?
On an ordinary carriageway, cyclists generally ride on the left, following the applicable cycling rules. Drivers must pass safely and obey the street’s actual limit; an advisory bicycle marking is not a 30 km/h speed sign.

Lane for cyclists.
English • Traffic sign 327の4の2 • Ordinary bicycle lane. Designates a lane for ordinary bicycles. The law also addresses specified small motorised bicycles and other light vehicles; it does not uniformly exclude every other vehicle category.
日本語 • 327の4の2 • 普通自転車専用通行帯。 普通自転車が通行する車両通行帯を指定しています。法令上、特定小型原動機付自転車や他の軽車両の通行に関する扱いもあるため、すべての他車種を一律に排除するという意味ではありません。

Which priority rules apply on cycling streets in Japan?
Cyclists must obey junction signs and signals. Mixed-carriageway cycling markings guide positioning and continuity; they do not give automatic priority at every crossing road.
