- Globally, 67% of respondents in the Ipsos survey supported dedicated bike lanes.
- In Japan, 40% of respondents were unsure about dedicated bike lanes, the highest proportion globally.

- Around 72,000 bicycle-related traffic accidents occurred in Japan last year, with 80% involving motor vehicles.
Japan lags significantly behind other major countries in public support for and the creation of dedicated bike lanes, according to recent analyses. Nikkei's data indicates that the total length of dedicated bike lanes in Tokyo's 23 wards is less than 10% of the network found in Paris.
A 2026 Ipsos 'Mobility Report' survey of 23,722 people across 31 countries revealed that Japan's support for dedicated bike lanes stands at 45%, ranking it the lowest globally. In contrast, the global average support was 67%. Furthermore, 40% of Japanese respondents answered 'Don't Know,' the highest proportion among surveyed nations, suggesting a lack of clear understanding or formation of opinion on the matter.
This low support is speculated to stem from Japan's challenging road conditions, characterized by narrow streets and complex traffic environments where sidewalks and roadways are often mixed. This makes it difficult for residents to visualize the practical impact and safety benefits of dedicated lanes. The report also noted that globally, 55% of people are concerned about road safety in residential areas, with a majority supporting lower speed limits in such zones.
In Japan, the revised Road Traffic Act, effective April 1, 2026, introduced stricter penalties for bicycle violations, including 'blue tickets' for offenses like running red lights or using smartphones while cycling. These measures aim to improve safety, as approximately 72,000 bicycle-related accidents occurred in Japan last year, with about 23% of all traffic incidents involving bicycles. Around 80% of these bicycle accidents involved collisions with motor vehicles.
Copenhagen, Denmark, known for its bicycle-friendly infrastructure, boasts around 400 kilometers of wide, dedicated bike lanes designed to allow uninterrupted cycling, sometimes with traffic light synchronization. This contrasts with Japan's situation, where even existing marked bike lanes can be obstructed by parked cars, forcing cyclists into mixed traffic.
