Which of the following is NOT considered a violation of Japanese law regarding parking?

Parking on a public road is not inherently a violation of Japanese law, as there are specific regulations and designated areas where parking is permitted. In many cases, public roads have marked parking spaces that allow vehicles to park legally without violating any rules. This is a significant distinction because the law focuses on the conditions under which parking is allowed rather than making a blanket statement that all parking on public roads is illegal.

In contrast, the other options represent clear restrictions defined by Japanese law. For example, parking within specific distances from motor vehicle entrances, construction sites, and fire stations is regulated to ensure safety and proper access. Violating these specific distances creates hazards that the law seeks to mitigate, which is why those actions are categorized as violations. Thus, the correct understanding of parking regulations in Japan highlights the nuances and permitted actions necessary to comply with local laws.
