When did Kotohiki Beach become non-smoking?

I understand that Kotohiki Beach was the first non-smoking beach in the world. When did this come into force? Also I'd be interested to know more of the flora and fauna skirting the beach - thanks, Jonathan

I understand that Kotohiki Beach was the first non-smoking beach in the world. When did this come into force?

I believe it was in 2001, when a by-law was established stating the area as a special protection zone as it says in the link below.

Also in the link, we see a photo on the upper right. The photo is automatically dated as "Sept 22, 2000" and the sign made by local middle school students implies that ashes may damage the precious sand.

Also I'd be interested to know more of the flora and fauna skirting the beach

I hope it helps.

Thank you very much for the information… Jonathan
