Nashi Kouen (lit. "Pear Park"; also spelled as nashikouen; commonly abbreviated to nashi) was a website made in early 2024 as a refuge for Heyuri's underageb& users after Rule 0 was born and subsequently enforced (though nashi site admins dispute this by claiming nashi would have existed anyway, and the aforementioned underageb& have since moved on). It hosts a few imageboards and an oekaki instance.
Originally running Kokonotsuba, it has since switched to KotatsuBBS; a new imageboard software written entirely from the ground up by the site's admin riro (AKA pen man) due to his disdain for Kokonotsuba's poor readability.
It died (for the second time) on 2025/2/27 after its administrator decided to not renew the domain.
On March 22, 2025, riro restored the front page of Nashi Kouen but pointed the board links to https://cgi.heyuri.net/goatse/. This took some users by surprise when somebody claimed the site was back in August 2025.
