Moerenuma Park in Sapporo, Hokkaido, Japan.

I visited this place on a cloudy day in 2020 during the pandemic, so it was totally empty. It felt unreal. I took a couple photos, but they don't fully do it justice. Check out the park's website to see what it's all about and for more photos. If you are into liminal spaces, I sincerely recommend this place if you ever get the chance to go visit.
