Nagi no Asu kara, Houkago Teibou Nisshi Recommendations
If you are just craving the ocean, these two are great picks. The narratives are quite different, but the nautical settings are fantastic in both. One is a romance/supernatural drama and the other is simply about a fishing club, but both focus heavily on human coexistence with nature, specifically the sea. I'm massively biased towards anything ocean-related, so these two both did wonders for me. Perhaps they will do the same for you.
Despite the differences in genres, the story of Houkago Teibou Nisshi and Nagi no Asu kara both set place in a seaside town, giving a similar sea and ocean vibe. Recommended if you need something different yet similar vibe.
