Aokigahara National Forest.

Aokigahara National Forest, situated at the base of Mount Fuji, is a captivating wilderness often called the “Sea of Trees.” Its dense forest, formed from ancient lava flows, features a unique ecosystem with exposed, intertwined roots and a variety of flora and fauna, including deer and various bird species. The forest is punctuated by intriguing caves like the Fuji Fuketsu Wind Cave and the Narusawa Ice Cave, each offering a glimpse into its geological history. Each season paints the landscape differently—vibrant greens in spring, deep summer canopies, striking autumn colors, and a serene snowy blanket in winter. While Aokigahara is renowned for its natural beauty, it also carries a somber history associated with mental health struggles, drawing visitors who seek both solace and reflection amidst its haunting charm. Guided tours enhance safety while educating visitors about this multifaceted environment.
