Oyama Sushi Mill Valley is a relaxed neighborhood spot that primarily focuses on Japanese sushi, but also reflects the broader influence of East Asian dining culture that many guests in the area enjoy—including Korean-inspired flavors found in some modern sushi kitchens today.

The menu highlights fresh sashimi, classic nigiri, and a variety of specialty rolls made with attention to balance and presentation. In a casual, welcoming setting, it’s a go-to place in Mill Valley for a light, fresh meal that blends traditional Japanese technique with the kind of contemporary Asian fusion influences—sometimes including subtle Korean-style spice or seasoning—that many diners appreciate.
