On March 31, 2026, the latest addition to the Monster Energy lineup, “Monster Ultra Vice Guava,” was released across Japan. This product is the newest entry in the “Ultra” series, designed for those who want to enjoy great flavor without worrying about sugar or calories. The series has garnered immense support from health-conscious fans in Japan, and this time, a tropical-inspired flavor has officially landed on Japanese shores.

Miami’s Hype in a Can! The Appeal of “Monster Ultra Vice Guava”
Monster Energy holds an overwhelming share of the energy drink market in Japan. Among its offerings, the “0 Calorie, 0 Sugar” Ultra series is particularly popular as a guilt-free refreshing beverage. The new “Vice Guava” is, as the name suggests, a drink that fully showcases a crisp guava flavor (non-juice).
This new release was developed with the image of the vibrant and glamorous streets of Miami. It encapsulates the expansive atmosphere of Miami in a single can—from its Latin energy and top-tier motorsports to the hot clubs lining the beaches. Despite being zero calories, Monster’s signature powerful energy blend remains fully intact. It’s the perfect partner for when you need to shift your mood during a busy workday or when you want to enjoy your downtime to the fullest.
