In 2001, while living in the United States, I encountered energy drinks through the dance scene and was deeply impressed. After returning to Japan, I found that energy drinks were considered novelty beverages, so I established a comprehensive website in 2013 to share the true appeal of energy drinks. As an energy drink enthusiast, I began drinking them seriously again, collecting over 8,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Flavor of Monster Energy Ultra Vice Guava (Japan)

When I open the can, a sweet, strawberry-like aroma spreads out. The liquid itself is a bright, vivid pink. Now, let me take a sip.

On the palate, clear and refreshing sweetness from guava, peach, and papaya tropical fruit flavors unfolds, followed by a subtle hint of strawberry-like tartness, creating a crisp and lively taste.

The bright, guava-like sweetness is well recreated, perfectly complemented by the light, easy-to-drink texture typical of a zero-sugar beverage. Any unpleasant aftertaste from artificial sweeteners is effectively masked, resulting in a very smooth drinking experience.

The neon grids and retro style, emblematic of 1980s Miami, are also reflected in the energy poem on the back, clearly inspired by Miami Vice.

Compared to the U.S. version, the Japanese edition with a silver top is more understated, while the vivid pink top of the American can makes it more eye-catching and visually striking.

The Miami-inspired illustrations are more detailed on the larger 473ml can than on the 355ml Japanese version, offering a better visual experience.

The iconic Miami colors of turquoise and pink likely draw inspiration from guava’s green skin and pink flesh.
