C4 Hype Zone from Japan is a high-energy drink built for a strong, clean boost. With around 150mg of caffeine, it delivers a noticeable kick without feeling too heavy or overly sweet.
 

The flavor leans smooth with a lightly fruity edge and a crisp finish, making it easy to drink while still packing serious energy. It’s the kind of drink you grab when you actually need it to work.
 

Japanese versions of energy drinks often have slightly different flavor balances, and this one is no exception—cleaner and more refreshing compared to typical U.S. options.
