Beyond Caffeine: How Whole-Leaf Tea Creates "Alpha Wave" Focus

We have all been there: It is 2 PM, you have a deadline, and you reach for a second cup of coffee. Twenty minutes later, you aren't focused—you are anxious, jittery, and your heart is racing. An hour later? You crash.

This is the "Caffeine Rollercoaster."

At Hyaku-pa, we believe energy shouldn't borrow from tomorrow. We designed our No-Brew Ocha to provide a different kind of fuel—a state of "Calm Alertness" that Japanese monks have used for centuries to meditate for hours without falling asleep.

The secret isn't just caffeine. It is L-Theanine.

The Science of "Calm Alertness"

Green tea, specifically the shaded varieties we use (Okumidori and Saemidori), is rich in a rare amino acid called L-Theanine.

According to research from the Tea Science Center at the University of Shizuoka, L-Theanine has a profound effect on the human brain. Unlike coffee, which stimulates the release of cortisol (the stress hormone), L-Theanine promotes the generation of Alpha Brain Waves.

• Beta Waves (Coffee): High stress, "fight or flight," rapid thinking, anxiety.
• Alpha Waves (Hyaku-pa): Relaxation, creativity, "flow state," sustained focus.

When you drink Hyaku-pa, the Caffeine wakes you up, but the L-Theanine smoothes out the jagged edges. It prevents the blood pressure spike and the "jitters," leaving you with a clean, laser-like focus that lasts 4–6 hours.

Why "No Brew" Means More Focus

Most people don't realize that when you steep leaves or a tea bag, you are throwing away the best part. L-Theanine and many antioxidants are locked inside the leaf structure.

Because Hyaku-pa is a whole-leaf powder (a blend of Matcha and Sencha), you ingest 100% of the leaf. You aren't just drinking "tea water"; you are consuming the entire plant.

This means you get:

• 100% of the Caffeine for alertness.
• 100% of the L-Theanine to counteract the crash.
• Insoluble Fiber to slow down digestion, releasing energy steadily over time.

The "3 PM" Solution

Hyaku-pa was designed for the modern workflow. Whether you are coding, writing, or in back-to-back meetings, you need focus that is portable.

Our "No-Brew" tubes dissolve instantly in cold water. No whisk, no hot water, no waiting. Just shake and drink to reset your brainwaves and finish your day strong.
