HAKONE does not take your smartphone away. It gives you one quiet minute before your hand continues automatically.

1. What Happens When You Use HAKONE?

Don’t Ban the Smartphone. Pause the Autopilot.

You open the screen even though there is no notification.

You plan to watch just one video, but then move on to the next.

Before you even notice, your fingers are already moving.

This does not always mean that something is wrong with your brain. It may mean that the brain’s habit-learning system—including the basal ganglia—is efficiently repeating an action you have practiced many times.

HAKONE adds a small pause before the autopilot completes the usual routine.

A Simple Brain Explanation for Young Adults

The basal ganglia work like the brain’s autopilot. They quickly bring back actions you do often.

Control networks that include the prefrontal cortex create a moment to stop and ask:

“Do I really want to do this right now?”

2. A Typical HAKONE Session

Each HAKONE session follows these steps:

You reach for your phone

Pause your finger for 60 seconds

Key Point: The moment you feel the urge to check your smartphone, it is time for "Hakone Time."

The audio features the sounds of natural spring water—recorded from the earth's strata—playing a musical scale.
This utilizes an ancient Japanese technique known as *suikinkutsu* (water harp cave), originally recorded in a Japanese garden.
It produces a mysterious, enchanting tone, much like a pan drum. Because these are the sounds of nature itself—created by the spring water without any human touch—they resonate deeply with the heart.

This is what the screen looks like on the smartphone version. Place your finger inside this circle.

Keep your mind relaxed and at ease as you hold your finger still.
You can do this indoors or outside in a park—it doesn't matter where.

Whenever you feel like using your smartphone—anywhere is fine.
It's that simple.

Draw lines or simple pictures on a piece of paper.
If you have some spare time after finishing your "finger Zen," try doodling instead of looking at your smartphone.
You’ll find it surprisingly effective.
In other words, you’re giving your idle fingers a job to do—drawing.
You probably don't doodle much anymore, right? So, it doesn't matter what you draw; anything goes.

These are drawings made by people actually using "Hakone Artificial Intelligence." They’re all putting their idle fingers to work. Members choose a theme each week and create drawings. You can submit your artwork by mail or as a digital file. Having others see your work is a thrilling and fun experience.

Next, let’s actively put your fingertips to work.
The "Hakone Artificial Intelligence" features 16 different emotion sliders.
Use your fingertips skillfully to adjust the sliders while reflecting on your current mood.
Recalling how you felt throughout the day is a habit unlike any you’ve had before, isn't it?
I created this task as a substitute activity for members who might be itching to scroll.
This works too.

This is the Hakone "16-Emotion Slider."
It leverages a matrix of 152.5 billion possible nuanced expressions, generated by combining 16 distinct emotion sliders with various touch patterns.
These 150 billion combinations are utilized exclusively within a custom-built AI designed specifically for you.

Rather than diagnosing medical conditions, this bespoke environmental design engine visualizes the "mismatch between your current state and your digital environment" and instantly formulates options—personalized alternative actions—for you to choose from.
That is why the system is configured uniquely for you through this custom AI.
The matrix of 152.5 billion nuanced emotions and expressions is never shared with others via the cloud. It functions solely within your custom AI ("Larder 2.0"), serving exclusively as dedicated data to quietly support the choices you make regarding your digital environment.

Reflect on those emotions through brief conversations.

You can also enjoy conversations with "Hakone AI"—a custom-tailored, haute-couture artificial intelligence designed specifically for you.
It acts as a tutor, helping you with things like studying and earning certifications. This way, you can put your spare time to good use in planning your life.

When you have some downtime, you can turn it into study time for your own personal growth.

It’s a system designed to keep you from slipping back into mindless screen time.

You decide for yourself what to do next.

But *what* you actually do—that is up to you.
There is a benefit to practicing how to keep your basal ganglia from running wild.

Watching your favorite videos on your smartphone is fun, too.

Since you’ve cultivated a self that doesn’t get sucked into algorithms, it’s perfectly fine to enjoy your smartphone.

However, in those moments when your hand instinctively reaches for the phone, try doing "Hakone" finger-Zen. That’s the trick.

Your First 72 Hours

 

You Are Not Throwing Away Your Smartphone for Three Days

The first 72 hours are not an exercise in digital asceticism or forced deprivation. You do not need to lock away your device, delete your accounts, or disconnect from the modern world.

Instead, the first 72 hours are a concentrated window of awareness. Each time you notice your hand automatically reaching for the screen, you practice a short, structured sequence:

Notice

Stop

Draw

Identify Emotion

Choose

You do not need to execute this perfectly. Failure is not a setback; it is simply part of the observation.

The primary objective is not to achieve flawless control within three days. The objective is to map your own autopilot. By the end of 72 hours, you will begin to recognize the specific contexts that trigger your automatic sequence:

Does it happen most often during the vulnerable transition of waking up? Does it activate when boredom sets in? Does it emerge as an automatic shield against anxiety or awkwardness? Does it trigger the exact moment a video or scrolling session ends?

Seventy-two hours is not enough time to permanently overwrite a long-standing habit. That is not the goal.

The goal is to introduce a new behavioral option: In addition to "open immediately," you begin practicing "stop first."

A 60-second delay is not a magic cure by itself. Its power lies in being combined with a concrete plan, attention redirection, brief tactile anchoring, and an alternative action. When combined, these elements transform an unexamined impulse into a conscious moment of choice.

The 3-Day Framework

  • DAY 1 — NOTICE

    • Notice the Cue. Begin recognizing the exact moment your hand moves toward the screen before the automatic sequence takes over.

  • DAY 2 — INTERRUPT

    • Stop the Sequence. Practice inserting the 60-second fingertip pause and flowing-water sound to break the immediate momentum of the habit.

  • DAY 3 — CHOOSE

    • Select Your Path. Shift from the pause into drawing (Illustration Reading) and emotional labeling, allowing you to decide your next action with a clear, conscious purpose.

What you are essentially doing is teaching your basal ganglia how to get off a bicycle.

Think back to when you first learned to ride; someone had to teach you how to safely dismount. In much the same way, you must gently teach your basal ganglia—the learning engine guiding your fingertips—how to "dismount" from this automatic habit.

Naturally, this is not something you will perfect in just three days. After all, you will continue to use and enjoy the digital world, won't you?

But you are up against commercial algorithms engineered to target your attention every single second. That is precisely why you need to program a deliberate counter-strategy into your own basal ganglia.

This is why I designed a custom-made AI: to serve as a dedicated navigator, sailing alongside you.

 

Let us fight together to prevent these algorithms from stealing the time of our lives.

A Clear Boundary: We Are Not Medical Professionals As this illustration gently reminds you, we are not medical doctors, psychiatrists, or psychological counselors. HAKONE is a digital self-regulation and behavioral-choice system. It does not diagnose, treat, or cure any medical or mental health conditions.

Our Mission: Digital Defense Against Commercial Algorithms

 

 

While we leave medical treatments to the doctors, our battlefield is the digital realm.

 

We are a team of digital engineers, developers, and system architects. Commercial algorithms are heavily engineered to hijack your attention; therefore, the solution must also be heavily engineered.

 

To fight digital extraction, we must arm ourselves with digital defense. We built HAKONE AI to be your ultimate counter-algorithm—a technological shield designed by engineers to give you your life back.
