【What is HAKONE AI?】

HAKONE AI is not an app intended for monitoring or restricting.

This is a completely custom-made artificial intelligence developed in Japan.

Bespoke Family AI

A parent who dictates limits.

Or a parent who builds self-control.

◆Interesting Features Experience the sounds of nature with your fingertips. A moment of finger meditation. The deep resonances produced by geological layers and spring water sometimes create subtle vibrations in your smartphone's speaker. Gently feel those sound waves with your fingertips. That's a signal to pause scrolling. It's a small ritual to quietly return your awareness from your fingertips on the screen to your "real living room." HAKONE AI is not an app that forcibly restricts smartphone use. HAKONE AI is a private AI for families that adjusts its functions to each household's conversations, rhythms, and values, supporting children in gradually learning to reduce their smartphone use on their own.

The families who build technology—epitomized by Silicon Valley—do not resort to taking screens away by force.

【What is HAKONE AI?】

HAKONE AI is not an app intended for monitoring or restricting. This is a completely custom-made artificial intelligence developed in Japan.

Because every family has its own unique rules.

General-purpose AI can only offer generic advice. However, your family is not uniform.

Each child has their own unique daily rhythm. Your household has its own distinct dynamics. Your conversations have their own unique patterns.

That's why HAKONE AI is individually customized to each family.

Like handcrafted haute couture, each one is unique. We employ an analog, manual process. This is a bespoke AI for your family.

HAKONE AI reflects your values, screen time arrangements, daily routines, and how your family communicates.

The goal is not to forcibly remove children from screens. The goal is to support the creation of a home environment where children can gradually learn to pause, step away from screens, and return to real conversations.

I create each piece with care, just like tailoring a one-of-a-kind garment. People call me the AI Tailor.

SUMAHO やめて.jpg

From an era of forced restrictions,
to an era of digital self-mastery.
Beyond bans and limits. It is time to
empower children to step away on their own.

We believe the goal is not to force children away from their screens, but to cultivate their ability to choose when to put them down.
We go beyond simple countdowns; we nurture true digital autonomy.

The future does not require our children to disconnect from the digital world completely. Rather, it asks them to navigate devices and AI with wisdom, and to master themselves.



 

やめれる力.jpeg

Battles over screen time are not a sign of a misbehaving child.

4b.jpg

Perhaps they simply haven't been taught how to back off yet. Just like they don't know how to dismount a bicycle.

自転車の降り方.jpeg

A smartphone is much like a bicycle. Once you learn to ride, you can pedal on endlessly. It is fast, exhilarating, and feels like riding the wind.

The algorithm acts as the guide, teaching only how to accelerate. The next video. The next notification. The next post. It constantly pushes at your back, urging: “Go further. Watch more.”

ARUGORIZUMU.jpeg

Yet, no one teaches them how to step off. How to gently pull the brakes. How to plant their feet back on solid ground.

降り方.jpg

And yet, the world forgets to teach them how to dismount. How to find the brakes. How to stand still on the earth once more.

"That's why we, as parents, must teach them (using HAKONE AI)."

Ultimately, how can you possibly voluntarily close the screen of that tiny device? It's like not knowing how to park a bicycle.


 

OFF.jpeg

Yet, no one teaches them how to step off. How to gently pull the brakes. How to plant their feet back on solid ground. Children simply lack the "skill" to end the ride on their own.

 

JITENNSYA.jpeg

The most important thing isn't to confiscate the devices.

Just as there's a right way to dismount a bicycle, there's a "trick" to stepping away from screens.

Apply the brakes.

Firmly plant your feet on the ground.

Decide for yourself, "That's enough for today."

By gradually developing these skills, children will naturally learn to control their relationship with digital devices.

Deciding for themselves, "That is enough for today."

This is not a forced shutdown triggered by a parent’s timer. Nor is it a device wrestled away by force.
It is the moment your child gently lowers the screen with their own hands, lifts their head, and shares a smile with the family sitting right in front of them.

OYAKO.jpeg

It is the moment they choose, of their own volition, to step off the endless digital wave and land safely back in the physical living room.

In this moment, you are no longer the enforcer shouting, "Put that away." You return to being their greatest ally—standing quietly by their side, smiling back at the child who successfully applied their own brakes.

Not binding them with strict rules or punishments, but cultivating the strength to let go willingly. What HAKONE AI designs for your home is this beautiful, empowering landscape of self-mastery.

Launch the app and rest your fingertip on the smartphone glass for a short Yubizen moment.

Feel the quiet resonance of the Earth through your fingertip.

Yubizen includes field-recorded water sounds from Hakone — spring water resonating through layers of earth, stone, and soil.

This is not a synthesized digital meditation track.

As the sound plays through the smartphone speaker, you may feel a subtle vibration beneath your fingertip.

Deep within the layers of the earth, spring water creates a handpan-like resonance — a natural tone shaped by water, stone, and time.

It becomes a small ritual of return:

the scroll pauses,
the finger rests,
and the living room comes back into view.

HAKONE AI is not a restriction app.

It is a private AI for families, designed to support calmer screen-time routines through rhythm, dialogue, and household design.

A daily routine of scolding and taking away a child's smartphone may, instead of diverting their attention from the screen, rob them of meaningful parent-child interaction in the living room.
OYAKOリビング.jpeg

A daily routine of scolding and confiscating devices may tear your child's eyes from the screen, but it often steals something far more precious: the warmth of conversation from your living room.

Relying on brute force and rigid rules might physically separate the child from the phone, but it inadvertently drives a wedge between your hearts.

What we want to bring to an end is this heartbreaking "Cold War" playing out silently in the living room.

That is why we do not need parents to forcefully take the screen away. Instead, we need a quiet, bespoke design within the home—one that empowers the child to step off the digital wave, on their own, with a smile.

OYAKO117.jpeg

HAKONE AI is not an app designed to restrict screen time.
It is a bespoke private AI exclusively for your family, tailored like haute couture to reflect your parenting values, your unique conversational rhythms, and your child’s individuality.

What we design for your home is not "management" through rigid rules.
We craft a "space for dialogue"—an environment where your child willingly lifts their eyes from the screen, joins you at the table, and shares a laugh about the day’s events.

That moment, in its purest form, is the autonomy born within your child.

A_parent_and_child_are_202605122012.jpeg
Parents and children sharing genuine smiles in the living room.
That is the ultimate goal of HAKONE AI.
A_parent_and_child_are_202605122010.jpeg

This change does not come from punishment or strict time limits.
It begins when children learn how to step away from screens by themselves.

1111.jpg

If moments like this gradually become part of your family’s evenings, how might your living room begin to change?

To see smiles return to the living room, allowing the entire family to end the day in quiet peace. Designing this simple, yet profoundly precious everyday life is my deepest wish as the AI Tailor.

If this singular vision resonates deeply with you, I invite you to open the door that lies ahead.

1. Is HAKONE AI a restriction app? No. HAKONE AI is not a screen-locking or restriction app. It is designed to help families create calmer screen-time routines through dialogue, rhythm, and household design. Instead of simply blocking access, HAKONE AI supports children as they gradually practice stepping away from screens by themselves.

2. Does HAKONE AI monitor my child? No. HAKONE AI is not designed as a surveillance tool. Its purpose is not to secretly watch, track, or police your child. HAKONE AI works through parent-child dialogue, family routines, and information that is intentionally provided with parental involvement. The goal is to help families create a healthier relationship with screens, not to turn parents into guards or children into suspects.

3. Is this a medical or therapeutic service? No. HAKONE AI is not a medical, therapeutic, diagnostic, or emergency service. It does not diagnose, treat, prevent, or predict any medical condition, mental health condition, or school attendance outcome. HAKONE AI is a family-focused digital wellbeing and parent-child communication support service. If you have urgent medical, psychological, or safety concerns, please contact appropriate local professionals or emergency services.

4. How is HAKONE AI tailored to each family? Every family has its own rules, values, routines, and way of speaking. That is why HAKONE AI is not designed as a one-size-fits-all AI. It is tuned to reflect your family’s screen-time agreements, daily rhythm, communication patterns, and household values. A generic AI can give general advice. But your family is not generic. HAKONE AI’s role is to support a calmer, more personal screen-time routine that fits your home.

RESONANCE

7.jpeg

BOND

8.jpeg

DIALOGUE

This symbolizes our commitment to listening carefully to the family's situation.

5. What is Yubizen? Yubizen is HAKONE AI’s small screen-time ritual. During Yubizen, your child rests a fingertip on the smartphone screen while a short natural water sound plays. As the sound comes through the speaker, your child may feel a subtle vibration beneath the fingertip. This becomes a gentle cue to pause the scroll, rest the finger, and return attention from the screen to the room. Yubizen is not a treatment or meditation therapy. It is a quiet routine designed to help families create a small moment of pause.

6. Does my child need to use it every day? No. HAKONE AI does not require strict daily use. However, many family routines become easier when they are repeated gently and consistently. Even a short moment of Yubizen or parent-child dialogue can help create a calmer pattern around screen time. The goal is not perfection. The goal is to build a small routine that your family can realistically continue.

7. Is parental consent required? Yes. HAKONE AI is designed for families and requires parental or legal guardian involvement. Children and minors should use HAKONE AI only with the consent and participation of a parent or legal guardian. HAKONE AI is not intended to replace parental judgment. It is designed to support parents and children as they build screen-time routines together.

8. How does the private assessment work? The private assessment helps us understand whether HAKONE AI is a good fit for your family. You may be asked about your country, your child’s age range, your family’s screen-time concerns, your household rhythm, and what kind of change you hope to create at home. This is not a medical assessment. It is not a diagnosis. It is a first step to understand your family’s needs and decide whether HAKONE AI’s private AI design is appropriate for you.

SANCTUARY

It symbolizes an inviolable safe zone where privacy is completely protected.

10.jpeg

CHOICE

It symbolizes the right to make decisions freely at any time, without being bound by anything.

9. What data is collected? HAKONE AI aims to collect only the information needed to provide and improve the service. This may include parent contact information, country, child age range, family screen-time goals, household routines, selected app inputs, and communication preferences. Data handling, storage, security practices, and the use of any third-party AI infrastructure are explained in our Privacy Policy. HAKONE AI is designed as a family privacy-conscious service, but families should always review the Privacy Policy before using it.

10. Can we cancel the subscription? Yes. Subscription details, cancellation timing, renewal terms, and refund conditions are explained in the Terms of Service and subscription information shown before purchase. HAKONE AI is designed as a private family service, so we encourage families to review the plan details carefully before subscribing.

HAKONE AI is not a medical, therapeutic, diagnostic, or emergency service. It is a family-focused digital wellbeing and parent-child communication support service.
