Water That Chooses the Time: Mizunomizu Announces Its First Natural Carbonated Water, '15:15 to reset & flow'

Mizunomizu Co., Ltd. (headquartered in Fujinomiya City, Shizuoka Prefecture) has announced the launch of a new product, '15:15 to reset & flow,' under its water brand 'Mizunomizu,' which operates on the concept of 'choosing water by time.'

This product marks the brand’s first natural carbonated water and the first to source water from the Kuju Mountain Range in Kyushu.

For Mizunomizu, which has previously focused on water sources around Mount Fuji and the Izu Islands, this represents a new regional collaboration.

A Proposal: Choosing Water by Time

While people routinely choose coffee, tea, or alcohol based on occasion, they rarely make such distinctions with water.

Mizunomizu has introduced waters tailored to specific times and moments, such as:

・05:15 to set & go

・06:01 for health & recovery

・19:03 for wine & food

・23:59 to relax & sleep

What Mizunomizu proposes is not just water as a beverage, but water that enriches the moment.

'15:15 to reset & flow' was created for those moments in a busy day when one pauses to reset and realign oneself.

The concept is:

'Reset from daily life. A refined, gentle flow.'

The soft effervescence unique to natural carbonation provides a gentle stimulus that shifts your mindset and smoothly transitions you into the next moment.

Mizunomizu’s First Natural Carbonated Water from Kyushu’s Kuju Mountains

The water used in '15:15 to reset & flow' is natural carbonated water nurtured by nature in the Kuju Mountain Range of Kyushu. Naturally formed carbonation, developed over long years deep underground, delivers a gentle fizz and a pleasant aftertaste.

Natural carbonated water is a rare resource, available from only a few locations across Japan.

The company focuses not only on water quality but also on the natural environment and cultural heritage surrounding the source.

The Thought Behind the Design

The label of '15:15 to reset & flow' features a landscape of the Kuju Mountain Range, the water’s source region.

What Mizunomizu aims to deliver extends beyond the water itself.

The scenery of the land where the water originates.

The people who protect that land.

And the natural environment meant to be passed on to future generations.

Mizunomizu believes that conveying the value of the land is also part of a product’s role. That is why the Kuju Mountains are depicted on the label.

The company hopes that when someone holds the bottle, they might wonder:

'Where did this water come from?'

and be inspired to reflect on its deeper story.

Choosing Water is Choosing a Place

'15:15 to reset & flow' marks the first time Mizunomizu has sourced water from Kyushu.

This is not merely an expansion of the product lineup.

It is a new step toward engaging with Japan’s diverse water sources and sharing the nature, culture, and people’s values of each region.

Moving forward, Mizunomizu will continue to promote not only the idea of

'What kind of time do you want to spend?'

but also the new value of

'Which land’s water do you choose?'

Distribution for Hotels, Inns, and Dining Establishments

'15:15 to reset & flow' is not currently planned for general consumer sales.

The product was developed specifically for spaces such as hotels, inns, restaurants, and lounges—places where guests step away from daily life to reset and recharge.

Going forward, Mizunomizu will continue to prioritize the experiential value created by each glass of water, advancing collaborations with facilities and businesses rather than simply selling bottled water.
