The intersection of homewear and bathing time, born in the space of PAMM House

PAMM House is the first flagship store of PAMM, a renovated 80-year-old traditional house located in an alley in Omotesando. It is presented as a space that evokes a sense of daily life and warmth.

At this POP UP event, Meimei Hakuhaku, which focuses on the time of bathing within daily life, was unveiled in the space of PAMM House, which proposes time spent at home, primarily through homewear.

By introducing Meimei Hakuhaku in a space that evokes a sense of living, like PAMM House, it provided an opportunity for visitors to feel the product closer to their daily lives.

Welcomed by an original noren curtain for Meimei Hakuhaku, a newly drawn visual by painter Yuta Niwa appeared in the PAMM House space.

About Meimei Hakuhaku

Meimei Hakuhaku is a sake lees bath salt made with sake lees from Tosatsuru Brewery, a sake brewery in Kochi Prefecture with over 250 years of history, and natural domestic salt.

It leads to a romantic bathing time where the mind and body can relax.

The package visual was created by painter Yuta Niwa. Niwa, known for his expressions using the context, techniques, and materials of Japanese painting, expresses the sense of liberation and tranquility that Meimei Hakuhaku possesses.

Additionally, haru. from HUG participated in the creative direction of Tenkai and Meimei Hakuhaku, adding a sensory and narrative perspective to the brand's worldview.

Comments

Comment from Tenkai Brand Manager

I felt that in modern times, we are overwhelmed with information and have somehow come to live only in our minds. We are distancing ourselves from bodily sensations, and the world is gradually shrinking. In such a daily life, I refocused on the time of "bathing." I believe that by regaining the connection between body and mind in the space of the bath, we can awaken people's innate sensitivity. For that purpose, I launched the brand Tenkai.

On the day of the event, I was very happy to receive comments from visitors such as "It smells good" and "My hands are so soft," expressing surprise at the moisturizing power of sake lees, as well as "I can't hold my phone because I'm concentrating on rubbing it." I felt that they were able to sense the quiet time we want to deliver. Furthermore, after the event, it was a day where I strongly felt the affinity with PAMM House again.

Comment from haru.

In the creative process, I focused on how to deliver the sake lees from the historic Tosatsuru Brewery as a modern bathing experience. I viewed bathing as a "voyage" to return to one's own senses, and by incorporating space and humor like in fairy tales or fables, I wanted to create a product that allows people to feel a world slightly different from their daily lives. PAMM is a brand that values time spent at home through pajamas and gifts. Bathing is also a precious moment at home spent for oneself. PAMM House was a place where such feelings overlapped, which is why it felt very natural as a venue to unveil Meimei Hakuhaku. I was very happy to see that feeling conveyed to the visitors through the hand-warming experience.

Comment from a representative of Tosatsuru Brewery Co., Ltd.

We participated in the event from Kochi Prefecture. We are very pleased to see that the sake lees produced in the process of making Tosatsuru Brewery's "Kaori Regular" are reaching many people as the sake lees bath salt Meimei Hakuhaku. Although this was our first initiative to use it as a bath additive, we received the offer positively within the company from the beginning and cooperated. When we actually used it, we felt that the soft aroma of the sake lees itself remained strongly, and the quality of the material was utilized well. Many people who experienced the hand-warming bath purchased the product on the spot, and we are realizing the new potential of sake lees.
