Entrust a thought to someone who matters
TSUTO is a private experience for entrusting, giving and continuing a thought between two people. Through NFC-enabled objects in many forms, it opens a place shared with someone who matters.

Some things matter too much for an ordinary message. Some deserve to remain close, even as time passes. TSUTO places that thought in a small form and carries it to one person only.
Entrust it. Give it. Open it. And let the connection continue.

THE SECOND BUTTON
In Japan, a second uniform button is sometimes given to someone special on graduation day. Its meaning lies not in the object itself, but in the feeling entrusted to it. TSUTO carries that quiet spirit into a form made for today.
THE GIFT
Leave the first words, photograph or video you want someone to keep.
Place the small TSUTO into the hands of the person you had in mind.
When the receiver brings a phone close, the protected thought is opened.
From that moment, it becomes a private message board shared by two people.
Product design

THE PENDANT
One face recalls a button. The other carries the TSUTO mark, formed by the joining of つ and と. Quiet and unadorned, it is designed to remain close in everyday life.
SIMPLE NFC
There is no dedicated app and no battery. Bring an NFC-compatible smartphone close to the pendant and open the link that appears.

Move the smartphone towards the pendant.
Choose the prompt displayed on screen.
Use your access key to enter the place between you.

PRIVATE SPACE
Giver and receiver each have their own way in. If you keep more than one connection, My TSUTO brings them together in one private place.
QUIETLY PROTECTED
Giver and receiver each have a different access key. The first thought remains protected until the receiver arrives, and attachments are encrypted on the server.
