Soroban Calender

Soroban Calenderは、たまを弾くというシンプルな手の感覚を通じて、日々の時間の移り変わりを味わうプロダクトです。
古くから数を数える道具として使われてきた「そろばん」の仕組みを踏襲し、数字を使わずに日付を表現するミニマルな構造に仕上げました。365日、毎日少しずつ形を変え、一度として同じ表情にはなりません。木のたまは使い続けることでゆっくりと色味を深め、時間とともに味わいを増していきます。

Soroban Calendar is an object that allows you the passage of time each day through tactical sensation and routine, by sliding each bead everyday.
Drawing from the mechanism of an abacus, a tool used for counting since ancient times, it features a structure that expresses date without using numbers or letters.
Each day of the year, the shape changes slightly, and the calendar will never look exactly the same. Over time the wooden beads slowly deepen in colour with continued use, gaining patina and 'growing' with you over time.
