Based on Japan, t a t a m i  is an antique dealer’s collective as an independent online marketplace itself for “Contemporary Antiques” with the both ying-yang aspects of ‘Tradition’ and ‘Alternative’ presenting the various types and styles of items individually digged out by each tatami’s unique dealer with diversity and possibility. May the inspiration be with you.


t a t a m i (i.e. tatami antiques) consists of a gathering of the participants (antique dealers in Japan) as a team, which is basically managed by Dai Okumura (hotoke).

The basic business configuration of tatami is that each dealer directly does business with each customer through each listing page in this website and Trocadero. Every single dealer is independent, so that I (Dai) will act as English-Japanese translator between each (non-English speaking) dealer and each customer. I will temporarily receive all inquiries and orders from each customer and then translate them for each dealer before distributing each translation to both sides.

(So, combined shipping is accepted only if the multiple purchased items are listed by the same dealer because of this reason. Please check carefully the further information at the below term of SHIPPING in advance.)
