Three people. One product.
Sai, Jerry and Jasper. Tokyo and China. Creative direction, ad operations, strategy. No account managers in between.
The studio
We sell the one thing we do ourselves.
Room4 is a Tokyo creative studio with one product: Drop Engine. One customer: founder-run fashion brands doing ¥50M–¥500M a year. One channel: Instagram. We run our own rooms, EP, so the playbook is tested on our own money before it touches yours.
Who does what
Sai
Tokyo
Creative direction and delivery. Directs every shoot.
Jerry
Tokyo
Outbound and ad operations. Runs every campaign.
Jasper
Remote from China
Strategy, offer, closing. Runs the Drop Audit call.
Why us
Trilingual. JP, EN, Mandarin, Cantonese across the team.
We run our own sold-out rooms. We don’t sell what we haven’t done.
Fashion first. If it looks like an agency made it, we redo it.
