　OASIZ Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Yu Eto; hereinafter “OASIZ”), which supports brand marketing for major companies centered on SNS × vertical video, will begin an open call for screenwriters starting Wednesday, August 19, 2026, as part of a screenwriter training and recruitment project aimed at business expansion. This open call will be conducted in a format where applicants create and submit one short drama script themed around the OASIZ-operated account “Seikai ga Wakaranai.” Additionally, a webinar for beginners and inexperienced individuals will be held on Monday, September 7, 2026, at 8:00 PM, featuring screenwriter Tomoki Shirakawa, who won the 2026 Mynavi Short Drama Award.

■Project Overview

　OASIZ specializes in vertical video strategy development, planning, and production, and provides SNS marketing support centered on major companies, primarily on TikTok. The cumulative number of views for managed accounts is approximately 5.5 billion, with an average of 750,000 views per video, having supported numerous companies including Nestlé Japan, JAL (Japan Airlines), Rohto Pharmaceutical, Kagome, and Pairs.

The company-operated account “Seikai ga Wakaranai” won the Grand Prize at the “Mynavi Short Drama Award 2026,” and as recognition of planning and production capabilities continues to grow, we are launching a screenwriter training and recruitment project as the core of strengthening our production system to support business growth. Rather than recruiting through traditional job platforms, we will accept script submissions intended for posting on OASIZ’s short drama account “Seikai ga Wakaranai,” select submissions through screening, and produce videos of the submitted works. Through direct guidance by our in-house screenwriter Tomoki Shirakawa, we will discover and nurture the next generation of screenwriters.
