This article introduces six influencer marketing agencies and platforms in Japan, including CoDigital, CyberBuzz, LIDDELL, Find Model, Toridori Marketing, and Cast Me!. The company overviews and service descriptions below provide a starting point for comparing partners for your next campaign.

Cast Me! by PLAN-B

Cast Me! — Operating Company Overview

Cast Me! is an influencer marketing platform provided by PLAN-B. It combines tools for selecting creators and managing campaign workflows with customer success support. PLAN-B reported cumulative use by more than 3,600 companies in an announcement dated August 24, 2026.

The same announcement introduced a feature that lets brands commission videos or images without requiring the creator to publish a social media post. This provides a way to source creator-produced assets separately from sponsored-post campaigns. Brands should specify the intended channels and usage conditions, because permission to use the delivered content depends on the agreed terms.

Service scope, pricing, and availability should be confirmed directly with each provider. A Japanese-language website does not, by itself, establish whether a company can or cannot support an English-language project. Published client and creator figures are provider-reported and are not directly comparable.
