What Social Network Public Relations does

Social Network Public Relations (#SNPR), operated by 株式会社ホワイトキャンバス (White Canvas Co., Ltd.), is a Japan-based two-sided SNS marketing marketplace founded in June 2021 and headquartered in Fukuoka. The company operates the 'みんなのSNS掲示板 #SNPR' (Minna no SNS Bulletin Board), a web-based platform that connects small businesses seeking social media promotion with registered influencers who browse campaigns and apply or participate in exchange for gifts or compensation. The platform supports two distinct PR methods — a lottery-based model suited to product PR and a first-come, first-served model suited to physical store visits — and serves primarily local businesses and restaurants across Kyushu (Fukuoka, Saga, Kumamoto, Oita, Miyazaki, Kagoshima, Nagasaki, Yamaguchi), with nationwide claim coverage.

The underlying technology is a bulletin-board-style web application with a multi-criteria search (filtering by category, PR method, age, area, follower count across Instagram, X, YouTube, and TikTok) and an in-platform DM communication function that allows clients and influencers to interact directly. The platform offers no native mobile app, no disclosed APIs or SDKs, and no AI/ML components.

The business model combines a low-cost self-service subscription (¥980/month for unlimited bulletin board use) with higher-touch managed services: a full-delegation tier where SNPR staff handles campaign creation and influencer engagement against a client-set monthly budget, and an influencer scouting service priced at ¥2 per follower (¥5,000 minimum). A separate promotional listing tier is offered at ¥8,000/month or ¥48,000 for six months prepaid. Go-to-market is hybrid: product-led self-service for SMBs, with a community-led influencer acquisition model (free registration, no follower threshold), plus a direct-contact bottom-of-funnel channel. The company is founder-owned and bootstrapped, with no external funding rounds, and is led by Representative Director Yamamoto Soshi.

Core offering

Social Network Public Relations (#SNPR) operates "Minna no SNS Bulletin Board," a Japan-focused SNS marketing platform that connects businesses with registered influencers for social-media PR campaigns. Businesses can either run campaigns themselves on the bulletin board from ¥980/month, or outsource the entire operation to the company's team (full-delegation service). Campaigns are executed via two mechanics: a lottery-based system (for product-distribution campaigns) and a first-come, first-served system (for visits to physical stores), with influencer scouting offered as an add-on.

Product overview

#SNPR is an SNS marketing production service that operates primarily as a two-sided marketplace platform connecting businesses (clients) seeking social media promotion with registered influencers. The core offering consists of the #SNPR main service and its bulletin board platform (みんなのSNS掲示板 #SNPR), which facilitates PR campaign postings. The platform offers two distinct PR methods: lottery-based PR (suitable for product promotions) and first-come first-served PR (suitable for physical stores). Pricing operates on two models—a self-service plan at 980 yen/month for unlimited board access, and a full delegation service where #SNPR staff handles all operations based on client-set monthly budgets. Influencers can join free of charge and participate in PR campaigns for gifts or monetary compensation.
