株式会社off is a Japanese web production and digital marketing consulting company that positions itself as a partner for business growth, drawing on “事業会社のノウハウ” (hands-on operating-company know-how). Rather than offering one-off website builds, it provides end-to-end support across strategy, production, advertising, and post-launch improvement, with a focus on traffic growth, conversion-rate optimization, LTV, and retention.
Publicly available materials show that off covers landing pages, corporate websites, EC sites, banner production, website consulting, SEO/content marketing, social media operations, and performance advertising. Supported ad channels include Google, Yahoo!, Microsoft, Meta, LINE, X, Indeed, and LinkedIn. On the technical side, it mentions Next.js and WordPress, while measurement includes GA4, Search Console, and conversion tags. Its methodology appears strongly KPI-driven, combining traffic analytics, user behavior data, and heatmaps for monthly improvement cycles.
The website production pricing is relatively transparent: plans start from 100,000 JPY. The Light plan starts from 500,000 JPY and includes around 5 pages, template-based design, and launch in as little as 1 month. The Standard plan starts from 1,200,000 JPY and includes original design, brand messaging design, CMS implementation, and 3 months of improvement support. The Premium plan starts from 2,500,000 JPY and covers 20+ pages, brand strategy, guidance for photography/interviews, 6 months of operational improvement, and monthly reports. The final quote depends on page count and requirements; consultation and quotations are free. Long-term post-launch operations require a separate monthly contract.
Its main strength is a complete service chain: brand messaging, conversion paths, SEO, advertising, and ongoing improvement can all be designed within one framework, making it suitable for companies that do not want to manage multiple vendors separately. A small team may also allow faster communication and lower intermediary costs. The limitations are that company information remains incomplete: the team size is listed as only 2 people, the location and establishment date are still marked as in preparation, many service pages are labeled Coming soon, and the crawled text does not show client case studies, ad spend scale, or concrete performance data. As a result, its ability to deliver large-scale projects and the maturity of its methodology should be carefully verified during due diligence.
It is best suited to SMEs, startups, toB/toC companies, and EC businesses targeting the Japanese market, especially teams that need to quickly launch or redesign a website while also working on SEO, LPO, and ad campaigns. Chinese companies expanding into Japan may consider it as a local production and advertising partner. If the primary target market is mainland China, they should first confirm Chinese-language communication, cross-border payment, contracts, ad platform availability, and data-tool compatibility. The site’s accessibility from mainland China cannot be determined from the available text and is marked as unknown; alternatives include comparing Japanese local web production companies, SEO consultants, or China-based digital marketing service providers.
