RETZ is a web business support service operated by Yogiretsu in Japan. Its core positioning is “小さなお店のかかりつけWeb担当” — essentially an on-call web manager for small shops. In practice, it provides remote outsourced web support for small stores and small business operators. It is not a standard SaaS product; it is closer to a monthly subscription-based digital operations assistant / website and online business maintenance service.
The service covers a fairly broad, practical set of day-to-day business tasks: website content updates, access analytics reports, online ad creation and registration, ad performance measurement, data aggregation and analysis, initial setup of LINE Official Accounts, support for web meetings and seminars, document creation, income and expense management in Google Sheets, file organization, WordPress maintenance, visualization of sales and gross profit, simple reservation systems, Facebook ads, and more. The provider emphasizes “information design” and “organizing and structuring,” making it suitable for businesses that need help bringing order to messy data, workflows, and web-related operations.
The publicly listed price is 50,000 JPY per month, excluding tax. Contracts are generally signed in 3-month units, with automatic monthly billing; paying once every 3 months may also be negotiable. Supported payment methods include credit cards, Apple Pay, and Google Pay. The text notes that past work has averaged around 10 hours per month, but actual time may range from a few hours to 30–40 hours. As such, the service is better understood as ongoing support rather than a fixed-hours SaaS package.
The strengths are clear positioning, transparent pricing, and service coverage that matches the common digital chores of small shops. It is especially suitable for operators who cannot afford to hire a full-time web manager. The provider has experience in web planning, production, marketing, and online store operations.
The limitations are also clear: this is not a platform-style software product, and it does not disclose enterprise software indicators such as permission management, APIs, security compliance, SLA, or response times. It also explicitly states that graphic design and computer repair are not its strengths, and it is not intended for medium-sized or large companies.
RETZ is suitable for local Japanese small shops, e-commerce stores, physical retailers, and small business owners who need someone to handle ongoing remote tasks such as websites, advertising, spreadsheets, LINE accounts, and WordPress maintenance. It is not suitable for companies that require complex system integration, multi-account collaboration, strict compliance audits, or standardized software capabilities.
The text does not specify availability, network connectivity, or payment usability from mainland China, so these remain unknown. Apple Pay and Google Pay may also have limitations in the Chinese usage environment. Chinese users may consider alternatives such as local website maintenance outsourcing, WeCom service providers, Youzan/Weimob ecosystem service providers, digital marketing outsourcing agencies, or part-time web operations support.
