ポイカン is a cashback comparison service for Japanese “ポイ活” users. It aggregates publicly available cashback information from multiple ポイントサイト and ad campaigns, helping users compare rewards across different channels before shopping or participating in promotions. The site states that it covers 143 services and lists more than 380,000 items, including campaigns related to common shopping platforms such as 楽天市場, Yahoo!ショッピング, Amazon, メルカリ, Qoo10, Temu, and AliExpress.
Functionally, ポイカン is not a traditional SEO tool, but rather a horizontal comparison tool for cashback and affiliate shopping information. It can display current “latest” rewards, “ended” campaigns that have not been confirmed for more than 24 hours, and “past highest” cashback rates recorded since the system refresh in May 2021. Cashback amounts are calculated based on official information from each points site, converting base awarded points into an equivalent yen value and displaying the rounded result.
In terms of data sources, the platform mainly collects public information from various ポイントサイト and advertising providers. Its system automatically retrieves and updates data multiple times per day, supplemented by engineer management, manual checks, and corrections. Rankings are generated automatically based on the collected listing data, and the site explicitly states that rankings are not adjusted based on advertising fees. This is an important credibility factor for a cashback comparison platform.
ポイカン is completely free to use, with no membership registration required and no additional fees. For regular users, the barrier to entry is low, making it suitable for quickly checking which points site offers higher cashback before placing an order. The text does not mention an API, browser extension, mobile app, enterprise dashboard, or marketing-system integrations, so it is more like a public lookup website than a SaaS product for corporate marketing teams.
Its strengths are that it is free, has a large data set, updates frequently, and explains its data methodology. The main limitation is that cashback information may still differ from actual conditions due to advertiser campaign changes or update delays, so users should ultimately confirm details on the official points site. Some smaller sites or non-public offers may also not be included. It is suitable for individual consumers in Japan, heavy cashback users, and shopping-guide content operators who want to reference cashback trends. It is not well suited for SEO rank tracking, keyword research, or enterprise advertising management.
The crawled text does not provide information about access from mainland China, payments, or language support, so its accessibility from China is unknown. Since the content mainly focuses on Japanese points sites and Japan’s e-commerce ecosystem, even if Chinese users can access it, its practical value depends on whether they participate in Japanese shopping cashback programs. For users focused on local Chinese cashback or shopping-guide platforms, 淘宝联盟, 京东联盟, 什么值得买, and similar services may be more relevant to local payment and e-commerce environments.
