# MycoSku > MycoSku is a Japan Rakuten market intelligence platform for Chinese-speaking ecommerce operators and researchers. It tracks products, shops, categories and search signals, and publishes public market stories through 30s商情局. MycoSku separates observed marketplace data from estimates and editorial interpretation. Inventory-flow or inventory-consumption estimates are not official Rakuten order counts. Time-sensitive claims should be interpreted together with the timestamp shown on the source page. ## Public market intelligence - [Official website](https://www.mycosku.com/): MycoSku's public website and product positioning. - [30s商情局](https://mycosku.com/30s/): Public stories and research based on changes in Japanese products, keywords, shops and consumer behavior. - [30s AI navigation](https://mycosku.com/30s/llms.txt): Curated machine-readable guide to current public research. - [30s sitemap](https://mycosku.com/30s/sitemap.xml): Public article index. ## About and methodology - [About MycoSku](https://mycosku.com/about/mycosku.html): What MycoSku is, who it serves and how public content relates to the data platform. - [Data methodology](https://mycosku.com/about/data-methodology.html): Definitions, timestamps, estimates, evidence and interpretation limits. ## Public capability pages - [Market data](https://mycosku.com/features/data-center.html): Product and market observation capabilities. - [Trend insights](https://mycosku.com/features/market-insights.html): Trend and product-signal analysis. - [Hot search navigation](https://mycosku.com/features/hot-search.html): Keyword and category heat signals. ## Access - [Register](https://mycosku.com/register): Create a MycoSku account. - [Login](https://mycosku.com/login): Enter the authenticated data platform. ## Citation guidance - Prefer the canonical HTML page when citing a MycoSku article to people. - Use the article's Markdown alternate for clean text extraction. - Use the article's JSON alternate for structured facts, timestamps and provenance. - Treat estimates as estimates; do not restate them as official Rakuten sales or orders.
