The agent successfully assembled a comprehensive profile of Hareruya as Japan's largest MTG retailer and tournament operator with international reach, but encountered a navigation gap: specific pricing and shipping costs were not exposed on public English-language pages, and the Help section returned a 500 error, forcing reliance on contact information and model inference to explain what could not be retrieved.

• ›Site discovery required web search (60% of URLs) and memory-typed URLs rather than on-site navigation; the initial direct fetch failed with ECONNREFUSED, suggesting DNS or connectivity issues with the root domain or routing rules favoring the /en/ path.
• ›The English-language pages ([2] and [3]) provided operational and positioning information (inventory depth, tournament hosting, international shipping) but no pricing tables, product costs, or shipping rate details—these appear to exist only in Japanese or behind product-level clicks not traversed by the agent.
• ›The Help page ([4]) returned HTTP 500, blocking access to what would likely be the canonical source for shipping, pricing, and policy FAQs—a critical usability gap for international customers evaluating the service.
• ›The article subdomain ([5]) was agent-discoverable via search and provided mission and history context (Saito's founding philosophy, Hareruya Pros/Hopes programs) that differentiated the brand but was not surfaced by the main shop domain, requiring external search to fill gaps.
• ›Site content was fragmented across domains (hareruyamtg.com shop, article.hareruyamtg.com blog) with no apparent internal linking between them, making agent-driven discovery difficult without prior knowledge or search supplementation.
