Knowledge
How to read procurement data, how to use Hashike's own features, and practical workflows that combine the two with AI tools. Every article that carries a figure states the population and source behind it.
Guides
Step-by-step explanations of how to get a specific task done.
Research what a US agency buys in Japan
Hashike lets you filter US federal notices performed in Japan by buying agency (Navy, Army, Air Force, State and others) and read them in Japanese. For past contracts, the us_buyer_profile tool returns each agency's award count, value and contracting-office breakdown.
Look up a company's government award record by 法人番号
Hashike's company pages use the 法人番号 to show what one company won from Japan's central-government ministries over the most recent 60 months: award count, value in yen, buying ministries and recent awards, all from public 調達ポータル records.
AI workflows
Practical ways to combine Hashike's data or API with an AI tool.
Check the figures in an AI's procurement analysis against the source data
When ChatGPT or Claude analyzes procurement data for you, keep the Hashike data you gave it and match each figure in the answer to the original value, unit, records counted and period; that is how you confirm the figures are right.
Analyze a Hashike market brief with Claude
Export the market brief on a Hashike notice page as Markdown and give it to Claude, and you can ask questions about past US federal contracts with the sources, populations and limits still attached. You then check each figure in the answer against the section of the brief it came from.
Narrow a shortlist of Japanese government suppliers with AI
Pull one ministry's award results from Hashike over MCP, have an AI assistant group them by corporate number into a candidate list, then check each candidate's count and value against the figures Hashike returned.
AI prompts
Reusable prompts you can copy and run as they are.
A prompt for reading a ministry's buying pattern with an AI assistant
An English prompt that has an AI assistant read one Japanese ministry's award results from Hashike's buyer_profile (a rolling 60-month window) and report scale, contract methods, repeat purchases, supplier concentration and timing without departing from the source figures.
MCP tutorials
How to call Hashike's MCP server from an actual client.
Pull a comparable-market analysis by NAICS code with research_brief
Give Hashike's research_brief MCP tool a NAICS or PSC code and your AI assistant receives a comparable-market analysis of past US federal contracts performed in Japan: award-value distribution, reported offers, supplier and buyer concentration, demand frequency and data quality.
Look up a supplier's award history by 法人番号 over MCP
Pass one corporate number to Hashike's supplier_profile tool and it returns, over MCP, that company's Japanese central-government award count and value, the ministries that bought from it, its contract methods and its recent awards.
