This tutorial shows how to scrape Amazon Japan products from Amazon.co.jp keyword search results into CSV with the Amazon Japan Product Scraper template for UScraper. You will import the workflow, edit the keyword URLs, set the export path, run a dry test, and validate ASIN, rank, price, review count, rating, and page number before collecting more pages.
Before you start
Prerequisites and source checks
You need UScraper installed as a local desktop app, the free JSON template, one keyword you are allowed to research, and a folder where the CSV can be written. The bundled workflow is configured for the keyword wireless charger across pages 1 through 10, but your first run should use only one page.
This guide covers supervised collection from visible search result pages. It does not cover login-only pages, seller dashboards, checkout flows, account data, CAPTCHA bypassing, or resale of scraped data. Before automation, review the current Amazon.co.jp robots.txt and Amazon.co.jp conditions of use. If your project needs approved product-data access, compare this workflow with the current Amazon Product Advertising API or successor product-data documentation, including SearchItems and GetItems.
Technical access is not the same thing as permission. Keep the browser visible, avoid access-control bypassing, document why the data is being collected, and use official or licensed routes when the export will feed a production system.
Workflow shape
What the Amazon Japan product scraper does
The JSON export is the authoritative workflow definition. It sets the browser size, opens a list of known Amazon.co.jp search result URLs, waits for the page, checks for a validation form, waits for result cards, and then runs Structured Export against every non-empty search-result row.
{
"fileName": "amazon-japan-product-scraper.csv",
"input": "Amazon.co.jp keyword URLs, pages 1-10",
"rowSelector": "search result cards with non-empty ASINs",
"columns": [
"keyword",
"search_results",
"rank",
"asin",
"product_name",
"product_url",
"price",
"comment_count",
"rating",
"page_number"
],
"fileMode": "append"
}
Use the Amazon Japan Product Scraper as the download path rather than rebuilding blocks from this article. The template already includes the waits, selector logic, prompt branch, loop continuation, CSV filename, and append-mode settings.
| Export area | Columns | Validation question |
|---|---|---|
| Search context | keyword, search_results, page_number | Does the CSV row match the keyword URL and page shown in the browser? |
| Product identity | rank, asin, product_name, product_url | Can you open two product URLs and confirm the same ASINs? |
| Marketplace signals | price, comment_count, rating | Are blank cells explainable from the visible page state? |

How to scrape Amazon Japan products to CSV
Import the template
Open Amazon Japan Product Scraper, download the JSON, and import it into UScraper.
Edit the keyword URLs
In Navigate, replace wireless+charger with your approved keyword. Keep language=en_US only if that is the language context you want in the report.
Limit the dry run
Keep page 1 enabled first. Disable or remove pages 2 through 10 until the first export matches the browser.
Set the CSV save folder
In Structured Export, confirm amazon-japan-product-scraper.csv, headers, append mode, and a project-specific local save location.
Run and watch
Let the page load, handle allowed visible prompts manually, and stop if Amazon returns CAPTCHA, a robot check, or a page that is outside your permitted scope.
Validate before scaling
Compare ASIN, rank, product name, price, review count, rating, and page number against the browser before restoring pages 2 through 10.
Because the export uses append mode, clear old test files or change the filename before a production run. Otherwise, rows from earlier keyword tests can mix into the same CSV and make rank validation harder.
Validation
Common issues and fixes
Amazon.co.jp search pages are dynamic. Validation is not cleanup work after scraping; it is part of the scrape. Keep the browser open beside the CSV and inspect rows from page 1, a middle page, and the final page reached.
| Symptom | Likely cause | Fix |
|---|---|---|
| Zero rows exported | Product cards did not render, a prompt blocked the page, or the row selector no longer matches | Inspect the visible page, handle allowed prompts, increase waits, then rerun one page. |
Blank price | Amazon hid the offer, the product is unavailable, or the price module loaded differently | Treat price as optional unless it was visibly present for that session. |
Wrong rank | Amazon changed URL parameters or result-card indexing | Compare several rows and update rank logic only after confirming the page layout. |
Missing comment_count or rating | The card has no reviews, the module is hidden, or locale text changed | Keep the row and validate whether the field was visible on the source page. |
| Repeated rows | Append mode reused an old file or the same page URL was supplied twice | Start each keyword run with a clean CSV and dedupe downstream by ASIN and page number. |
Decision point
Amazon PA API vs scraping vs hosted tools
Use UScraper when the job is a supervised CSV export: one analyst, visible browser QA, editable workflow blocks, and a file saved to a local folder.
If you are comparing the best Amazon Japan scraper for a research workflow, start with data custody. UScraper keeps the run inspectable in a local desktop app. Hosted scrapers and APIs can be better for scale, but they usually move queries, pages, and outputs through a third-party runtime.
FAQ
Amazon Japan product scraping FAQ
Amazon.co.jp pages may be visible in a browser, but automated collection can still be restricted by Amazon terms, robots directives, anti-abuse systems, intellectual property rights, privacy law, and local regulations. Review the current source rules, avoid CAPTCHA or access-control bypassing, keep runs modest, and get legal review before commercial reuse.
