Scrapes listing data from Jmty (ใธใขใใฃใผ), Japan's dominant hyper-local classifieds and flea-market platform. Not Mercari โ the other one, the one with free giveaways, local lessons, and listings for things you'd never think to search for nationally.
Returns structured records per listing: title, price, location (prefecture + city), category hierarchy, full description, seller info, image URLs, and timestamps. All fields sourced from the site's Next.js data layer, not scraped from CSS selectors.
What It Covers
Jmty's URL pattern is /{prefecture}/{category}. You configure which prefectures and categories to scrape; the actor paginates through all results and pulls a detail page per listing. Default scope is Tokyo โ sale. Scale to all 47 prefectures or specific subcategories as needed.
Top-level categories: sale, lesson, event, job, community.
Subcategory examples: sale-ele (electronics), sale-fur (furniture), job-off (office work), lesson-mus (music lessons).
Input Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
maxItems | integer | 10 | Maximum listing records to return. Omit for unlimited. |
prefectures | array | ["tokyo"] | Prefecture slugs (e.g. tokyo, osaka, kanagawa, aichi). |
categories | array | ["sale"] | Category or subcategory slugs to scrape. |
Output Schema
Each record contains:
| Field | Type | Description |
|---|---|---|
listing_id | string | Short listing key used in the URL (e.g. lc6o4) |
title | string | Listing title |
category | string | Top-level category name in Japanese |
category_en | string | Category slug in English (e.g. sale) |
subcategory | string | Subcategory name in Japanese (e.g. ๅฎถ้ป) |

How It Works
Listing pages (/tokyo/sale, /tokyo/sale/p-2, etc.) are server-rendered HTML. The actor reads li.p-articles-list-item elements to find detail page URLs. Detail pages are Next.js SSR โ structured data lives in a __NEXT_DATA__ JSON block, parsed directly without a browser. No JavaScript execution required.
Concurrency is kept low (3 parallel requests) out of courtesy. The site has no anti-bot protection.
Pricing
Pay-per-event. Charged per listing record returned. No charge for pagination pages or failed requests.
