MUJI Scraper - Products, Prices, Stock & Reviews

MUJI Scraper: Prices, Stock, Discounts and Reviews

MUJI Scraper turns MUJI's United States, Canada and Australia storefronts into structured product data. Every product comes back as one flat record with its identity, price and discount, per-variant stock, sizes and colours, images, the full description with materials and country of origin, and its customer rating and reviews. Search by keyword or paste product, category and search links, then export to JSON, CSV or Excel, or pull the results straight into your app through the API.

Why This Scraper?

• Three country storefronts, one actor. Search by keyword or paste links for the United States, Canada or Australia; each keeps its own country, currency, prices and stock, and links from different countries can be mixed in one run.
• A full pricing picture. Current price, was-price, discount amount and discount percentage, plus per-variant stock and backorder status.
• Deep detail on demand. Full description, breadcrumb, extra media, materials, measurements, care notes and country of origin, toggled per run so you only pay for what you use.
• Customer voice. Individual reviews with rating, title, text, author, date, verified-buyer flag, helpful votes and photos, plus the per-star breakdown, where the storefront publishes them.
• The storefront's own filters. Category, colour, size, price range and availability, matched to each storefront's own values so spelling and capitalisation are handled for you.
• Five ways to order results. Relevance, price, name, newest or best selling.
• Built for schedules. Incremental mode returns only new and changed products on recurring runs, and a refused run fails loudly instead of returning an empty dataset.

Use Cases

• Price and discount tracking: monitor was-price, discount percentage and stock across a catalogue on a recurring schedule.
• Assortment comparison: compare category, pricing and stock across the US, Canada and Australia storefronts.
• Product research and cataloguing: pull full descriptions, materials, measurements and media for a product line.
• Review analysis: collect individual customer reviews and ratings to track sentiment on top sellers.
• Competitive and catalogue monitoring: watch a category or search result for new arrivals and price changes.

How to Use

1. Pick a mode: search (by keyword) or url (paste MUJI links).
2. Pick a country storefront (us, ca or au) and any filters: category, colour, size, price range or in-stock only.
3. Turn on Fetch product details and Fetch customer reviews for the deeper fields, or leave both off for a lighter, listing-only run.
4. Set Max products and Max pages to control run size and cost, then click Start.

Keyword search on the Canadian storefront:

{
  "mode": "search",
  "queries": ["aroma diffuser", "essential oil"],
  "country": "ca",
  "maxItems": 40
}

Discounted products from a category link, cheapest first:

{
  "mode": "url",
  "urls": ["https://www.muji.us/collections/sale"],
  "sortBy": "price_asc",
  "maxItems": 100,
  "maxPages": 0
}

Filtered search with reviews:

{
  "mode": "search",
  "queries": ["shirt"],
  "country": "us",
  "category": "T-Shirts",
  "color": "Black",
  "minPrice": 20,
  "maxPrice": 60,
  "inStockOnly": true,
  "fetchDetails": true,
  "fetchReviews": true,
  "maxReviewsPerProduct": 25
}

Supported link shapes. If you leave the links empty in URL mode, the run now scrapes the 11 example links below (one per shape, each a distinct target) instead of nothing.

Shape	Example
Collection	https://www.muji.us/collections/aroma-fragrances
Product	https://www.muji.us/products/ultrasonic-aroma-diffuser
Search	https://www.muji.us/search?q=diffuser
Collection from page N	https://www.muji.us/collections/aroma-fragrances?page=2
Sorted collection	https://www.muji.us/collections/aroma-fragrances?sort_by=price-ascending
Filtered and sorted collection	https://www.muji.us/collections/aroma-fragrances?filter.v.price.gte=20&sort_by=best-selling
Product under a collection	https://www.muji.us/collections/aroma-fragrances/products/scented-glass-candle-travel-ocd1cc1a
Product .json link	https://www.muji.us/products/fragrance-candle-gardenia-ocz6cc4a.json
Store without www	https://muji.us/collections/acrylic-storages
Canada, all products	https://muji.ca/collections/all
Australia search	https://muji.com.au/search?q=shirt

A link's own sort_by, filter.v.price.gte, filter.v.price.lte and filter.v.availability are honoured for that link and win over the form for it. Any other filter.* key, and /pages/, /blogs/, MUJI Japan and MUJI Europe links, are skipped with a warning that says why. A run that starts at page=N or uses a link filter covers only part of the catalogue, so it never marks other tracked products as expired. If a category, colour or size name is not in the storefront's own list, the log warns and lists the names that are.

Links from three countries in one run:

{
  "mode": "url",
  "urls": [
    "https://www.muji.us/products/ultrasonic-aroma-diffuser",
    "https://muji.ca/collections/sale",
    "https://muji.com.au/search?q=oxford+shirt"
  ],
  "maxItems": 60
}

Run it from your code

Python:

from apify_client import ApifyClient

client = ApifyClient("<YOUR_APIFY_TOKEN>")
run = client.actor("abotapi/muji-scraper").call(run_input={"mode": "search", "queries": ["aroma diffuser"], "country": "us"})
for product in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(product["title"], product["price"])

JavaScript:

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: '<YOUR_APIFY_TOKEN>' });
const run = await client.actor('abotapi/muji-scraper').call({ mode: 'search', queries: ['aroma diffuser'], country: 'us' });
const { items } = await client.dataset(run.defaultDatasetId).listItems();

Or connect it to Make, Zapier, n8n, Google Sheets or webhooks from the Integrations tab.

How Max products and Max pages cap a run

maxItems is the run's only cap by default (0 for unlimited). With several keywords or links it is split evenly between them, so one busy search cannot crowd out the rest. maxPages limits result pages per keyword or link and is unlimited unless you set it, so it never caps a run below maxItems. A category or search link that already carries page=3 starts at page 3 rather than page 1.

Resume and recurring updates

Two separate features, for two separate jobs.

• Resume (resumeFromRunId) continues one interrupted run: paste its run or dataset ID and the actor skips every product it already collected there, so nothing is collected or billed twice.
• Incremental mode (incrementalMode) is for running the same search again and again, for example on a daily schedule. The first run returns every matching product as NEW. Later runs return only what changed: UPDATED (with changedFields), REAPPEARED, UNCHANGED (suppressed and not billed unless emitUnchanged is on) or EXPIRED (only after a run that scanned the whole tracked search, and only with emitExpired). stateKey names or shares the stored state; leave it empty to derive one automatically from the storefront, search and filters, so two different searches never mix. Changing changeScope or ignoreFieldsForChanges never restarts the baseline: stored products are compared again under the new setting, so no product comes back as NEW or is billed again because of it. A product is UPDATED when a stored field moves (price, was-price, promo, stock including per-variant stock, copy, images, options); review text, ratings, review counters and the scrapedAt and updatedAt timestamps never count and are still returned in every row (a live double scrape of 50 products found no other field that moves between two scrapes of the same product). changeScope set to price and stock only narrows this to price, was-price, discount, on-sale, in-stock and each variant's price and availability. ignoreFieldsForChanges adds your own field names, or dotted paths such as variants.image. compactUpdates slims UPDATED and EXPIRED rows to identifiers, current price and stock, priceChanges and variantChanges; a compact row carries no product details, so no detail-enrichment charge applies to it. expireAfterMissedScans waits for that many consecutive complete scans before a product is marked EXPIRED; EXPIRED means the product dropped out of the scanned search, not necessarily that it is out of stock.

Output views

The dataset has four tabs in the Console. Products is the overview with price, discount, stock and rating. Product details adds description, materials, measurements and origin. Reviews lists one row per customer review. Changes (incremental mode) shows changeType, changedFields, priceChanges and variantChanges. Every view reads the same records, so exports from the API are unchanged.

What you are billed for

• Actor start: one apify-actor-start event per run.
• Result: one apify-default-dataset-item event per product row pushed to the dataset. Suppressed UNCHANGED rows are not pushed and are not billed.
• Detail enrichment: one detail-enrichment event per pushed product for which details or reviews were collected, and none for compact UPDATED and EXPIRED rows. A pasted product link always returns full detail, so it carries this event.

The Pricing tab shows the current rates. Max products caps the cost of a run.

Send results into your apps (MCP connectors)

Optionally pipe the scraped results into the apps you already use, via Model Context Protocol (MCP) connectors. This is an extra delivery step after the scrape: the Apify dataset is never changed.

What gets written to the connector: a condensed, human-readable summary of each product, not the full record. Each item becomes one entry with a title and its key fields flattened to plain text. The complete record always stays in the Apify dataset.

1. Authorize a connector once under Apify, Settings, API and Integrations (Notion, Linear, Airtable, or Apify).
2. Select it in the "Pipe results into your apps" input field. If the picker is empty, you have not authorized a connector yet.
3. For Notion, also set notionParentPageUrl to the page where product pages should be created.

The connection is mediated by Apify's MCP proxy, so this actor never sees your third-party credentials. maxNotifyListings caps how many products are written per connector and never affects the dataset. Leave the field empty to skip.

Plan Requirement

Apify Proxy is used by default, with the connection chosen for you. The default Apify datacenter connection reads all three MUJI storefronts (United States, Canada, Australia), so the actor works with no proxy setup on a plan that includes Apify Proxy. Slow or failed pages are retried on a fresh address of the same connection; a slow page, a server error or an unexpected reply never moves the run to another connection. Only when the platform itself refuses the connection (it answers the connect request with 403 or 407) does the actor switch to a backup connection. When that happens the log says: "The selected connection is unavailable to this run. Apify free plans do not include residential proxies. Continuing on a backup connection; some pages may still be unavailable." and later "Served over the backup connection (the default connection was unavailable)."

If no page can be loaded the run ends as failed with one of these messages, instead of returning an empty dataset:

• The proxy connection was refused for this account (your plan has no proxy access, or your own proxy URLs have invalid credentials).
• Residential proxies are unavailable on this run and the backup connection could not load the requested MUJI pages.
• No results page could be loaded because the requests failed; this is a connection problem, not an empty search, so try again later.

Your own proxy URLs are used as given, with no backup connection. Each product page is given a limited time window, so one stuck page cannot stall the whole run.

FAQ

How much does it cost?

You pay per product returned, plus one detail-enrichment charge per product for which details or reviews were collected. A pasted product link always returns full detail, so it carries that charge even with both toggles off; any other run with both off is charged per result only. The Pricing tab shows the current rates, and Max products caps the cost of any run.

Is it legal to scrape MUJI?

This actor collects only publicly available product data. You are responsible for how you use it: follow MUJI's terms and the laws that apply to you, and get legal advice if you plan commercial redistribution. Product descriptions, prices and stock are generally facts, but photos and some copy may be subject to third-party rights.

Can I get only new or changed products on a schedule?

Yes. Schedule the actor from the Schedules tab and turn on Incremental mode. Each run then returns only new and updated products, and unchanged ones are not billed. stateKey lets you name a monitoring campaign so its state stays stable across runs.

Why does a category or search link sometimes return fewer products than expected?

The run stops at Max products, or at Max pages if that is set lower. Raise either one, or set it to 0, to collect more of a large category.

Why did my run fail instead of returning an empty dataset?

If the storefront refuses every request, the run stops with a clear message so "no matching products" is never confused with "nothing could be read". Run it again in a few minutes. If only some links or pages could not be read, you still get what was found.

Can I use it with AI agents or MCP?

Yes. Call it from any Apify integration or MCP client, and use the connector field to push results into Notion, Linear or Airtable.
