Japan Stationery Rankings & Prices (文房具ランキング) - Rakuten, Amazon JP, LOFT, MUJI, Hands, Itoya

Pick a stationery category (pens, notebooks, planners, office supplies, stickers...) and get the current Japanese bestseller rankings and prices from Rakuten Ichiba (楽天ランキング), Amazon.co.jp best sellers (売れ筋ランキング), LOFT (ロフト), MUJI (無印良品), Hands (ハンズ, formerly Tokyu Hands) and Itoya (伊東屋) in one table: rank, JAN code, maker (Pilot, Zebra, uni, Pentel, Kokuyo...), price in yen, sale flag, rating, review count and stock, plus rank and price change since your last run.

Built for buyers and resellers of Japanese stationery outside Japan, K-/J-stationery shops choosing what to import, and trend watchers who want to see which pens, notebooks and planners are selling in Japan this week.

What you get

• One row per product per list, the same columns for every store.
• Six Japanese sources in one run; a store that fails does not stop the others and is not charged.
• Rank and price tracking: each list is compared with your previous run (previousRank, rankChange, previousPrice, priceChange, isNewEntry, previousInStock).
• Changes-only mode: outputMode: changesOnly saves (and charges) only products that are new in the ranking or whose rank, price or stock changed. Ideal for a daily schedule.
• Maker detection in English (maker), so "三菱鉛筆", "uni" and "ジェットストリーム" all become Mitsubishi Pencil (uni).
• Names are NFKC-normalized (full-width "０．５ｍｍ" becomes "0.5mm"), text stays in Japanese.

Sources

source	What is read	Order / rank	Depth	Notes
rakuten	Rakuten Ichiba genre ranking (daily, weekly or realtime)	Rakuten rank	up to 1,000	Names are shortened by Rakuten (end with "…"). Rating is the star display (0.5 steps). Shop name included, sourceRankTrend = up/down/same/new from Rakuten.
amazon	Amazon.co.jp best sellers (文房具・オフィス用品 and sub-categories)	Amazon rank	100	ASIN, rating, review count, lowest offer price ("from" price when several sellers).
loft	LOFT net store ranking (ステーショナリー)	LOFT rank	40 (overall stationery ranking: 10)	JAN, brand, LOFT category, sale and LOFT-limited labels. A few seasonal rankings (e.g. 手帳) are shown without rank badges; then rank is the page position and RUN_SUMMARY has a warning.
muji	MUJI net store section in best-selling order (売れ筋順)	position	whole section	JAN, sale price and old price, stock.
hands	Hands net store category list (store's recommended order)	position	whole category	JAN, rating, reviews, net-store stock (inStock / lowStock / outOfStock). Uses a Japanese residential proxy automatically.
itoya	Itoya online store category, newest first	position	whole category	JAN, brand, price, out-of-stock tag.

listType is ranking for real rankings (Rakuten, Amazon, LOFT, MUJI best-selling order) and categoryList for Hands and Itoya (their sites have no public ranking list; rank is the position in the list).

Main fields: source, sourceName, listType, rankingName, category, categoryId, period (Rakuten), rank, productId, janCode, asin, itemCode (Rakuten shop:item), name, brand, maker, shopName (Rakuten), productCategory (LOFT), price, priceIsFrom, originalPrice, isOnSale, labels, rating, reviewCount, inStock, stockStatus, sourceRankTrend, imageUrl, url, previousRank, rankChange (positive = moved up), previousPrice, priceChange, priceChangePercent, previousInStock, isNewEntry, previousScrapedAt, listUrl, scrapedAt. Missing values are null; every row has every field.

A RUN_SUMMARY record in the key-value store lists each source and list with status (completed, partial, failed, budgetLimited), the stop reason and the number of products saved.

Pricing

Pay per product row saved (event product). Lists that fail and products skipped by changesOnly are free. When your "Maximum cost per run" is reached, the run stops cleanly with the message "Stopped at the maximum cost per run" and keeps everything saved so far.

Notes and limits

• Prices are the yen prices shown on each store (tax included). Amazon prices are the lowest offer shown in the ranking; Rakuten prices are the shop's price ("from" when the item has variations).
• Rating and review count are not shown by LOFT, MUJI and Itoya lists (null).
• janCode is filled only when the store's product code is a valid JAN (EAN-13). Amazon rows have the ASIN instead.
• Hands answers only Japanese IPs. The Actor uses Apify's RESIDENTIAL proxy with country JP for Hands automatically. If your plan has no residential proxy, Hands lists fail (free) and the other sources still run.
• Only public product lists are read; no login, no personal data. The Actor never solves captchas: if a store shows a robot check, it retries with a new IP and otherwise reports that list as failed.
• Store layouts change; if a source stops returning rows, please open an issue.
