Checking Rakuten prices by hand means opening the same listings over and over, hoping you catch the drop before the deal is gone. This Actor watches for you. Give it search keywords in Japanese or English, run it on a schedule, and get a clean feed of price drops, restocks, and rating changes, nothing more. Works out of the box, no account or setup required.

🔍 What does Rakuten Price Monitor do?

Give it search keywords to watch, in Japanese or English. On each scheduled run, it checks the current search results and compares them to what it saw last time. By default it hands back only the items whose price or stock status actually changed, so you are never re-reading the same unchanged rows. It tracks price, in stock or out of stock status, review score, and reward points for every item.

💡 Why use it?

"I resell imported goods sourced from Japan. I watch a list of keywords every morning so I can reprice the moment a supplier drops a cost."

"I hunt deals on Rakuten for hobby items. I keep a wishlist of search terms and this tells me the day a price actually falls, instead of me checking by hand."

"I do import and arbitrage work between Japan and other markets. I need to know Japanese prices before a competitor does, so a daily changed-only feed is exactly what I track margins with."

"I run a shop on Rakuten myself. I watch my own shop's name as a search term so I notice instantly if a listing goes out of stock or a price gets changed by mistake."

✨ Tips

• On your first run, turn "only changed" off once to capture a full baseline snapshot of every item.
• Watching a shop's own name as a keyword is a good way to catch a competitor's repricing or restocking before anyone else notices.
• Pair a daily schedule with Google Sheets to build a running price history without touching a spreadsheet by hand.
