Data Bin is a Japanese browser-based file-sending service where users upload large files and deliver a download URL to recipients. After uploading, the service can email a notification, or the sender can share the link through their own email or chat app. Upload settings include an expiration period, download password, download-completion notice, and upload-completion notice, with an optional secure-delivery feature. Capacity and features vary by plan, and the homepage lists a 2 GB limit for the Light plan. The site also explains its guides, pricing, FAQs, contact options, security feature, and business plans.
