配送日指定.JP ‑ お届け日時・時間帯指定・置き配も対応

This Shopify app is presented as a fully free Japanese delivery date and time selection solution for merchants, covering major carriers such as Yamato, Sagawa, Japan Post, and Seino. It supports product-specific lead times, delivery company assignment, time-slot and leave-at-door options, estimated delivery displays, next-day shipping badges, customer-side date changes, and CSV export for order workflows, with placement options across cart, checkout for Shopify Plus, and thank-you pages. The app also emphasizes business-day calculations that account for prefecture-based delivery times, cutoff times, holidays, and closures, helping merchants show accurate delivery estimates and reduce lost sales, especially for stores with mixed product types or remote-area shipping needs.
