9 Shopify Shipping Apps for Japan Compared: Click Post, Yamato, Sagawa, Japan Post

Listings checked on: 2026-10-14 (each table row also carries a link to the listing page and the check date) Prepared by: The developer of "Instant Ship! for Click Post" (JizaiDev), based on a review of each app's listing page.

Because our own app is included in this comparison, we list only facts confirmed on the listing pages and do not rank the apps against one another.

Choosing by the Task You Want to Cut

The type of shipping app that suits you depends on which task you want to reduce. Based on the listing pages checked on 2026-10-14, it breaks down as follows.

• (a) Cut CSV preparation: CSV-export apps. For Click Post CSVs, the candidates with a mention on their listing pages are Click Post CSV File Download, Instant Ship! for Click Post, CSV Download (paid plan), and Delivery Manager (listed as also supporting Click Post).
• (b) Cut tracking number registration: Instant Ship! for Click Post extracts tracking numbers from the original Click Post PDF, and you review the suggested orders before registering them. Ship&co and Plus Shipping are listed as syncing or linking tracking numbers as part of issuing waybills in the admin.
• (c) Cut label (waybill) issuance: Direct-issue apps. Ship&co and Plus Shipping list Yamato, Sagawa, and Japan Post, and easyLabel lists Japan Post international shipping labels.
• The listing pages for these three direct-issue apps do not mention Click Post. The listing pages say nothing either way about support, so we could not confirm whether Click Post labels can be issued through a direct-issue app.

If you ship within Japan from Shopify, sooner or later you ask yourself, "Which shipping app should I actually install?" App descriptions alone make the differences hard to see, and it is difficult to judge whether one will suit your store.

So this article lines up 9 Shopify apps on four axes (pricing, features, supported carriers, and tracking number handling), using only what each app's listing page says.

How This Comparison Was Made

• We opened every app's Shopify App Store listing page (Japanese display) and checked it on 2026-10-14.
• The tables contain only what the listing pages say. Where a listing says nothing, we wrote "Not confirmed on the listing page". This does not mean "not supported". It means the listing page did not let us confirm it.
• Ratings and review counts are all the values on those same listing pages as of 2026-10-14.
• The 9 apps are those compared in the first edition of this article (2026-03-18), re-checked against their listing pages. This is not an exhaustive list of shipping apps for Japan.
• We did not install or operate any of the apps. This is an organized summary of listing-page statements, and the "Good fit when" notes are inferences from those statements.
• For Ship&co only, the listing page has no price table, so we also checked its official pricing page on the same day.
• Prices and plans change. Check the current details on each listing page before you install.

What to Look For When Choosing a Shipping App

Before looking at individual apps, here is how to think about what to choose on.

1. Supported carriers: Is Click Post enough, or do you also use Yamato, Sagawa, and Japan Post?
2. App approach: A CSV-export app, an app that extracts tracking numbers from the original PDF and registers them, or an app that issues waybills directly?
3. Tracking number handling: Is manual entry still required, or does the app help through to registration? Is there a review step before registering?
4. Pricing: The monthly fee, whether there is a free plan or free trial, and whether charges vary with volume.
5. Extra features: Delivery date and time selection, LINE notifications, CSVs for accounting software, and so on.

CSV-export apps versus direct waybill-issue apps: A CSV-export app turns Shopify order data into a CSV file that you upload to Click Post or a carrier's system. A direct waybill-issue app creates and prints the waybill from within the Shopify admin.

Shipping App Comparison Tables

We split the comparison into two tables. Each row has a link to the listing page and a check date (YYYY-MM-DD). The order follows the approach (CSV export first, then apps that issue waybills in the admin) and is not a ranking.

Table 1: Approach, pricing, free trial, and rating

About how prices are shown: "$" means billing through Shopify (USD). "Yen" refers to the yen-denominated amounts on the Ship&co and Plus Shipping listings. Ship&co's amount is listed as tax included, and Plus Shipping's 499 yen is listed as excluding tax. Ship&co and Plus Shipping are listed as possibly billing you separately from your Shopify invoice. A Ship&co subscription is set up from within your Ship&co account. Check each listing page for how exchange rates and taxes are handled.

Table 2: Supported carriers, Click Post, and tracking number handling

What "Not confirmed on the listing page" means: It marks an item for which we could not find a statement on the listing page. We have not concluded that it is unsupported. If an item matters to you, ask the app's developer.

App-by-App Details

We go through the apps in order of approach, laying out what each listing page says. The "Good fit when" notes stay within what the listing statements allow.

Click Post CSV File Download

Developer: dev.justbuild Pricing: Basic $5/month (7-day free trial) Approach: CSV export Listing page: Shopify App Store (checked 2026-10-14)

Converts orders you select from the order list into an editable CSV file in bulk. It detects and highlights fields that do not meet Click Post's requirements, such as the postal code format or address length. It also has a feature that automatically fills Click Post's "item contents" field from the order's products (you can edit it afterward).

Not confirmed on the listing page: Tracking number handling, support for carriers other than Click Post Good fit when: You only want to cut the effort of making Click Post CSVs

---

Instant Ship! for Click Post

Developer: JizaiDev (the publisher of this article) Pricing: Standard $8/month (10-day free trial). Japan Post postage is separate from the app fee Approach: CSV export + tracking number extraction from the original PDF and registration Listing page: Shopify App Store (checked 2026-10-14). The app is also introduced on its landing page.

It supports the two time-consuming parts of Click Post shipping: making the CSV and registering tracking numbers. The flow is as follows.

1. Select unfulfilled Shopify orders and create a Click Post CSV (1 to 40 orders per run). Addresses are split into 4 lines of up to 20 full-width-equivalent characters each. Text that does not fit at the end may be truncated. Characters Shift_JIS cannot represent may be replaced, and contents beyond the limit are cut. Check the downloaded CSV.
2. Importing the CSV, applying and paying, issuing and printing the label, and posting the item are all done by you through Japan Post's Click Post.
3. Load the saved original label PDF into the app to extract tracking numbers. If the PDF contains an order number, the app matches it exactly to the Shopify order name; if a postal code is also available, it checks that too. Without an order number, it finds candidates by postal code. Review the candidates and tracking numbers, select the intended order, and register the number.
4. Registration sends Shopify's shipping confirmation email. There is no setting to turn this notification off.

The PDF must be the original file downloaded from Click Post. Scanned PDFs and edited or merged PDFs are not supported. It reads 1 to 2 files per run (up to 10 MB each), up to 80 labels in total.

Out of scope: Click Post application, payment, label issuance, printing, and posting (you do these on the Japan Post side), carriers other than Click Post (not mentioned on the listing page), and re-registration to orders already fulfilled Order list range: The app displays the 250 newest unfulfilled orders. Unfulfilled orders older than 60 days can also be retrieved (developer reply in the Shopify App Store dated 2026-05-27; current implementation checked 2026-10-14). Confirm that the intended order appears before registering tracking. Good fit when: Click Post is your main carrier and you want to cut CSV preparation and tracking number registration. The effort of reviewing suggestions before registration remains About the rating: The rating is 2.0 (1 review). The review count is not large enough to judge a track record

Ship&co

Developer: Ship&co Pricing: Free to install. After the 30-day trial, a monthly infrastructure fee of 1,100–11,000 yen and a tiered fee of 22–10 yen per waybill apply, based on monthly volume (tax included). See the official pricing page. Approach: Issues waybills inside the app Listing page: Shopify App Store (checked 2026-10-14). Price table: official pricing page (checked 2026-10-14)

It is listed as supporting Yamato Transport, Sagawa Express, Japan Post, and Seino Transportation for domestic shipping, and FedEx, DHL, UPS, international mail, and others for overseas, and as issuing up to 50 waybills at a time. After issuing waybills, it also updates orders to shipped, syncs tracking numbers, and sends shipping notification emails.

On the official pricing page, the monthly infrastructure fee and the per-waybill charge are set in tiers according to the number of waybills issued in a month (all tax included). For example, the pricing page shows 35 waybills in a month as 35 × 22 yen = 770 yen, plus the 1,100 yen infrastructure fee, for a total of 1,870 yen.

Not confirmed on the listing page: Click Post support Good fit when: You want to issue labels for several carriers or for overseas shipments from one screen without CSVs. Because the fee changes as volume grows, check the pricing page's estimate against your own shipment count

Choosing by Approach: CSV Export, PDF Extraction and Registration, and Direct Issue

The approach bears directly on your daily work. Deciding first which task you want to cut makes it easier to narrow the candidates.

CSV-export apps

This approach turns Shopify order data into a CSV file that you upload to Click Post or a carrier's system.

• You can check and edit the CSV contents before uploading
• Applying, paying, and issuing labels are done by you in the carrier's system

The trade-off is that uploading the CSV is a manual step every time. Whether that feels like a burden depends on your shipment volume and how you organize the work.

Apps that extract tracking numbers from the original PDF and register them

Instant Ship! for Click Post is this type. After you make the CSV, it extracts tracking numbers from the original label PDF issued by Click Post, and you review the suggested orders and register them.

• It reduces entering tracking numbers into orders by hand, one at a time
• A step where you review the suggestions before registering remains
• Registration sends Shopify's shipping confirmation email (cannot be turned off)

Direct waybill-issue apps

This approach creates and prints waybills from the Shopify admin or inside the app. There is no CSV upload.

• Ship&co and Plus Shipping are also listed as syncing or linking tracking numbers
• Some pricing structures change with volume (such as Ship&co's official pricing page)

Do not decide on the monthly fee alone. Estimate the total cost at your own shipment volume before you decide.

Frequently Asked Questions

Are there any shipping apps I can use for free?

Four apps have a free plan or no monthly fee on their listing pages. Plus Shipping has no monthly fee, and only special shipping rates apply. Shipping & Order Supporter's free plan only covers adding fields such as delivery date and time selection, and CSV export starts with the Basic plan ($9/month). Japan Order CSV has a free plan of up to 100 orders per run and CSV Download has one of up to 50 orders per run, but carrier-specific formats are on the paid plans. For the other apps, the listing pages mention a free trial of the paid plan (for Plus Shipping, a trial period is not confirmed on the listing page).

Which apps support Click Post?

The apps whose listing pages mention Click Post are Click Post CSV File Download, Instant Ship! for Click Post, CSV Download (paid plan), and Delivery Manager. For Japan Order CSV, Shipping & Order Supporter, Ship&co, Plus Shipping, and easyLabel, we could not confirm a Click Post mention on the listing pages. That does not mean they are unsupported, so ask the developer if you need to know.

Which apps can cut manual tracking number entry?

The apps whose listing pages mention tracking numbers (waybill numbers) are Instant Ship! for Click Post, Ship&co, Plus Shipping, Delivery Manager, Japan Order CSV, and Shipping & Order Supporter (Pro plan). easyLabel only has "tracking" in a feature name, and the details are not confirmed on the listing page. The only app confirmed to handle Click Post tracking numbers is Instant Ship! for Click Post, which extracts them from the original PDF, and you review the suggested orders before registering. The review step remains. Ship&co and Plus Shipping are listed as syncing or linking tracking numbers as part of issuing waybills in the admin. Japan Order CSV lists "automatic waybill number reflection" and Delivery Manager lists "tracking number reflection", but whether they work for Click Post tracking numbers is not confirmed on the listing pages.

What should I base my choice on while my monthly shipments are still low?

The reliable way is to use an app with a free plan or free trial and see whether it actually reduces your work before deciding. The number of orders you can process in one run is 1 to 40 for Instant Ship! for Click Post's CSV, 50 for CSV Download's free plan, and 100 for Japan Order CSV's free plan. Because there is a cap on how many orders you can process at once, choose by comparing that with the number you want to process in a batch.

What should I watch out for in pricing as my shipment volume grows?

Check whether charges change with volume. For Ship&co, the monthly infrastructure fee and the per-waybill charge are set in tiers according to the number of waybills issued in a month. With easyLabel, going beyond the Lite plan's 100 labels per month adds $0.15 per label. Even apps with a fixed monthly plan have a cap on each export or run, so check the listing pages.

As of when is the information in this article?

It reflects what we saw when we opened each app's listing page (Japanese display) and Ship&co's official pricing page on 2026-10-14. Prices, plans, and ratings can change. Check the current details on each listing page before you install.

Summary

You can organize shipping apps on three points: whether the task you want to cut is CSV preparation, tracking number registration, or label issuance; whether you use only Click Post or several carriers; and how charges change as your volume grows.

Within the scope of this comparison, we did not confirm any single app that meets all of these needs. First decide which part of your work is the burden, and once you have narrowed the candidates, try them in this order.

1. Estimate the cost at your store's monthly shipment volume (for charges that vary with volume, check each company's pricing page)
2. Using a free plan or free trial, run a small test with a single real order
3. Check whether the task you wanted to cut (CSV preparation, tracking number registration, or label issuance) has actually been reduced, and decide whether to continue

We hope this comparison saves you the time of reading through each app's listing page one by one.
