UK Fulfillment by Merchant on Amazon Japan


If your product is relatively small and light then using the Fulfillment by Merchant option to sell your UK products on Amazon Japan is a viable option. Basically it is the same as posting to a location in the UK, except with a few important differences.

Posting from the UK to Japan

If you have chosen Fulfillment by Merchant on Amazon Japan then when someone places an order you will get a notification within your Amazon Japan dashboard (and also by email if you have email notifications set up).

Fulfilled by Merchant notification

Clicking on the ‘Unshipped’ tab will open up the order information, as shown in the screenshot below.

The first thing you need to do is select ‘Print packing slip’ and then print off the packing slip details. The top section is the address so you can cut this off to stick onto your packaging (Jiffy bag, box etc.). Of course this is all in Japanese, so you should write ‘JAPAN’ on to the address label.

Shipping to Japan from UK

When sending from the UK to Japan you need to complete a customs sticker and stick this to the package. The Post Office gives you this customs sticker and it is a simple process. The easiest option is to check the ‘Gift’ checkbox and put in a simple description of what the product is. Ours was a glasses lens, so we put ‘Glasses lens’. Put in an approximate value of the product in the ‘Value’ section. If your product is over £20 the Post Office will offer you some kind of cover/insurance postage option. It is up to you if you choose this. We generally do not for our product that sells for 4999 Yen (approx. £35).

NOTE: We charge postage on top of this 4999 Yen, so you need to figure out if your customers are willing to pay for this extra cost. Using FBA means Prime customers not only get next day delivery but it is also free. This is an obvious advantage and will increase sales.

Sign the customs slip at the bottom and stick it to the package. The final thing to do is to write your name and address onto the package in case it needs to be returned to you.

That’s it, hand it over at the Post Office and they will send it off. They may ask for some address details for your receipt, but all they will need is the ZIP / Post Code which is generally the top numeric code on the address slip. Also they tend to ask for house number, which is on the address slip. If you do not provide this information they can still post it, but it means it will be harder for you to dispute a failed or damaged delivery.

Don’t forget to mark your order as sent! – After you post your product off to Japan head back to your Amazon Japan dashboard, click on the ‘Unshipped’ link and select ‘Confirm shipment’. Make sure you confirm the shipment because if you do not two things happen:

  1. You don’t get paid
  2. Amazon gives you a black mark for not posting quick enough

You need to make sure Amazon looks at you as a good seller, so getting black marks against your account can mean it does not value you as a trusted seller and this can affect your listing and account performance. Make sure you post your item quickly and then mark it as sent in your account.

Time and cost of posting to Japan

For our small package it costs £4.45 to post to Japan and takes about 7 days. We are lucky that our product is very niche and there is minimal competition on Amazon Japan. Therefore customers are willing to wait 7 days. If there was higher competition then we would use Fulfillment by Amazon (FBA), which is what we do for another product we sell – This product here.

FBA means that you store your products in Amazon warehouses out in Japan and then if someone orders your product Amazon handles all packaging and postage. It also means you do not have to worry about sending things off quickly or updating your account to mark as sent. Amazon takes care of everything.


Amazon Fulfillment by Merchant from the UK to Japan is definitely an option for a lot of UK sellers. In fact if your product is small and light enough it is a good way to test the waters in the Japanese marketplace. However, for larger products or when you are selling higher numbers of products then Amazon Japan FBA is a better option.

Our office is located close to a Post Office but it still took 30 minutes in total to walk over there and post the product off to Japan. There was also the printing of the packing slip and packing preparation to add to this. Because this product is a relatively new test sample we are willing to do this, but as sales increase we will send a larger batch out to Japan and store them in the Amazon Japan warehouses and use FBA.

Storing in Japan also allows buyers to choose Amazon Prime next day delivery, which not only means they get their order the very next day but it also means they get it delivered free if they have Prime. This undoubtedly increases sales over non Prime products on Amazon Japan.

If you are currently using Fulfillment by Merchant and want to start using FBA in Japan then get in touch. We can help ship your products into Japan warehouses.

The Rising Sun Commerce Amazon Japan Product Listing Process:


We gather all the information needed to fully understand your product and brand. We need to understand your products' features and benefits in fine detail so that we can hone the copy of your listing. We can use your English Amazon listings as a guide, however Amazon Japan is VERY strict in the wording you can use and often your English listings would be rejected instantly.


We conduct detailed keyword research using specialist software such as Helium10’s Cerebro tool to analyze the keywords used by your main competitors on Amazon Japan. We also use Amazon’s own Brand Analytics data to ensure we pull out all of the most important keywords. Finally, we manually read over your competitors listings to pick out common keywords.


Our optimally written product listings are professionally translated by one of Rising Sun Commerce’s experienced native Japanese listing editors who carefully integrate the keywords from the extensive keyword research process as they translate your product listings - check out Shiori’s short video where she discusses a client's listing here.


We annotate any text in your images into Japanese, because everyone knows that the images are one of the most important aspects of your Amazon Product Detail Page.


We construct an upload (AKA flat) file and upload your listings to Amazon Japan. We complete as many fields as possible in the flat file to help with Amazon indexing and categorisation. We apply any keywords that are not integrated into the product listing into the Generic Search Terms (AKA back end search terms). Uploading the flat files to your Amazon Japan account can sometimes be a smooth process, but due to Japan’s quirks and glitches this can often be a bumpy process. We guarantee that your product listings will be uploaded to Amazon Japan, even if it takes multiple Seller Support cases and multiple revisions to remove and replace text or images to satisfy the Amazon Japan gods.


We upload your Japanese specific images to Amazon Japan. This can be a complex process and often requires multiple attempts and Seller Support cases. It also requires Brand Registry access so there is additional admin required.


Any appropriate listing videos will be annotated and/ or a voice over will be applied at no extra cost. The videos will be uploaded to your listings.


Using your English A+ content as a guide we construct and upload A+ content for your product listings. Like the Product Detail Pages this can often be a tough process because Amazon Japan are irrationally picky about the words you can use. We have a database of banned words and phrases, but we are still surprised by Amazon when they pick up on a new term. Again, we guarantee your A+ content will be uploaded to Amazon Japan, no matter how long it takes.


Finally, once the listing has been on Amazon Japan for a few days we do Keyword Index Checks to make sure the listings are correctly indexed.

Watch the video below of Shiori (one of our expert editors) discussing her translations for a clients product.

The video below show how we make sure your products are fully indexed on Amazon Japan.


Using one of our trusted native Japanese creators we can commission custom unboxing videos for your products.

We ensure the creators discuss the main benefits and features of your product.

Alternatively, if you have a good promotional video in English, we can replace the English voice with a professional standard Japanese voice.

Having a video on your Amazon Japan product listing is a major benefit and helps show the shopper exactly what they will get and reinforces the main product selling points.
