5 Common Mistakes eCommerce Brands Make When Entering Japan

Many international eCommerce brands that try entering Japan are convinced the country is going to be their next success story. This is often due to a strong sense of confidence based on past overseas expansion experience, proven products, and established strategies.

However, while a history of success in other markets can provide a strong starting point, it can also create expectations that do not fully reflect how Japan works. Based on COVUE’s experience, there are five common Japan eCommerce entry mistakes that often cause problems for e-commerce brands entering Japan.

Believing You Already Understand the Japanese Market

One of the easiest mistakes to make is entering Japan with more confidence than evidence.

A company may have a product that fits an existing market category, have an established eCommerce operation abroad, perhaps even have received encouraging interest from a local partner, or already be fulfilling orders to Japanese consumers from overseas.

The problem begins when these signals are treated as proof that the company’s product and marketing are ready for a Japan launch.

We saw this in the past with a brand planning to introduce shower stools in Japan. The company saw what appeared to be a natural opportunity because shower stools were already common in Japanese bathing culture, while relatively few products on major marketplaces looked directly comparable to their own.

However, pre-launch research identified a basic product-fit issue. The company’s stools were considerably larger than the compact designs commonly sold in Japan, making them less suitable for many Japanese bathrooms and established bathing habits. What initially looked like a gap in the market was therefore much narrower than expected, and the absence of directly comparable products was not necessarily evidence of unmet demand, but rather a sign that local needs were different.

While identifying a potential niche can indicate an opportunity, it does not always mean that a company’s products will actually fit Japan, or that early volumes and results will be in line with expectations. Also, a business’s commercial model is not always fully replicable in the Japanese market.

A stronger starting point for brands looking to add Japan to their list of overseas markets is therefore to treat intuitions and existing knowledge as hypotheses rather than conclusions. Properly evaluating the local competitive environment, pricing, and customer expectations is key to develop realistic positioning and market entry plans.

2. Not Researching the Target Audience

International brands with established customer profiles sometimes carry those insights into Japan with relatively little adjustment. However, Japanese customers might often have quite a different set of expectations and pain points to solve.

We have seen this with a supplement company that entered Japan with listings and packaging fully translated into Japanese, but without enough research into the customer it was actually trying to reach. While the resources had been professionally translated, the brand discovered that they had been built around a selling proposition that didn’t seem to match the priorities of the Japanese likely customer.

One SKU made the gap particularly clear. In the company’s home market, the product was positioned as a support to brain and heart health for people of all genders and ages. In Japan, however, COVUE’s market research revealed that competing products in the same category were more commonly framed around anti-aging and women’s beauty, suggesting that the likely Japanese buyer persona was more explicitly female and more beauty-focused than the company’s broader wellness positioning assumed.

In the end, the company moved to a different localization approach, which included developing more Japan-specific benefit messaging and updated labels, listing copy, and imagery across a broader part of their portfolio.

This example shows how misunderstanding the target audience can lead brands to invest heavily in localized content that still emphasizes the wrong benefits or fails to address the questions that matter to Japanese customers. The same foundational issue can impact wider marketing decisions, from creative direction to channel selection.

To avoid this potential pitfall, brands should therefore determine which aspects of their product proposition should be highlighted or adapted by understanding what their likely Japanese customer buys today, what influences their purchase decision, and how competing products are presented and why.

3. Entering Without Realistically Defining What Success Looks Like

A Japan entry needs a realistic definition of success. Without one, businesses can end up treating “being on the shelf” as the goal or judging performance mainly against previous market experiences, without a clear plan for what to do if demand develops more slowly than expected.

An example of this is the case of a health & wellness brand that entered Japan with an ambitious sales target but without a market-specific customer acquisition plan. The sales target had been in part built using sales data for their wider product category and relied on assumptions carried over from the brand’s home market. The target audience was similarly broad, initially described as Japanese consumers interested in premium supplements.

However, the company’s product came in a less common format than most other products in the same category already available in Japan. For the few existing products sold in a similar format, the available demand appeared to be considerably lower than the expectation. This suggested that customers would first need to be educated on the benefits of the format, with demand built progressively over time. A definition of success centered primarily on selling a large number of units was therefore not well suited to the current market situation.

This mismatch affected eCommerce performance. As the company had entered the market without enough research to clearly define the product’s positioning and customer acquisition approach, the Amazon listing struggled to rank for relevant searches. Several months after launch, the product was still difficult to find across many important search terms, which in turn limited awareness and sales momentum. Faced with the actual sales results, the company recognized that a more progressive approach to the market would be needed and decided to go back to the drawing board, starting with the development of a clearer customer acquisition plan.

This highlights how brands that approach Japan without clear and realistic targets for both customer acquisition and sales outcomes can end up conducting foundational research after launch, when those decisions should ideally have shaped the commercial plan from the beginning.

Setting solid, realistic targets and milestones can instead make the sequence of decisions clearer and more straightforward. They can help a brand determine when a launch should be considered successful enough to justify expansion, or whether the improvements required to reach its targets are worth the additional cost.

4. Choosing Channels Based on Familiarity Rather Than Local Fit

International eCommerce brands might have strong ideas about which channels they should use to enter a market.

One niche consumer goods company entered Japan with an eCommerce model that had already worked well in other countries. The company launched its own Japanese online store and planned to generate demand through familiar advertising channels, while also relying on word of mouth for discovery. The assumption was that once the localized store, content, and digital advertising were in place, sales would begin to build in a similar way to other markets.

However, COVUE’s research suggested that the platform chosen for launch might not be the best match for the brand’s target audience or its goals in Japan, while other channels appeared to be more closely aligned. In particular, Japan-based eCommerce marketplaces were some of the options most worth considering, as the platforms could give the brand more opportunities to appear where its target customers were already searching for and comparing similar niche products.

The brand continued with its initial launch model while monitoring performance and learning from the market. As sales developed more slowly than expected, the company began reassessing which channels could play a stronger role in improving discovery and conversion in Japan.

The experience shows why choosing a sales channel simply because it is familiar can lead to radically different results in Japan. The way Japanese consumers use online platforms, or where they expect to encounter certain brands, can differ considerably from what happens in other markets.

A stronger approach for eCommerce brands looking to grow in Japan is to define the positioning for the market by understanding how the target customer actually discovers and buys similar products locally, how online and offline channels work in Japan, and what role they should play in the wider market-entry strategy.

5. Underestimating the Budget Required to Build Traction

International eCommerce sellers about to enter the market often want their initial sales to cover their initial investment fully, if not generate a profit. However, not being prepared to support the initial costs of developing the market can cause brands to cut their budget before meaningful sales momentum has had time to develop.

A premium food brand entered Japan with the resources to launch on a major eCommerce platform and invest in digital advertising. A few months after launch, sales were steadily growing, and organic sales on the platform were gradually becoming a larger share of the total compared with promotional sales. However, the initial growth supported by this investment soon began to plateau, weakening the brand’s confidence in continuing to invest in the market.

While the company acknowledged that further promotion was probably needed to continue building momentum for a relatively new brand in Japan, it ultimately decided that it did not want to keep funding the brand’s development, ultimately resulting in the brand not developing further.

This experience shows how brands can underestimate the amount of time and resources required to develop a market presence in Japan.

Setting realistic expectations for the investment needed to support a brand’s development can instead help companies pace their budget in a sustainable way. Simply making a product available in Japan is rarely enough to build demand on its own, and some level of marketing investment is usually needed to generate awareness and create the traction required for future growth. Planning for that investment from the beginning can reduce the risk of underfunding the strategy or stopping too early when the product is beginning to show signs of having a genuine opportunity in Japan.

Better Preparation Reduces the Risk of Costly Mistakes

eCommerce allows brands to test, learn, and adjust as real market information becomes available.

But useful testing depends on having the fundamentals in place first. To reduce the risk of making avoidable mistakes during their Japan market entry, brands should be able to answer these five basic questions:

1. What evidence supports the opportunity we see in Japan?
2. Who is the customer we are trying to reach?
3. What realistic targets should define success in Japan?
4. Which channels should come first, and what purpose will each one serve?
5. What level of investment is realistically required to build our desired sales traction?

If several of those answers remain unclear, additional market-specific preparation may be more valuable than moving immediately into execution. Delaying a rushed launch for focused research or a measured test can be far less costly than learning through trial and error.
