We Consistently Create Great Results

We’ve worked with e-commerce brands across luxury fashion, saas, health, baby products, and outdoor gear… so we know what it takes to win over Japanese shoppers.

#1 We dramatically increased sales and presence within Japan for Reima

Reima, a Finnish children’s outdoor clothing brand, partnered with Humble Bunny to expand its e-commerce presence in Japan. We increased sales via brand localization and marketplace optimization for Amazon and Rakuten. As seen in the 6-month snapshot below, over the course of the project, we achieved a 101.1% average increase in Rakuten sales month-on-month.

The strategy involved optimizing product listings on Amazon and Rakuten, enhancing SEO, and creating compelling A+ content. They utilized targeted ads, seasonal campaigns, and improved customer experience through detailed sizing charts and local customer support. This comprehensive approach led to significant sales increases, higher conversion rates, and better brand visibility in the Japanese market.


#2 We successfully launched a product and saw a consistent increase in performance for DR. FISCHER

Dr. Fischer, an Israeli skin and healthcare brand, was looking for an omnichannel digital advertising strategy and optimization for the Japanese market and together, we were able to successfully launch the product in the Japanese market and increased sales by an average of over 50% per quarter.

The approach included organic social media campaigns, targeted Google Ads, and extensive use of Amazon features like Vine, Deals, and Subscribe and Save. This resulted not only in an increase in sales, but also enhanced product visibility, and a higher conversion rate through premium A+ content. The strategy also leveraged seasonal events to maximize sales and establish a reliable income through subscription purchases.

Humble Bunny triple track marketing analysis system

2. The true track

The HB True Track is a KPI and metric-monitoring framework for diligently monitoring the performance of channels. By understanding the different layers, we can determine the “stages” and maturity of our strategy along with whether we are employing the right techniques or need to adapt further to the brand’s needs.

  • Success Metric: While not a key indicator or a directly affectable aspect of the channel commissioned of this project, a success metric is defined as the “big picture” determiner of a project’s success. Something Humble Bunny pledges to diligently consider and to actively make decisions from. In some scenarios, hitting this might require CRO or other similar scopes
  • Core KPIs: Directly impacted KPIs for the platform. Upon hit, indicate performance on the scope commissioned. These are the true KPIs and standard evaluation metrics for performance. Hitting the targets at this level indicates that the channel itself is successful.
  • Signals: These are KPIs for momentum. These indicate we’re on the right track and making meaningful progress towards the Core KPIs above.

3. advanced optimization

To ensure we manage the creation and improvement of numerous listings efficiently, we’ve set up an advanced system that helps us to:

  • track every step of the optimization process
  • organize documents and research materials carefully
  • monitor progress closely

By setting clear milestones, we ensure each phase of creating listings—from the initial idea to final launch—happens smoothly and on schedule. This methodical approach guarantees that all product listings across different categories not only look great but also perform well in the market, meeting our clients’ expectations with precision and efficiency.

Our E-Commerce Testing Process

Japanese ecommerce agency services in Tokyo testing A+ content example
At Humble Bunny, we believe in the power of thorough testing that allows us to discover exciting optimization potential for our clients, as well as insights and learnings that can be leveraged across different platforms well into the future.

An example of that is the testing we have performed on the Amazon platform for Sleeping Baby. We have tested the impact of 3 following factors on the conversion rate:

  • Product images
  • Product name and description (copy)
  • Enhanced brand content (A+ content)

In order to make the test as unbiased as possible, we have focused on 3 separate products and launched the optimizations in stages:

PeriodProduct 1Product 2Product 3
Month 1New product images applied.New product copy applied.Unchanged (control group).
Month 2New product copy applied.Unchanged (control group).New product copy applied.A+ content applied.

On top of that, we took into consideration the additional factors that could have biased the test: stock levels, the popularity of particular patterns, as well as ongoing promotions and ads.

The results allowed us to discover which optimizations perform best in the Japanese market and gave us a direction for future conversion optimizations, as well as valuable insights for the client for growing in the Japanese market.

Habit of Overdelivering

120% delivery promise


For all of our e-commerce clients we follow a simple approach: always overdeliver. We strive to proactively exceed our client’s expectations by going the extra mile. An excellent example of that are Sleeping Baby product listings on Amazon: instead of following the generic patterns and plain images, we committed to an extensive review of best practice research. It allowed us to understand the value of visual asset quality and image annotations for Japanese consumers.

Consecutively, we ended up revamping the entire approach to product imagery: starting from redefining the unique selling points of the products, capturing it during product photoshoot, editing the images, designing icons and custom graphic elements, and finally annotating the product photography with all the visual elements and unique selling points.

Not only did the new images improve the conversion rate on the Japanese Amazon market, but were also used by the client for other online sales channels.
