1. What are Amazon reviews?
Amazon reviews are a method for customers to share their experiences with stars (★1 to 5) in text format for products sold on Amazon.co.jp. By making third party voices visible, reviews answer questions that customers who see the product for the first time have, such as “is this the product I’m looking for?”, and helps encourage their purchase decisions.
Point
- Each review reflects an individual opinion, but as the number of reviews increases, a wider rage of perspectives and experiences are shared, so customers gain a deeper understanding of the product.
- It’s important that the text content of the review is specific, including usage scenarios, size, compatibility, strengths and weaknesses, etc.
2. Types of reviews: Product reviews and seller reviews
There are two main types of reviews. Since their purposes differ, the trick is to plan your approach to each separately.
Type
Overview
How to respond
Product reviews
These are the reviews shown under the title of the product page. They contain evaluations of the product itself, such as how it feels to use, the quality, and its functionality.
If you want to improve your product reviews, it’s important to provide more detailed information on the product page and reduce the gap between customer expectations and the actual product. Additionally, maintaining strict quality control and clearly explaining how to use the product and any precautions can help improve customer satisfaction.
Seller reviews
These are the reviews shown on the seller’s page. They evaluate the overall purchasing experience, including packaging quality, delivery speed, and responsiveness to inquiries.
For seller reviews, you can improve the overall level of satisfaction with the purchasing experience by ensuring fast and careful shipping and by responding to customer inquiries quickly and carefully.
Both kinds of reviews are important for ensuring customer satisfaction, and continuous improvement can lead to even better service.
3. The importance of star ratings and the balance between “quantity x quality”
The role of star ratings
For reviews on Amazon, the star rating and number of reviews are one of the important factors in customers’ product decisions, and serve as a place for both customers and sellers to exchange valuable information. Receiving honest opinions from customers can lead to the provision of better products and services.
The value of review text content
The review text content explains the reasons behind a rating, such as “why was it evaluated that way?”, which can’t be conveyed by just the number of stars.
Reviews that describe how the product feels, usage scenarios, reasons for purchase, etc. are extremely helpful for other customers to imagine how they might use the product themselves.
Also, for sellers, reviews provide valuable “qualitative data” that clearly identify a product’s strengths and areas for improvement.

Benefits for customers
- When choosing a product
Comparing both the star ratings and text content when selecting products makes it easy to compare within the same price range and category. - When making a purchase decision
Knowing about real user experiences in advance, allows customers to make purchases with confidence. - Sense of participation in improvements
By posting reviews and experiencing how their opinions can lead to product improvements, customers are more likely to develop and stronger connection to the brand.
When it comes to star ratings, it’s not just “the more the better” or “the higher the better.”
What matters is the balance between quantity (number of reviews) and quality (specificity/reliability). Products that gather opinions from many people and consistently receive high ratings for certain aspects are more likely to attract the interest of more customers. ] The “accumulation of trust”
built through reviews is the foundation that supports the long-term growth of the brand.
Next, let's take a look at the specific business benefits that actually come from increasing reviews.

4. Benefits of getting more reviews (business impact)
As the number of reviews increases, you have more opportunities to catch the eye of customers in search results and product pages, making it more likely for customers to refer to your product when considering a purchase. Specific suggestions mentioned in the text content of the review provide insights for improvement. As a result, this can lead to mid- to long-term results, such as lower return rates, improved advertising efficiency, and higher repurchase rates.
Key benefits of increasing reviews
- Contribution to brand evaluations
Gathering many high-quality reviews makes customer evaluations and experiences with your product visible, and it is one of the deciding factors for new customers when considering a purchase. - Insights for improving products and service
Comments such as “sizing information is hard to understand” or “packaging is excessive” reveal specific areas for improvement. - Lower return rates
Narrowing the gap between customer expectations and the actual products can help decrease cases where people feel “this is not what I expected.” - Improved advertising efficiency
Products with many reviews tend to have higher conversion rates from ads, leading to a greater return on advertising costs.
In this way, increasing reviews is not simply “increasing numbers”; it’s an important step for building relationships of trust with customers and providing better products and services.
