If you operate an ecommerce site in Japan, you might have come across the term “churn rate.” Churn rate is a useful indicator for tracking subscription cancellations; it represents the percentage at which subscriptions are cancelled.

While subscription-based business models tend to generate stable revenue by encouraging customers to make ongoing, repeat purchases, an increase in cancellations could undermine stability. Therefore, when operating a recurring service on a Japanese ecommerce site, it is necessary to have strategies for both acquiring new customers and retaining existing customers.

This article will explain the key concepts, main causes, and countermeasures you need to know to prevent subscription cancellations on Japanese ecommerce sites.

Key takeaways

• There are two types of subscription cancellation: “voluntary churn,” which is caused by the customer’s own actions, and “involuntary churn,” which results from factors such as payment failures. It is best to tailor countermeasures to the specific cause.
  
• The subscription market in Japan is expanding, and since users can choose from multiple services, small issues can quickly lead users to cancel a subscription. For this reason, it is necessary to implement measures not just to acquire new customers but also to encourage existing customers to continue using your service or product.
  
• To prevent voluntary churn, it is helpful to offer the option to adjust delivery frequency or plan options, follow up after the first purchase, and offer recommendations tailored to the reasons for cancellation.
  
• To prevent involuntary churn, it is important to establish a system to notify customers of unsuccessful charges and a process to update their payment methods. Payment tools that support recurring billing are useful.
  

What is churn?

Subscription cancellation (churn) refers to a customer’s termination of a subscription or recurring purchase. In subscription-based businesses, such as recurring purchases and membership services on an ecommerce site, the churn rate measures the percentage of customers who cancel plans within a given period.

Calculating churn rate

Churn rate is the percentage of customers who cancelled their subscriptions within a specific timeframe. The general customer churn rate is calculated as follows: the number of customers who cancelled the plan during a given period is divided by the number of customers at the start of that window.

Customer Churn Rate = Number of Customers Who Cancelled During a Given Period ÷ Number of Customers at the Start of That Period x 100

For example, if you have 1,000 subscribers at the beginning of the month and 50 cancel during that month, the customer churn rate is 5%.

For subscription businesses, the impact of cancellations can be assessed not just by the number of customers but also by how they affect monthly recurring revenue. The churn rate tied to monthly recurring revenue (MRR) is calculated by dividing the MRR lost due to cancellations during a given period by the MRR at the start of that period.

MRR Churn Rate = MRR Lost Due to Cancellations ÷ MRR at the Start of the Period x 100

For example, if the MRR at the beginning of the month is ¥1,000,000 and ¥50,000 in MRR is lost from cancellations during that month, the MRR churn rate is 5%.

The difference between voluntary churn and involuntary churn

Churn is generally split into voluntary and involuntary.

Voluntary churn refers to customers who choose to cancel their subscriptions. In contrast, involuntary churn occurs when a contract cannot be continued because of changes in card information or billing errors, although the customer has no intention of cancelling the service.

The causes and countermeasures differ by type, so when implementing retention measures, it is necessary to identify which type of cancellation happens most frequently.

Japan’s subscription market and the importance of churn prevention

In Japan, there remains strong interest in online retail models built around ongoing use, including subscription services and membership programmes. According to the market research firm IMARC Group, the country’s subscription-based ecommerce market reached $23.3 billion USD in 2025 and is projected to grow to approximately $461 billion USD by 2034.

As the subscription market has expanded, more companies have entered the space, giving users more options to compare and choose from. Rather than staying with one service long-term, many users now switch between subscriptions that suit current needs at any given time, including free trials, discount promotions, and seasonal events.

As a result, when offering a subscription service on a Japanese ecommerce site, it is important to focus not just on acquiring new customers but also on retaining existing ones. It is also helpful to monitor churn rates, identify the reasons for cancellations, and continuously improve products, pricing plans, subscription payment methods, and customer service.

Main causes of subscription cancellations

The causes of subscription cancellations differ between voluntary churn, where a customer cancels of their own accord, and involuntary churn, which happens due to payment failure or other factors.

Main causes of voluntary churn

Voluntary churn is more likely when customers are dissatisfied with a product or offering or no longer feel the need to continue using it.

The main reasons for this are:

• Unhappy with the product or service
  
• Frequency of use has decreased
  
• Price felt expensive
  
• Changed to a competitor’s plan
  
• Plan details and delivery frequency weren’t a good match
  
• Problems with customer support
  

For subscription services on ecommerce sites, a gap between customers’ expectations at the time of the first purchase and the products or services they actually receive could easily lead to early cancellations. For food or cosmetics subscriptions, if the customer has leftover, unused products because the delivery frequency doesn’t match usage patterns, it might result in cancellation.

Main causes of involuntary churn

Involuntary churn occurs when a cancellation happens without the customer’s knowledge, often because of a declined charge, although they had no intention of cancelling.

Main cases include:

• The credit card has expired
  
• Card information has changed
  
• Incomplete payment because of insufficient funds or available balance
  
• The registered payment method can no longer be used
  
• Payment could not be completed due to a system error
  
• Notifications following payment failures and the retry process were insufficient
  

Because involuntary churn isn’t caused by dissatisfaction with a product or service, making subscription payment methods, notifications, and renewal procedures easier to understand will help reduce or avoid cancellations. In particular, since subscription-based ecommerce relies on recurring payments, it is useful to have measures in place to deal with unsuccessful charges.

Measures to prevent subscription cancellations

The following sections explain strategies and measures to prevent subscription cancellations, broken down by whether they target voluntary or involuntary churn:

Measures to prevent voluntary churn

To prevent voluntary churn, customers need a clear reason to keep using the offering. That might involve reviewing product and service quality, pricing plans, and available support. The goal is to create an environment where customers can easily continue using the subscription.

Allow flexible changes to delivery frequency and plan

Consider that lifestyle shifts could keep customers from using your subscription service at the same pace as before. For instance, when life events such as childbirth, moving, or a long-term business trip happen, options including a temporary pause, changing the delivery frequency, or skipping a delivery allow the customer to adjust how often they use the service without cancelling the subscription entirely.

Follow up after the first purchase

Customers who acquired subscriptions through introductory discounts or promotions might consider cancelling their subscriptions when the price returns to normal levels. By following up after their first purchase and providing the customer with details on how to use the product, the benefits of continued use, and the timing of the next delivery, rather than focusing solely on price, you can convey the value of the product or offering itself.

Present options tailored to the reason for cancellation

Ensure that when customers are about to cancel, there is a way to ask why. By understanding any issues with the products or plans, you can improve them going forward. If the customer’s reasons for cancellation are focused on price, usage, or delivery frequency, it might be possible to reduce the cancellation by proposing a different plan, a pause instead of cancellation, or a limited-time offer.

Measures to prevent involuntary churn

To prevent involuntary churn, ensure customers can easily and quickly update their payment method when a charge fails. When a customer has no intention of cancelling a subscription, cancellation could occur due to factors such as a card expiration, an insufficient balance, or changes to card information.

Notify the customer when payment fails

When a payment fails, it is best to notify the customer quickly. Notifying customers by email or through their account that a charge has failed and explaining that they need to revise their payment method or retry will help them understand what steps to take next.

Make it straightforward to update the payment method

If a transaction cannot be processed due to changes in card information or an expired card, customers must be able to update their payment method immediately. Making the process of changing checkout options straightforward within the account will help avoid cancellations from payment failures.

Use payment tools that support recurring billing

While it is possible to implement and manage payment methods individually, using a payment service or subscription tool that supports recurring billing lets you centrally manage tasks such as rebilling, revising ways to pay, and notifying customers, improving overall convenience.

The features vary from tool to tool, but some could include recovery options for failed charges, including automatic retries, customer notifications, and guidance on updating payment methods. Proper use of these features can help reduce churn.
