This will be most relevant if you are opening an online shop in Japan.
Some people want to open an online shop but aren't sure which service to use.
This article explains recommended online shop services for those opening their first online shop. We also cover how to choose a service that fits your business, and key points beginners should keep in mind when running a shop.
Types and Characteristics of Online Shops
Online shops fall into three types: marketplace-type, self-hosted, and ASP-type. Here, we explain the characteristics of each.
Marketplace-Type Online Shop
A marketplace-type online shop is where multiple shops open stores on a single site. Amazon and Rakuten Ichiba are examples. Since these platforms are well known and have strong customer-drawing power, a major appeal is that your shop can catch customers' eyes even without putting much effort into customer acquisition.
However, costs for opening and running a shop — such as listing fees and sales commissions — tend to be higher than with other types. Since the design format is fixed, it's also harder to express originality.
Self-Hosted Online Shop
This means launching a shop on a server you've prepared yourself. There are no costs at all, such as sales fees or listing fees.
You need to source all the features required to run an online shop yourself, but in exchange you can freely customize the design and text. However, be aware that it's hard to gain customers without actively working on customer acquisition.
ASP-Type Online Shop
ASP-type means launching a site using a service equipped with all the features needed to open and run an online shop. BASE and Shopify are examples.
You can easily build the ideal online shop even without any site-building knowledge. Costs for opening and running a shop are kept lower than other types, making it appealing as a low-risk way to start.
However, as with self-hosted shops, it tends to be hard to gain customers without customer acquisition efforts.

How to Choose an Online Shop Service That Fits Your Business
Here, we explain how to choose an online shop service that fits your business.
How Much Is the Setup Fee?
When choosing an online shop, check the setup fee.
If you spend a large amount before you have any sales, you risk not being able to recoup it. Running an online shop also involves monthly usage fees, payment processing fees, and optional feature costs.
Before launching, carefully calculate not just the setup cost but also the ongoing costs of running the shop, and choose a service that lets you achieve your expected profit.
Is Strong Support Available?
If your company doesn't have staff with online shop expertise, opening and running your first online shop isn't easy.
Support varies by service and plan. When launching your first online shop, it's a good idea to choose a service with as much support as possible.
Does It Have the Features to Achieve Your Goals?
Online shop services differ in their characteristics and range of features. If you choose based on cost alone without checking whether the features match your goals, you may not be able to achieve the online shop you envisioned.
Check whether the service has the features needed to achieve what you want from your online shop — such as "I want to expand overseas" or "I want to focus on design."
Does It Support a Wide Range of Payment Methods?
The payment methods an online shop supports vary by shop.
If the available payment methods are limited, customers are more likely to leave without completing a purchase. Choose a service that supports as wide a range of payment methods as possible.
Minimum Points Beginners Running an Online Shop Should Know
To avoid failure, beginners running an online shop should keep the following points in mind:
- Put effort into customer acquisition
- Comply with the Act on Specified Commercial Transactions
- Take security measures
We'll explain each of these in detail below.
Put Effort into Customer Acquisition
Whether you can turn a profit running an online shop largely depends on your ability to attract customers.
If you start an online shop outside of a marketplace-type platform, the likelihood of catching customers' eyes without customer acquisition efforts is extremely low. Use social media and advertising to keep reaching your target audience.
Comply with the Act on Specified Commercial Transactions
Note: The following legal requirement is specific to Japan. The Act on Specified Commercial Transactions is a law that applies to types of transactions prone to consumer disputes, established to protect consumers' interests. Online shops fall under the mail-order sales category defined by this Act.
Set up a page on your site titled something like "Notation Based on the Act on Specified Commercial Transactions," and be sure to include the required items, such as the seller's name, address, and phone number, the timing of product delivery, and the selling price.
For details on the Act on Specified Commercial Transactions, see the Act on Specified Commercial Transactions Guide.
We also cover the required notation under the Act on Specified Commercial Transactions in the blog article below. Please use it as a reference.
Take Security Measures
Online shops handle customers' personal information. Because of this, it's important to take security measures as strong as possible to prevent personal information from leaking.
It's important to invest in a solid setup, such as using paid rather than free antivirus software on your computer, even if it costs more.
If You're Opening an Online Shop, Shopify Is Recommended for Its Low Cost and Strong Support
Online shop services come in two types, marketplace-type and ASP-type, and we recommend ASP-type, which lets you open and run a shop at low risk.
Among ASP-type online shops, Shopify has a 0 yen setup fee, and its monthly fees and sales commissions are also set at relatively low rates. Because of this, Shopify is especially recommended for anyone who wants to start an online shop easily and at low risk.
Use the online shop service that fits your business to achieve the online shop operation you envision.
