  • Build a Shop Easily and Speedy Opening

    Shopify is a cross-border e-commerce platform from Canada, used by over 1 million companies. The number of companies introducing this technology is rapidly increasing in Japan. The advantage of this system is that it does not require installation of a system or a server, and can be quickly built and launched at low cost and in a short period of time.

  • Rich functionality and flexible customization

    Magento commerce cloud is a world class e-commerce platform provided by Adobe. The strength is its ability to scale to any size business and our thousands of extensions. There is an open source version and an enterprise version to choose from, depending on the scale of your business.

    eBay is one of the world's largest global marketplaces, with over 183 million active users and sales in over 190 countries. It is also an EC mall where Japanese products sell well, and we recommend you to open an eBay store first if you are working on cross-border EC.

  • The world's largest comprehensive online store

    Amazon.com is the world's largest e-commerce site, and Amazon's unique Fulfillment Centers (FBA), located in 175 locations around the world, allow you to sell products globally. The recommended method is to create a product catalog and leave the selling to Amazon.

  • A rapidly growing marketplace in Southeast Asia

    Shopee is an e-commerce mall in Singapore.

Frequently Asked Questions

I'd like to try cross-border EC, but it's tough if I can't speak English (a foreign language), right?

In fact, nearly half of our clients are not good at foreign languages, or cannot speak them at all.However, in reality, machine translation is usually sufficient for communicating with buyers, and cloud translation is the mainstream for product descriptions, so don't worry. Our companionship support also helps you with language concerns.

What is the difference between the enterprise versions of Shopify and Magento?

Shopify has Shopify Plus, Magento has Adobe Commerce Cloud, and other enterprise versions. In the case of Shopify, this is necessary if you need in-cart customization, B2B functionality, or if you want to operate in multiple languages and multiple currencies with different rules and customers in different countries.

Magento is used when the number of product SKUs exceeds 10,000, or when you want to avoid bugs in the open source version or extension matching as much as possible, or when you want to manage licenses or have a large number of staff involved.

We want to start a thorough cross-border EC business in China; we are considering selling our products on JD.

This is a country with the world's strictest rules and the highest hurdles to opening a store, led by the Alibaba Group, which says, "If you have a product that sells 100 million yen a year, let's discuss it”. The cost of the project is also inordinate, requiring tens of millions of yen from the first year.You can't do it lightly and say, "Let's see if it sells on a trial basis.”

Therefore, in the first year, we recommend that you familiarize yourself with the No. 2 cross-border EC markets of Europe, the United States (English-speaking countries), eBay and Amazon, or your own EC site on Shopify or Magento.
