What is NET CASH?

What is NET CASH?

NET CASH is a prepaid electronic money service provided by NTT Card Solutions, a subsidiary of Nippon Telegraph and Telephone Corporation (NTT), a leading telecommunications company in Japan and the world’s fourth-largest telecommunications company. Launched in 2002 (originally called CALETE), NET CASH enables online shopping using a unique 16-character ID.

These IDs can be purchased at convenience stores (konbini) throughout Japan via a terminal. The terminal issues a ticket with the ID, which users can use for online transactions. This method allows individuals without credit cards or those preferring anonymity to shop online without divulging personal information.

It’s particularly useful for minors under 18 who cannot legally own credit cards but still wish to make digital purchases. In that regard, NET CASH is popularly used for online and mobile in-game purchases, Japan-exclusive social media services like LINE, Nico Town, and WAKU+, digital comic books (manga), and online music and videos. One notable platform that uses NET CASH is Mora, an online music and video store for the Japanese market operated by Sony. NET CASH offers dedicated prepaid cards for Mora purchases.

NET CASH Features

NET CASH offers various features, including:

  • Alternative Payment Option: NET CASH offers an alternative for individuals without access to or those who prefer not to use credit cards. This includes minors under 18 who cannot legally own credit cards but still want to make digital purchases.
  • Discounts: NET CASH credits can be purchased at a discount.
  • Security: NET CASH transactions are secure, providing a safe alternative to credit cards.
  • Versatility: NET CASH can be used for various online services, including gaming, streaming, and e-books.
  • Points Program: Users can earn points using NET CASH for payments and affiliated services, which they can redeem for additional NET CASH.

Discounts, Security, and Points

The primary benefit of NET CASH for users lies in its value. Unlike other digital prepaid services in Japan, NET CASH offers incremental discounts based on the amount purchased. At convenience store terminals, users can buy NET CASH tickets with the following discounts:

  • ¥1,600 (no discount)
  • ¥2,000 for ¥1,990
  • ¥3,000 for ¥2,990
  • ¥5,000 for ¥4,980
  • ¥10,000 for ¥9,950
  • ¥30,000 for ¥29,700 (Lawson exclusive)
  • ¥50,000 for ¥49,500


These discounts are particularly beneficial for users who frequently use NET CASH or make large purchases. By taking advantage of these savings, users can get more value from their spending, making NET CASH an attractive option for digital transactions.

Moreover, as NET CASH is operated by NTT Card Solutions, it benefits from the extensive experience and security infrastructure of the NTT Group. Transactions only require the unique 16-character ID found on the purchased ticket, activated after purchase.

NET CASH also offers a rewards program for customers using the NET CASH Wallet. By charging NET CASH to the wallet and using it for payments, customers can earn points equivalent to 0.5% of the payment amount. Accumulated points can be exchanged for NET CASH. Points can only be earned through payments from the NET CASH Wallet and not by using a regular NET CASH ID. The expiration date for points is one year from the date they were last awarded or exchanged. The accumulated points will expire if no points are earned or exchanged within a year.

Similarly, Japanese point sites such as Warau and ChobiRich enable users to convert accumulated points into NET CASH Wallet credits. For instance, on Warau—a platform with 2.6 million registered users—points, known as “Warau Points,” can be earned through affiliated services, surveys, and games. These points can then be exchanged for NET CASH credits, offering users an alternative way to obtain NET CASH without direct purchase.

How NET CASH Works

There are two types of NET CASH:

  • NET CASH Web Type: Users acquire their NET CASH ID online.
  • NET CASH Sheet Type: Tickets can be purchased at convenience store terminals.


Physical NET CASH ID prepaid cards are available at select retailers, such as Galileo, a retail gift card shop in Japan. However, NET CASH IDs are typically acquired from terminals in convenience stores. These terminals print out a ticket with a unique NET CASH ID, which is then paid for and activated at the convenience store register.

NET CASH IDs can be purchased at:

  • Seven-Eleven
  • Lawson
  • Family Mart
  • Ministop

How to Make a Payment with NET CASH

To make a payment online with NET CASH:

  1. Select Payment Method: At checkout, select “NET CASH” as the payment method.
  2. Enter NET CASH ID: Enter the 16-character NET CASH ID.
  3. Follow Instructions: Follow the on-screen instructions to proceed with the payment.


Users cannot add funds to an existing NET CASH ID. If the balance on a NET CASH ID is insufficient for payment, they must enter a new NET CASH ID with sufficient funds.

If, at checkout, the balance of a NET CASH ID is insufficient, users should be prompted to enter an additional NET CASH ID. By entering a different (new) NET CASH ID with a balance, they can use up the old NET CASH ID and complete the payment.

Users can check their balance by visiting the NET CASH homepage.

What Is The NET CASH Wallet?

NET CASH also provides the NET CASH Wallet, a free digital wallet service that adds to the convenience of using NET CASH. Users can easily manage, store, and utilize their NET CASH funds by registering as wallet members with only an email address.

Since tickets with NET CASH IDs can be lost, utilizing the NET CASH Wallet is advised. Once an ID is registered with the wallet service, there is no need to worry about losing it. Additionally, the wallet service allows users to manage multiple NET CASH IDs simultaneously.

Once users register their NET CASH ID in the wallet, they can make payments at affiliated stores by selecting “wallet payment” and using their wallet account and password. This eliminates the need to enter the NET CASH ID for each transaction.

Users can review their transaction history, detailing when and where they purchased at affiliated stores and the amounts spent. This feature also lets users track which ID was used for each transaction. Additionally, users can manage NET CASH earned through exclusive store campaigns.

NET CASH Wallet Features

NET CASH Wallet features include:

  • Easy Payment: Register your NET CASH ID in the wallet to make payments using your wallet account and password, avoiding the need to re-enter the NET CASH ID each time.
  • Earn Points: Earn points with each payment by registering your current or newly purchased NET CASH in the wallet. These points can be exchanged for NET CASH.
  • Track Usage: Monitor spending details, including dates, locations, and amounts. View the ID used and manage any NET CASH acquired through affiliated store campaigns.
  • Additional Security: Users can lock and unlock their NET CASH Wallet to prevent unauthorized purchases.
  • Simple Registration: Sign up with just an email address. Whether you’re a new or existing NET CASH user, setting up the NET CASH Wallet is quick and straightforward.

How to Make a Payment with The NET CASH Wallet

  1. Select [NET CASH] as the payment method.
  2. Below the normal NET CASH ID prompt, enter the NET CASH Wallet account name and password, then click the [Login] button.
  3. Review the payment details, and if everything is correct, click the [Confirm] button.
  4. Follow the on-screen instructions to complete the payment process.
