Payment Methods Information offers two payment methods. Online payment by credit card and offline payment by "Postal Money Order". Payment by credit card is possible from almost all countries, however, payment by Postal Money Order is limited to certain countries and is subject to conditions (see detailed section below).

Credit card payments on SeidoShop are made via Stripe or go through Paypal, Paypal account is not required and the payment is processed as on any other credit card payment platform. Paypal offers the highest level of security available today, both technically and practically.

Although the shop's currency can be set depending on your location, all our prices are determined in Japanese YEN and your shopping cart will automatically switch to YEN at checkout. Conversions between your currency and JPY are fully transparent when making payments by credit card or via Paypal account. For the payment, you have nothing to do but to enter your billing address and credit card information.

Credit card payment via Stripe (main payment method)

  • The fastest way to pay on SeidoShop: Nothing more is needed than entering your credit card information at checkout.
  • Accepted cards: Visa, MasterCards and American Express (some cards may not be accepted from certain countries) .
    Stripe does not accept disposable/one-time-use/Ecards.
  • Payment currency: Japanese YEN (conversion is automatically made by your bank).
  • Debit on your account: immediate (can take a few days depending on your account details)
  • Fraud protection: yes, with the highest standards of the industry.
  • Security level: PCI level 1, currently no higher level of security available.

Stripe is a well known gateway with a very good reputation in both, Europe and North America. Its Japanese version was made available to us in June 2016 and we decided to implement it immediately as it offers a far smoother checkout experience to our customers than PayPal. We hope you'll like it !

Payment refusal ? It is for your own safety

Prepaid credit card refused

Paypal will check the following elements when processing a payment and come up with a "potential risk of fraud" ratio. If this number is too high, your payment will be blocked. Here are a few key points that might prevent you from validating your payment and some solutions.

  • Verification: The transaction history of the card holder which includes data shared with other financial institutions.
    Solution: If you have a complicated history with your bank, you can try a card from another bank, or borrow a card from a friend. That is the only solution.
  • Verification: Flow deviation, which means that Paypal monitors your browser activity during the payment process. Opening another website in a new tab during the payment process may be interpreted as a risk by the Paypal fraud prevention algorithm.
    Solution: Finish the payment process at once and without consulting another website.
  • Verification: Paypal verifies where you physically are, where the store is you are buying from as well as the delivery address.
    Solution: make sure your billing address is the same as used for your credit card registration. Try to use a shipping address in the same country as the billing address (if you absolutely need to be delivered in another country, we can modify your shipping address afterwards).
  • Verification: Paypal verifies the potential risk of your internet connection (softwares used to retain/hide data or make your connection anonymous are suspicious).
    Solution: deactivate all softwares that may prevent your localization, especially browser extensions/apps (you can keep your firewall on). If you are using a public network (open Wi-Fi, work, school), please try again from home (it will be far more secure for you anyway).
  • Verification: Paypal needs to verify the identity of the card's bearer.
    Solution: contrary to what is announced by many banks, this is not possible with some E-Cards/disposable cards. Payments by E-Card will thus automatically be rejected so the only solution is to use another card.

You still can not process the payment ? First, please check with your bank if you have all the authorizations needed to place a payment online in a foreign country.
If so, please contact us. We will send you a Paypal money request for your order. This will override the verifications related to your localization. If this does not work either, you will have to try with another card.

If you already registered your card number or your email address on Paypal (account creation), you must login to process the payment.
For obvious security reasons, any card registered on Paypal cannot be used without login into the Paypal account.

What about credit card payment security ?

PayPal’s website is as secure and encrypted as our own checkout when paying with Stripe meaning both methods have the same level of security. If you are on a secured connection on your end, the information you exchange is hidden from third parties. Stripe and Paypal use many kinds of security features that you would expect from any world scale financial institution and as far as we know, none of they ever experienced any credit card information leak.
However, it happens to have your data stolen from a risky behavior on your end, so here are a few tips to avoid any trouble with your card, at least on our website.

Payment Security
  • Never place any order from a public connection (i.e. public Wi-Fi, internet cafe, etc.)
  • Never click on any Paypal link you may find in emails (except from the receipt you receive right after your payment), or if you do so, do not enter any password/sensitive information on the landing website. Almost all hackers try to make you type your personal information on their own "fake/imitation" website. It is called "fishing".
  • Last but not least: Never leave your credit card unwatched. The very large majority of credit card frauds happen due to information stolen on the card itself (i.e. taking a picture of the card behind the counter...)

Postal Money Order

Payment is to be made at your local post office. Please note that this service is only available in the following countries : USA, Mexico, Peru, France, Austria, Germany, Greece, Italy, Portugal, Poland, Spain, Switzerland, China, Hong Kong and Korea. Any order placed with a billing address registered in a country not listed above will be immediately canceled.

Postal Money Order
  • Usually takes 7 to 10 days to reach us.
  • The postal order is issued at your usual post office (the availability of the method and its cost - very limited - depend on the countries and regions).
  • The amount must be notified in Japanese YEN, the agent will perform the conversion and the settlement is made in your currency.
  • Payment is sent to our mailing address: Seido Co., Ltd. 351-0101 Saitama-Ken, Wako-shi, Shirako 2-27-51, Japan
  • Once we received the payment, we will send you a notification by Email, indicating the initiation of your order processing. Please note that your order will only be processed after reception of the payment and payment delays will therefore incur equivalent shipping delays.

This method of payment is not "cash on delivery", the payment must reach us BEFORE we ship your order.

Pricing in Japanese YEN and other currencies

Currency Exchange logos

Our prices are set in Japanese YEN to insure a better price.
Indeed, Seido is based in Japan, and therefore, we receive final payments in YEN. Billing your orders in EUR would require us to take a "safety margin" to cover changes in exchange rates, hence making you pay more. By charging directly in YEN, you ALWAYS pay the best available change rate at the time of payment, and we do not need to apply an additional margin.

All the amounts shown on our website in a currency other than the Japanese Yen (JPY) are there for your comfort of navigation and are subject to fluctuations of the exchange rate, therefore the amounts may differ from the amount actually paid (the difference in the exchange rate, and exchange fees charged by your bank). The final payment on our website will always be displayed in JPY, regardless of the currency selected for display.

Conversions between your currency and JPY are automatic and fully transparent when making payments by credit card or Paypal account. You can view prices in JPY, EUR, or in USD, CAD, and GBP, at your convenience. All the prices displayed on the site, including descriptions, are transcribed in your currency. The exchange rate is updated twice a day from a dedicated website: We add a 5% conversion rate to the official rate so most of the time, the final amount charged on your credit card will be slightly lower than the one displayed on the website.

Other payment methods

Payments by bank transfer:

International bank transfers to Japan are a bit complicated: Our bank, alike all Japanese banks, will charge 4,200 YEN for receiving an international transfer, add currency exchange fees and use a terrible exchange rate for incoming payments set in another currency than Japanese Yen.
This method should therefore be requested in advance by email and the minimum order amount for bank transfers is 100,000 JPY.
As we also need to justify the reasons of the transfer to our bank (measures against international fraud), we will refuse all transfers that have not been pre-approved by email.

Other options: e.g. cash payment:

Payment in cash, sent by ordinary mail or hand delivered by an acquaintance living in Japan is also possible.
Local bank transfers (Japan > Japan) can not be accepted for international orders (shipped outside of Japan).


Payments by check, Western Union, or any other methods are not accepted.
