Privacy Policy

This is our attempt to make a simple and easy-to-understand privacy policy. You may contact us if you have questions.

What personal information we collect and why we collect it

In general, we try our best to collect only the personal information that we need to complete your order or answer your questions correctly. We are not interested in using your information for other purposes.

Basic Information

Our website collects information that we need to process your order, including your name, email address and location. You enter this information voluntarily, but without it we might not be able to help you.


Our website does not use cookies except for analytics described below.


Our website uses analytics which records information about your visit, such as how you arrive at our site, which pages you visit and links you click, and your country. We also use a mailing list service that can tell us if, when, and how many times you open certain emails that we send.

Credit Card Information

We do not see or collect your credit card information. We process all payments with third-party services that are much bigger than us and much more capable of protecting your card information.

Who we share your information with

We will never sell or give your personal information to marketers. However, there are various third-party services that we use to do our job and to keep records, and they may see some or all of the information you provide to us, or send us some information that they collect. These services include our email provider, server provider, cloud spreadsheet, cloud database, cloud sync and back-up, mailing list and transactional email service, website live chat, payment processors, and shipping companies. If you are on one of our stable tour visits, we share your name and age with our insurance company so that we can insure you for that event. We are based in Japan, but the third-party services we use can be located all over the world. We won't publish the list of third-party services that we use here, but we can provide it to you if you request.

It's unfortunate that we have to write this next part, but we do. Harassment, threats and extortion are not covered by our privacy policy. If you send us messages containing any of these things, or other criminal activity, we reserve the right to turn over your messages and personal information to the authorities or even into the public domain.

How long we retain your information

We generally delete emails and other personal information after about 7 years. We do not use your information to market to you after your order is complete. You should only receive emails about the order you've made or other inquiries you have sent to us. We keep your information for our records only.

What rights you have over your information

You can request to receive a summary of the personal information that we have about you. You can also request that we erase your personal information. This does not include any information we must keep for administrative, legal, tax, or security purposes. We will not erase any information that is for an order less than 180 days old. This is because of the policies of credit card companies and payment processors. Some information, for example your emails, we will not erase unless they are more than 7 years old. This information is needed in case of a tax audit from the Japanese tax office, so that we can prove the details of your order.
