[About Keeping Koi in Japan]
Basically, we are not able to keep Koi in Japan a long term that are not indicated as "Including Keeping Charges ", "Possible to Keep in Japan for 50,000yen", "For Koi Show in Japan" etc. in the description of the Koi for the auction.

If you need long-term (more than 2 months) keeping in Japan due to circumstances beyond your control, please email or call us before bidding.

We shall not be liable for death, disease, injury or/and quality decline of the Nishikigoi during the period of the keeping in Japan.

We will refund the whole amount when Koi sold as female was found out to be male.
