Regelski Collection is a private collection located in Helsinki, Finland, of presently over 3500 works of Japanese antiques and art. It was started in 1983 when its founder, Professor Thomas A. Regelski was in Japan teaching in the Aichi University. It then continued to grow slowly in the U.S.  by purchases at various antique shops and occasional travels to Japan. Since 2000, while Thomas was residing in Finland, most of the collection was acquired online. As the collection grew, together with his wife Kaisa, he decided to present the collection to a wider Finnish audience and share it in an educational format for those having little experience with Japanese art, especially Finns.

The text, originally planned to be published as a book, provides a general introduction to Japanese traditional arts and the Japanese spirit. Also, background information is given about various items chosen (less than 15 % of the total) for the website. In time items in excess, duplicates, and vintage from the collection will be sold —but will maintain the basic collection.
