NAOSHIMA, Kagawa Prefecture--Admission fees will be raised at 11 modern art facilities run as part of the Benesse Art Site Naoshima project on three islands in the Seto Inland Sea from Oct. 1, operators said.

The plan was announced by the Fukutake Foundation, a public interest body headquartered here, and Benesse Holdings Inc., an Okayama-based company involved in education and publishing.

The collaborative art project features 20 facilities on Naoshima and Teshima islands in Kagawa Prefecture and Inujima island in Okayama Prefecture.

Admission fees will increase by a maximum of 900 yen ($6.30) at 11 sites, including the Chichu Art Museum and the Art House Project on Naoshima and the Teshima Art Museum on Teshima.

An online ticket sales system will also be introduced at all the facilities, except for the Naoshima Bath “I Love Yu,” to help deal with increased visitor numbers from in and outside Japan.

The aim is to improve usability and ease congestion.

Online tickets will be up to 300 yen cheaper than paying at the door for most of the facilities. Tickets for several facilities for entry in and after October can be purchased from the same page.

Different rates reflecting changes in market conditions will be introduced at the Chichu Art Museum on weekdays, weekends and holidays.
