"Originally created for the Echigo-Tsumari Art Triennale in 2000, this structure has a concrete ground floor and wooden upper level whose roof opens to frame the sky, filling the tatami-lined interior with shifting natural light; at sunrise and sunset the interior lighting changes to emphasise the colours of the sky, it is one of the few Turrell works in Asia that can be booked for an overnight stay, and it is roughly a two-hour train journey from Tokyo." - James P.
