The exhibition area will be doubled in size upon completion, making it possible to permanently exhibit many items (including all fifty faces of "Rokuonji Oshoin Shohekiga" (Wall painting in Osho-in Room of Rokuon-ji Temple) by Jakuchu ITO) that are currently not exhibited due to lack of space.
完成後は展示室面積は倍以上になり、現在スペースの都合で展示されない作品多数（伊藤若冲の「鹿苑寺大書院障壁画」全50面を含む）が常設展示されることになる。
