To be clear Ise is in Mie Prefecture, hence the possibility of travelling together.
The "Geku" and "Naiku" she mentions refer to the "outer" and "inner" shrines of Ise Jinguu, perhaps the most prominent Shinto shrine complex in Japan. Unlike many shrines, the grounds are typically closed to public access, and the buildings are ceremonially rebuilt every 20 years, without the use of any nails.
