If I were Sei Shonagon
I’d put this in my pillow book -
Three lovely things:
A pickled plum; a paper crane;
A Toto Washlet toilet.
(Click on the videos for the full son et lumiere performance.)
Yes, I know it's an extravagance, but once you've sat on a Japanese toilet, you can't go back. Indeed, you don't even want to get up: Haruka tells me that piles are a problem in Japan because people just bliss out on them all day.
It's also, I tell myself, an investment, although probably not a tax-deductible one. In the medium term I want to let a room to Japanese students, and this will be a draw, I fancy.
