We took the Shinkansen train to Okayama to visit the castle and gardens here. The castle was quite impressive and the gardens, said to be among the 3 best in Japan, very pretty and peaceful. The highlight of the day was my haircut though. The cutting was done quickly and efficiently and with a lot of care and then the man asked if I'd used a robot shower before, and then it became more interesting. Of course I hadn't and he said I shouldn't worry. He pressed a button and the hairdressing chair swivelled round, and I sat down on the contraption. Soon I was reclining with towels and water jackets in the right places and jets of water were spraying over my head in lots of directions with some force. With a few "oohs" and "ahhs" it was eventually over. Very nice and I'm sure my scalp has never been cleaner.
