I visited the Ueno Zoo today.
In the afternoon, I checked out of Park Side Hotel and took a JR train to Urawa and checked into Urawa Royal Pines Hotel. This hotel is quite luxurous. My hotel room has a fax machine, high-speed ADSL connection and an electric toilet. I booked it on the hotel website and paid only 1100 yen a night for it, including breakfast, service charge and tax.
In the evening, I went to Saitama Kaigan to attend a Mahler concert performed by the Tokyo Metropolitan Symphony Orchestra conducted by Bertini. They played the Adagio from Symphony no. 10 and das Lied von der Erde.
