It's still hot in Tokyo. The maximum daytime temperature is over 30 degrees Celsius every day. Because of the COVID-19 calamity, I refrain from non-essential and non-urgent outings. Instead, I searched my hard disk for the previous cool photos for a change. Please look at the following image.
Art Aquarium Museum is a cool spot in Tokyo. I visited there with my family just after its opening. There are numerous goldfish bowls in the museum. Different from educative museums, these goldfish bowls are artistically illuminated. Some people comment that the goldfishes are pathetic because of the strong lighting. I'm not a specialist, so, not in a position to comment on the issue, but at least, the goldfish bowls looked beautiful, fantastic and cool.
To get to Art Aquarium Museum, the nearest station is Nihombashi on the subway Tokyo Metro-Tozai line. Taking this opportunity, I'm going to show you a train, EMU JR East E231-800 series, operated on the Tozai line. The E231-800 series was launched in 2003. 7 sets, 70 cars in total, were built by Nippon Sharyo and Kawasaki Heavy Industries. The light and dark-blue colored stripes are good features of this train. As you know, light-blue is the line color of the Tozai line. The E231-800 series is directly operated from the JR East line onto the Tokyo Metro Tozai line. With regard to the technical specifications, the acceleration at start-up of the E231-800 series is 3.5 km/h/s, which is the highest among the E231 series group trains.
