The technology that intrigued me the most and I belive a lot of other people on our trip were the mobile phones of the Japanese. These phones, also known as Ketai, can do unimaginable things that would excite, intimidate, and astonish an average American citizen.
While most look square and very bland on the outside, when they open up and show a display of a movie or TV show they are extremely sleek, sexy and beautiful. Every Ketai that we saw had a screen that appeared to be LCD and high def.
One example I can give is when our group was at sumo we witnessed these Ketai in action. We were sitting up in the nosebleed section far from the main mat and it was difficult to see unless you zoomed in with your camera. Within ten minutes of sitting down ten or so Japanese people, ranging from school students to businessmen, pulled out their Kaitai, whipped open the screen, pulled out an antenna and watched the sumo match as it was happening right in front of us. Since it was difficult to see the mat they could watch instant replays streamed live to their mobile devices.
This type of technology has not reached the States yet and it will be a while before it does. In Japan they have had Super 3g for a while now and are working on a 4g network to be released within 2 years, while the US is just getting Super 3g with the new iPhone 3gS. The reason Japanese technology is so far ahead of US and Western civilization is because Japanese culture revolves around technology. Nearly everything the people in Japan do has to do with technology.
Japanese cell phones can also have software installed into them that relates to the Suica card. A Suica card which was invented by the JR Rail station, is used to get in out of out subway and train stations. A holder of the card can put on up to 2000 Yen ($200) and recharge it at a station when the balance is low. The JR Rail Research and Development Center in collaboration with several cell phone companies such as NTT Docomo, SoftBank, and KDDI have created a way to put a certain software in the Ketai in order for the phone to replace the actual card. Japanese Ketai holders will no longer need an actual Suica card as long as they have the updated software on their mobile devices.
The fact that the phones can now be used just as easy as an actual subway pass saves a lot of money and time for the citizens of Japan. No longer does a person have to spend the time to pull the card out of their wallet or purse as long as they have their Kaitai handy.
The last thing that surprised me most was the fact that almost everyone had a cell phone. 7 year olds sitting on the subway and people well into their 80s walking down the street all had cell phones. It was surprising if we saw someone without. It is amazing that the mobile market saturation rate is so high in Japan while in the US we struggle to get cell phones out to everyone.
It would be nice to see this type of technology not only come to the United States, but to be universally adopted. The Japanese seem to have an edge up on the world in the aspect of mobile devices and hopefully the world will follow suit.
