Do you often see wrap advertising trains in your country? In Japan, we often see flashy advertisements specifically on tram bodies in urban areas. Let's look at two examples on the Arakawa line of the Transportation Bureau, Tokyo Metropolitan Government (Toei).
The first example is seen on the side body of the 8800 series streetcar. You can see a yellow-colored polka-dot poster with cute mascot characters. The advertiser is a private university named Kagawa Nutrition University. It's a famous university for nutritional research established in 1961. As I posted before, Japan's population has entered into a decreasing phase. Universities can't keep their arms crossed in this situation. They are in competition to attract high school students, and have to improve their value. Otherwise, excellent students will select other universities. Kagawa Nutrition University is no exception. The wrapping advertising streetcar might be their last resort.
The second example is seen on the body of the 8900 series. You can see flashy vertical stripes of green, black and orange colors. The advertiser is a group of "rakugoka". Rakugo is a traditional Japanese comic storytelling. A rakugoka (a rakugo story teller) plays various people by himself (herself). This group plays rakugo on the tram of the Arakawa line once a month. The passengers can enjoy rakugo while boarding the tram. It'll be a relaxing time, and a wonderful memory for them. The fee is about 16 US dollars.
I hope you'll see a part of Japanese society from these wrap advertising trains.
