Light and shadow in sightseeing

Tourist boom

Thanks to the strategic relaxation of the visa policy, tax exemption and the bold reforms of the Abe cabinet, the number of tourists and their economies are expanding day by day. The tourism agency has set goals for 10 years and 20 years from now, and aims to increase the number of tourists, travel consumption and foreigners by several times. However, how to achieve that is the question being asked.

Bias of tourist places

According to the Tourism Agency, accommodation for foreign tourists visiting Japan is concentrated in cities such as Tokyo, Osaka, and Kyoto. The concentration of the location and time of sightseeing in the urban area limits the benefits to the entire regions. In addition, if the number of tourist cities is limited, there is a concern that the repeater's return rate will also be low due to the narrowing of tourism resources.

Limits of advertising

In the tourist areas for a provincial city, it is very difficult to raise the name recognition. Although Kamakura and Nara are very famous domestically in Japan, most foreign tourists do not know them. In terms of cost effectiveness, it is also difficult to promote these provincial cities to foreigners visiting Japan.

Tourism 2.0

In order to deal with various problems in tourism, it is necessary to evolve from service provider-centered tourism 1.0 to user-led tourism 2.0. Tourism 2.0 collects and analyzes regional and user opinions at low cost, on a large scale, and in a timely manner, using UGC (User Generated Contents) by transmitting information on their own. UGC, which is generated based on the user's tourism experience, is an important source of travel planning, tourism resource rediscovery and promotion. Also, analysis and utilization of “tourism knowledge” from the user's point of view, such as, research on tourism knowledge mining has been actively conducted.

Spreading tourism pollution

While tourists have increased, dissatisfaction from residents against tourists has also increased. Although it becomes convinient to travel by renting private residences, the manners of tourists are being asked at the same time. In addition, it is also a problem that traffic congestion and noise on the road caused by crowded tourists will inspire dislike in local residents.
