In 2015, as many as eighteen million people visited Japan. Starting with Tokyo, many cities in Japan continue to become more internationalized, as communities of people from other countries grow all over the nation. Our island nation, which once closed its doors to the outside world, is now opening up day by day, and while on one hand the deepening of exchange with foreign nations is good for Japan, it is a fact that problems with visitors from overseas are also increasing. While it is a splendid opportunity to look beyond national borders and strengthen connections with other countries, it can be difficult to deal with the problems which also cross those borders, and currently many of these issues are not receiving proper attention. Through our investigation business, we contribute by helping to build a safer and more comfortable life for those foreign visitors who wish to participate in our country.
