Thank you for visiting our website. We have been offering IT services with a focus on the computer system development since 2002. Our society has changed drastically over the last 20 years. That is, IT innovations have advanced our society and our lives has reshaped. We believe that we are in the brand-new era that is not the extension of our past. Especially, in the IT Industry, it can be a fatal mistake if we keep thinking on the basis of what we have done before. In this age, we have to distinguish between what will change and what will not. 17 goals from SDGs from the United Nations were set as public value all over the word and we are all required to follow them. Needless to say, in business, we have to create a new period along with those goals shared over the world.


4thWAVE, Ltd. has been offering services specialized in the cruise industry since its establishment. Namely, domestic ship companies, Japanese branch of foreign ship companies, domestic GSA on behalf of foreign ship companies, and domestic travel agents have been using our core system CruiseWorld for their business operations. 14 ship companies and GSAs from many countries such as US, Italy and UK (50 ships in total) have been managing their reservations from Japan with our service CruiseWorld.

1. We offer systems that enable cruise tourism to perform at its full potential

We had been engaged in the system development of the cruise industry since 1997 and established 4thWAVE, Ltd. in 2002. As the industry grew, various social, social, and environmental changes have happened.

Our society have been moving forward along with those changes. For instance, in the ICT industry, with new idea s and technologies, the fourth industrial revolution has begun.

Industrial structures of our society can no longer be simplified as more complex factors are involved. We believe it is essential to spot things from various perspectives in order to develop a system that can adapt to changes and take advantage of them as opportunities.

Forecasting what will change and will not, we will offer the best solutions. We will establish our core competence on the basis of our experience over the past 20 years and will strive to provide the competency to the all involved in the cruise tours.

2. We make digital services that can deliver the essence of tourism

The essence of tourism is deepening our identities on the basis of the influence on memory, behavior, and the way of living though the interaction with people and nature. We all find ourselves changing through stimulus from pre-travel time to post-travel time…we will aim to develop such a new digital service that enables us to create better relationships with other people and things.



Make the world peaceful through tourism

There are so many types of people who have various sense of values in the various environments. Travelling is, we believe, enjoying our difference and touching what we do not have in our daily lives. Through that process, we might be impressed, or sympathize, or encounter new sense of value, or grow our minds. Development of human beings has been driven by the delight of knowing what is different from themselves.

As a result of tourism, a sustainable peace where we can respect our differences will be established.

About our company name

In 1980, Alvin Toffler, an American writer, published his best-selling book The Third Wave and delivered such an sensational idea that Nippon Housou Kyoukai (NHK) made some special TV programs. The development phase of human society which he focused in his book turned out to be true and we cannot help but feel that we are shifting from the third to the fourth wave. We will strive to offer new value, keeping to foresee what the next wave will be.
