One major accomplishment we made during STAGE 1 was aligning the mindset and actions of all members of the Group, from the management team to employees. By considering the long-term goals and thinking in reverse about what needs to be done to accomplish them, each employee is now taking action with a greater sense of speed. Members of the executive team, starting with myself, have been visiting local offices to meet with employees, from those in the front lines to those at the managerial level, to discuss issues that are taking place. I have also been working with other Group employees to offer opportunities for dialogue on an ongoing basis. I am confident that these types of efforts have played a significant role in helping to align the mindset and actions of Group employees. Since my appointment as president, I personally have held dialogues with a total of nearly 2,000 Group employ- ees. I came to realize just how extensively and deeply the long-term goals and Corporate Philosophy are shared across the globe when we were faced with several crises for which existing rules were of no use. During the three-year period of STAGE 1, we encountered many unexpected crises, including large-scale natural disasters, a global pandemic, and supply chain disruptions. However, it was in these moments where I gained an understanding of how well our Group employees respond quickly and work together toward a solution and how an independent sense of unity is growing stronger among them.
In terms of business performance, we started to see genuine signs of the widespread adoption of the spray seat WASHLET in the Americas, which has long been an aspiration for the Americas Housing Equipment Business. TOTO has been importing WASHLET to the Americas since the 1980s. At that time, WASHLET gained very little recognition in the local markets. The value offered by WASHLET was not thoroughly understood, and consumers often confused it for a medical device. Throughout the years, we continued to make concerted efforts to create as many opportunities as possible to experience WASHLET and increase its level of recognition, including installing the product in the homes of employ- ees of local agencies so that they could explain to others its functions and value. Around the middle of the 2010s, social media became more widespread, and people who had visited Japan began sharing the experiences they had on their trip. In addition, more ways to purchase WASHLET emerged, including through e-commerce websites and major retail chain stores. These factors helped drive demand for WASHLET. Furthermore, the toilet paper shortages that started in 2020 due to the COVID-19 pandemic led to a surge in demand for WASHLET.
In light of this, we are now presented with an opportunity for WASHLET to be just as big of a success, if not bigger, than it has been in the Japanese market. Now that spray seats are on the verge of wide- spread adoption in the Americas, it is prime time for us to accelerate their promotion without hesitation. TOTO has spent many years refining the functions, design, and quality of WASHLET, and the cumulative total shipments of the product now exceed 60 million units. Moving forward, we will expand the market for WASHLET by drawing on the confidence and insight we have as a company that has provided the largest number of spray seats in the world. To realize greater growth in STAGE 2, we will review our allocation of capital and once again execute profit-oriented investments as we work to rapidly establish the Americas Housing Equipment Business as the main pillar for growth in the International Housing Equipment Business.
In addition, we believe that the Advanced Ceramics Business, which offers high-quality, high-preci- sion ceramic products in the field of semiconductor manufacturing equipment, is poised to make a giant leap toward growth, in the same manner as the Americas housing equipment business. As a new busi- ness domain of the TOTO Group, we have persistently taken on challenges and pursued various trans- formations in the Advanced Ceramics Business. As a result, we started to see signs of genuine growth in the business in STAGE 1 between fiscal 2021 and fiscal 2022. Before this time, however, we were unable to capitalize on market growth in this business, and this is something we must sincerely reflect on. The Advanced Ceramics Business differs greatly from the Housing Equipment Business, as it requires far greater level of speed. Our in-house structure, including for manufacturing, was unable to keep pace with the speed required. To address this situation, we started to pursue dramatic reforms in conjunction with the start of operations of the new building at the Nakatsu Plant in 2020, including the swift promotion of the transition to smart factories. As a result, our response speed increased, and we were able to establish a highly profitable foundation enabling the business to achieve an operating margin of over 30%. Although market conditions were sluggish in fiscal 2023 due to the so-called silicon cycle of the semiconductor industry, there is no doubt that the market will expand again as we head toward 2030. To build a develop- ment and manufacturing environment that can respond to the speed and sophistication of the semicon- ductor industry, and to capitalize on future business opportunities, we will proactively implement investment and rigorously promote essential preparations with a focus on the future.
Also, we expect to see significant market growth in the Asia and Oceania Housing Equipment Business, with strong economic growth expected in each country and region. In these ways, the growth segments of the Americas Housing Equipment Business, the Advanced Ceramics Business, and the Asia and Oceania Housing Equipment Business will serve as an engine that will drive the growth of the entire TOTO Group as we head toward 2030.
