I am Akihiro Teramachi, President and CEO of THK. I would like to share with you the overview of the financial results for the fiscal year ended in December 2022. Please turn to page 3. Consolidated revenue grew 23.7% year-on-year to JPY 393.6 billion. In the industrial machinery business, demand was strong in all regions, mainly driven by growing semiconductor-related demand, progress on automation and robotization, and EV-related demand. Against such backdrop, we were able to steadily translate this demand into sales as a result of our ongoing efforts to increase production capacity. On the other hand, the automotive and transportation equipment business was impacted by the decline in vehicle production caused by the shortage of semiconductors and other parts, as well as lockdowns in China and the situation in Ukraine.
Despite the operating loss in the automotive and transportation equipment business stemming from the auto production cutbacks, rise in steel prices, and the resulting impairment loss, the consolidated operating income increased 13.8% year-on-year to JPY 34.4 billion thanks to the revenue growth driven by volume and weaker yen in the industrial machinery business. As a result, both revenue and operating income, excluding the impact of the impairment loss, exceeded the initial forecast. Next, I would like to explain the sales breakdown by region on page 4. Due to the factors mentioned in the previous slide, sales increased significantly in each region compared to the same period last year. Let me go through the operating income on page 5. First, I will explain the factors behind the increase and decrease in operating income in the industrial machinery business compared to the previous fiscal year.
The factors that pushed down the operating income included JPY 8.5 billion of fixed cost increase, such as labor cost and personal expenses stemming from higher sales. The following are the factors contributing to the increase in profit. JPY 16 billion from higher sales and higher volume, JPY 1.6 billion from variable cost ratio, JPY 6.6 billion from forex, and JPY 0.3 billion from other income and other expenses. I would like to explain the changes behind the operating income for the automotive and transportation equipment business on page 6.
The profit decline was caused by the JPY 0.6 billion fixed cost increase, the -JPY 3.3 billion impact from the change in variable cost ratio due to the price hike of steel, among others, as well as -JPY 13.3 billion in other income and expenses, including impairment loss. On the other hand, profit was higher thanks to the JPY 4.2 billion volume impact from higher sales and JPY 1 billion impact from FX. I will explain our efforts in the automotive and transportation equipment business, including the improvement in profitability later in the presentation. Page 7 is a snapshot of our balance sheet. Total assets increased by JPY 44.2 billion year-on-year to JPY 560.3 billion.
I will skip the details given the interest of time, so please have a closer look at the figures at your convenient time. Next, let's move on to the key measures. Please turn to page 9. There's no change in our pillars of growth strategy, namely full-scale globalization, development of new business areas, and change in business style. We will further expand our business domains under our vision of becoming a manufacturing and innovative services company. In addition, as basic prerequisites for advancing these strategies, we are strengthening sustainability and ESG further and striving to be creative with our business. Page 10 illustrates our key initiatives in both businesses under the growth strategy mentioned in the previous slides. Let me start with the industrial machinery business on page 11.
As you can see, we are promoting the THK DX Project so that personnel freed up by reducing the person-hours spent on routine tasks can be redeployed to higher value-added operations to expand sales. To advocate these initiatives, we continue to work on further advancement of Omni THK, introduction of various ICT tools and structures, and development of digital human assets, the third point being the fundamental basis of the other two measures. Please turn to page 12. OMNI edge is capable of going beyond simply detecting predictive failure signs of parts. It is an IoT service providing solutions that can contribute to improving the overall equipment effectiveness, or OEE, by reducing various losses that occur at manufacturing sites. OMNI edge is growing as a platform.
Far, we have provided a solution for linear motion components as a first phase and the solution for the rotary motion components as the second phase. Now we have started to offer Tool Monitoring AI Solution as a third phase. Let me elaborate on the new service on page 13. Tool Monitoring AI Solution enables highly cost-effective operation through optimizing tool life, reducing tool replacement costs, and reducing rework losses when machining defects occur. The data collected from sensors is automatically analyzed by AI to detect abnormalities, and the accuracy improves with repeated use. We will continue to develop and introduce new solutions to reduce various types of losses in order to maximize the overall equipment effectiveness. Please turn to page 14. I have presented our new services, such as Omni THK and OMNI edge.
In terms of products in existing areas, we are introducing high-precision products for semiconductor manufacturing equipment and others, which requires increasingly higher precision. At the same time, in new fields, demand is steadily expanding in areas such as those shown on the slide. Please turn to page 15. In the consumer goods application, we will further enhance our lineup with products that do not require high-precision and are reasonably priced, but still maintain the characteristic of high rigidity, smooth movement, and high durability. The 2D slide ATG and ARG are suitable for sliding parts, such as for railway carriage doors and car seats. The 2D slide UGR is ideal for kitchen lifting mechanisms and assistive vehicles, among other applications. The rod actuator CREST 6,000 is used in various situations around us, such as for medical and nursing care beds, electric recliners, and office fixtures.
We have also launched a variety of new products that contribute to automation and labor saving. Please turn to page 16. The Cylindrical Coordinate Module MLS automates linear and rotary motion with a simple mechanism. The Picking Robot Hand System PRS automates picking operations in distribution centers. The Rotation Module RMR is a module product ideal for robot joints. The demand for automation and robotization steadily expands in different applications, we will continue to launch new products to fulfill those needs. Shown on page 17, we are expanding our global manufacturing capabilities in anticipation of medium to long term demand growth in the industrial machinery business. First, THK India started its operation in November 2021. The land area is 205,000 square meters, and the first phase of construction of the plant and the office building was roughly 37,000 square meters.
The plant has already begun full-scale production, and we aim to reach operation at full capacity by the end of this fiscal year. The new factory for THK's Changzhou expansion project was completed last June and is in operation. Approximately 15,000 square meters was added to the production floor space, mainly manufacturing actuators, units, and their own equipment. Expansion work is currently underway at THK Liaoning, intended to enhance LM Guide and actuator production. The building was newly completed in December 2022, with some other construction work remaining. The entire building is 25,000 square meters and full-scale production will begin after the Chinese New Year. In Japan, THK NIIGATA was also expanded, and the operation commenced in November 2022. This facility was expanded by 7,500 square meters and manufactures parts for robots, mounters, and medical equipment.
We will continue to consider the acquisition of sites for plant in Japan, as well as expansion of Gifu plant. Let me update on the progress of how we are reorganizing the automotive and transportation equipment business on page 18. We recorded impairment losses in the automotive and transportation equipment business as challenging business environment remained unchanged. I would like to once again explain the overall initiatives we announced in August last year, as well as the progress so far. First, we implemented the recovery plan and achieved cost reduction of JPY 1.7 billion in FY22, as illustrated at top left. In our pursuit for profit-oriented management, the effect of discontinuing unprofitable product is starting to come through and have now amounted to JPY 40 million.
Price negotiations to pass on the cost increase to customers, including the option of potentially withdrawing from the business if agreement is not reached, are progressing smoothly, and we intend to further enhance these positive impacts. While working on these initiatives, we allocated some fixed cost spending to the production of industrial machinery products and manufactured JPY 1.1 billion worth of products in FY 2022. There's a further increase in FY 2023. As a result, we return to profitability in the October-December quarter of FY 2022. In FY 2023, we will strive for continued profitability. From FY 2024 onward, we will aim for profitable growth through the expansion of next-generation product launches and other initiatives, as described on this page. Let me offer you more details on our next-generation products on page 19.
The volume for Integrated Brake System is steadily increasing. We expect to ship 4 million units per year in the medium to longer term. Various new product developments, including units for active suspension and mechanical level control units, are in progress and have begun to be adopted by customers. We will continue to expand our product lineup to support the CASE application over the medium to long term. I would like to talk about ESG and sustainability on page 20. Based on the concepts shown on this page, we are pushing forward various initiatives to realize a sustainable society. In addition to supplying linear motion products that contribute to energy conservation, we believe that services such as Omni THK and OMNI edge, which help our customers improve their productivity, can also make a significant contribution to sustainability.
As I mentioned earlier, OMNI edge, in particular, not only helps visualize the operating status of our products, but also minimizes the amount of lubricant oil and energy consumed, and minimizes the loss caused by machine breakdowns. These all help to prevent waste from being generated in our society. Therefore, we believe that we can make a stronger contribution to society by providing both hardware products and the service solutions. It has been quite some time since the concept of IoT became a topic of high interest. In our definition, IoT environment does not necessarily require new equipment or new systems. It can be easily built by attaching sensors onto existing products and connecting them on an online platform. We are trying to provide a mechanism that will enable the instantaneous conversion to IoT of all kinds of equipment that is currently in operation in the field.
In such a way, we will continue to add services with high value proposition, and together with our products that can contribute to the society, we hope to delight many customers and contribute to a sustainable society. This is our basic philosophy, which we describe as a manufacturing and innovative services company, and we will continue to promote various initiatives. Please turn to page 21. In order to align our organizational structure with the social environment, we established a Sustainability Committee in October last year to further promote activities related to sustainability. Most recently, the Sustainability Promotion Subcommittee structured under the committee has been working on information disclosure proposals in line with the TCFD recommendations, re-identification of materiality, and consideration of actions and KPIs to resolve those materiality. We will continue our efforts to achieve sustainable growth.
Next, let me turn to the full year earnings guidance for FY 2023. Page 23 illustrates the current order trend in the industrial machinery business by region. As you can see, orders are on a downward trend, but they have already hit the bottom. Although we have not factored this much into our forecast for the current fiscal year, we expect a strong recovery in China and other markets going forward. Please turn to page 24. Based on the information I have explained so far, we are projecting revenue of JPY 360 billion, operating income of JPY 30 billion, pre-tax income of JPY 31.6 billion, and net income of JPY 22.4 billion for FY 2023.
In the current fiscal year, while strengthening cost control to prepare for a short-term adjustment phase, we will also augment our measures in place to steadily capture demand in the upcoming recovery phase and actively pursue various initiatives to achieve medium to long-term growth. Thank you very much for your attention.
