The gradations in color created by light and shadow are rendered in a pop art-like style re ecting the summer spirit.By Yusuke Kitajima (woodblock artist)Completed the graduate course in block printing at the Musashino Art University in 2014. He draws on a unique method that com-bines the techniques of woodblock printing and monotyping to create a single unique print, using familiar everyday items as subjects.The cover of this issue features the artwork of a state-of-the-art hearing aid. The inside of the front cover features a photograph of an original-style hearing aid. Hearing aids have changed dramatically since they were first introduced. Today, the most advanced hearing aids have shrunk to less than one-tenth the size of the original ones. In place of an empty funnel, we find ultra-compact precision components packed closely together. Now, hearing aids are even offered in an assortment of colors. (Ueta)People tend to smile without realizing it when they talk about their dreams, a smile likely to catch on with those listening. The world in 2050 described in our new feature “FROM NOW ON” is a splendid place where everyone can be happy. Rion is steadily moving forward to help create such a future. (Hagiwara)I’ve been on the staff of the Manga section for a while. I felt a bit anxious about the shift in focus from introducing our products to how our customers use them, but my interviews with users turned out to be great experiences. I’ve learned things I wasn’t aware of. And I’ve heard some telling phrases. (Nakamura)Interviews have helped me realize the importance of tackling a challenge enthusiastically, with a determination to achieve progress and innovations. I’ve been exposed to diverse views and ways of thinking. The contents of this journal present an opportunity for our readers to see diverse aspects of our company.
