When Louis Vuitton merged with Moet Hennessy, a huge conglomerate, and formed LVMH, there were concerns that the LV tradition would be lost in the ever changing fashion world. But Louis Vuitton used the publicity to their advantage by keeping their core values unchanged and by adjusting to the times.
In 2003, Hata wrote the widely read book, Louis Vuitton Japan-The Building of Luxury, which was initially published in Japanese but later translated into French and English. The book covers the twenty eight years of Hata's experience from the time he joined Louis Vuitton to take over a brand that, at that time, lacked an identity and was little developed in Japan. He turned it into the most sought after brand in Japan. This development was instrumental in giving Louis Vuitton a "new breath of life". This book is full of creative and practical ideas.
