1998 - 2008

In the pivotal year of 1998, during the 10th year of the Heisei era, we embarked on a journey marked by innovation and commitment to excellence. During the early to mid-Heisei period, Hotel Management International Co., Ltd. was established, laying the foundation for our enduring presence in the hospitality industry.


The year 2007 proved to be a significant turning point for our company. In January of that year, AME Co., Ltd. was founded, symbolizing our expansion and adaptability in a dynamic market landscape. During the period spanning from November 2006 (Heisei 18) to July 2007 (Heisei 19), strategic acquisitions reshaped our business profile. HMI acquired the esteemed "Kitakyushu Prince Hotel" from Mitsubishi Chemical Corporation.

Furthermore, we innaugrated "Hotel Crown Palace Kitakyushu" and "Top Wellness Kitakyushu" in February 2007. These establishments not only enriched our portfolio but also set new standards in the realm of hospitality. Our dedication to business succession was evident in the acquisition and successful management of three facilities – "Nisshokan," "Umamatsutsuru," and "Momijitei" – from Juuhachi Bank.

Building on these successes, we introduced innovative concepts such as "Nisshokan Shinkan Umamatsutsuru" and "Nisshokan Bettei Momijitei," expanding our offerings to cater to diverse customer preferences. The subsequent year witnessed the opening of "Nagasaki Nisshokan," a testament to our continuous growth and expansion strategy.
