Creating happiness with a future-focused perspective
Since our founding, Tristar has been guided by the principle of “cultivating trust rather than acting solely for profit”. We aspire to stand alongside our clients at pivotal moments in their lives and businesses, building enduring relationships over time.
Our business spans diverse sectors: property, trade and goods, and everyday life support. At first glance, these may appear disparate fields, yet they are united by a shared conviction: “bringing peace of mind to people and their daily lives, and building the future together”. Whether it is the utilisation of property for business succession, venturing into overseas markets, or services that support daily living- although each takes a different form, our destination remains the same.
Societal changes and customer needs are diversifying every day. Rather than fearing these shifts, we have embraced them by continually exploring new initiatives. Building on trust, we deliver solutions attuned to the times, providing reliable services to both corporate and individual clients.
The three stars within the Tristar name symbolise Trust, Challenge and Co-creation. Walking alongside our customers and local communities, adapting to the times while holding these three principles close, we move forward into the future.
Our aspiration is to bring peace of mind and prosperity to people’s lives through every one of our businesses. We believe that this accumulation will connect to the hopes of those who will lead the next era. We will continue to embrace challenges and remain a company that walks alongside you all.

WATANABE, Masafumi
