About THT Harmony
THT Harmony is a support service for Japanese individuals living in the United States.
Our Two Pillars of Support:
End-of-Life Planning Life Concierge Services
We help you organize the complex and interconnected challenges of healthcare, caregiving, legal matters, finances, and emotional well-being, creating a foundation of peace of mind for your future.
- End-of-Life Planning
Using our original end-of-life planning notebook, "Harmony Journal™," we help you organize information to prepare for the future. Together, we'll explore U.S.-specific healthcare and insurance systems, senior living options (such as assisted living and nursing homes), the possibility of returning to Japan, and cost considerations—taking one step at a time toward a secure future. - Life Concierge Services
We provide compassionate support to help you navigate daily concerns and procedures related to healthcare, caregiving, finances, and everyday life, bringing you peace of mind.
Both services are grounded in Trust, cultivate Harmony (peace of mind), and walk alongside you and your family with Togetherness.
In October 2025, we rebranded from "Aichan to Seikatsu Support, LLC" to "THT Harmony, LLC." While our name has changed, our commitment to providing thorough, attentive, and sincere support remains the same — now offering an even broader foundation of peace of mind.
【Additional Services】
For those looking to start their own business, we offer Startup Personal Coaching Services.
What Makes THT Harmony Different
No matter your age or health challenges,
living with security and being true to yourself is a fundamental wish we all share.
What I value most is not simply "helping," but walking alongside you
— listening to your thoughts, thinking together, and moving forward together.
Even with complex matters like healthcare, tax, and legal issues,
I always begin by listening to your story.
Then, step by step, I help arrange the support you need in a way you can trust.
My Experience and Credentials:
- Licensed healthcare professional in both Japan and the United States
- Certified 終活アドバイザー（End-of-Life Planning Advisor）
- Extensive experience in dementia care and geriatric medicine
- Experience with end-of-life care, Power of Attorney (POA), and trustee responsibilities
It's not just credentials — it's the hands-on experience of supporting individuals one by one that allows me to honor each person's wishes and guide them toward peace of mind.
That is the strength of THT Harmony.
Please feel free to reach out
"Having this person by my side gives me peace of mind."
I strive every day to be a warm and trusted presence so you can feel this way. It would be my privilege to help you live with a sense of calm and security.
