Born in 1981 at Kagoshima, and raised in Aichi, Japan.
Studied International Development from 2002 at King's College London.
After graduation, started internship at United Nations Population Fund
Vietnam-Hanoi office
and Asia Development Back Institute.
After working at investment fund company, establisehd HASUNA Co., Ltd on
April, 2009.
Currently deploying business mainly on Ethical Jewelry brand.
I have brought myself to dozens of countries until now, thinking what it is that I can do for this world.
Walking through places in Asia, Africa, and South America, I have faced some scenes which I couldn’t help turning my eyes from.
Could there be something I can do to make a change?
After over 10 years of hard thinking, HASUNA was the best answer I reached.
Searching the many precious people and things still hidden some place on this Earth, and polishing them up to beautiful jewelry…
I truly believe it would be wonderful if everyone, from producers to consumers, can become happy through the manufacturing of jewelry.
The jewelry will be filled with messages about the culture and beauty of the land the materials are produced, and the hearts of the people who send and wear the jewelry.
A piece of jewelry will finally come to see the light of day, after bringing the hearts of the many people involved, to the person who wears it.
That is why I believe a piece of jewelry has the power to make happy not on the person who wears it but all the people involved in producing it.
By jewelry with such infinite power, I would like to continue my efforts to fill this world with more smiles.




HASUNA’s ethical jewelry maximizes the happiness of all people involved in designing, supplying, producing, and the distribution process, and minimizes the negative impacts to the society and the environment.
Our ethnical jewelry contributes to the people, society, and the environment of countries in various regions, irrespective of whether it is an advanced country or developing country.
HASUNA’s jewelry is unrelated to all trades which may involve child labor, sources of money for disputes, and environmental disruption. The entire supply and distribution process is visualized to us.
We offer you jewelry which is radiant and suitable for bringing love and thankfulness to your loved ones.
