Nobuya Haramaki, M.D., Ph.D. |
Nobuya Haramaki M.D., Ph.D. is chief physician and director of the clinic,
and has practiced in Karatsu for over 13 years. Dr. Haramaki graduated
from Kurume University School of Medicine with an M.D. degree in 1987.
He started his clinical career as a medical doctor at the Department of
Internal Medicine in the Kurume University hospital. He then earned a Ph.D.
degree from the University. Dr. Haramaki worked as a researcher at the
University of California, Berkeley, in their Department of Molecular and
Cell Biology from 1992 to 1995. After returning from the US, Dr. Haramaki
continued his previous clinical and scientific work at the Kurume University
hospital. His clinical expertise is internal medicine, specializing in
cardiology. The main theme in his research was elucidating the mechanism
of heart attack by focusing on free radicals, antioxidants, and platelet
thrombosis (see Publications listed below). In 2002, Dr. Haramaki became an assistant professor of medicine at Kurume
University. He moved back to his hometown of Karatsu and started to direct
the Haramaki-iin in 2004.

Hobbies and Interests

|
It is Dr. Haramaki’s custom to walk his dog, Indy, every morning and evening.
Indy is a 5 year-old male poodle weighing 6 kg. Because they live in the
scenic area of Karatsu, they are able to enjoy several wonderful views,
such as that of the Karatsu Castle, the bridges at the mouth of Matsuura
River, the West and East beaches, and the Rainbow Pinery called “Niji-no
Matsubara”. The walking distance is almost 8 km, approximately 5 miles,
a day. Five years ago at the beginning, Dr. Haramaki started to take Indy
out for the walks, however, he now feels as though Indy is taking him out,
in order to maintain his health through daily exercise. Dr. Haramaki also
likes surf sports such as surfing, wind surfing, and stand up paddleboarding.
When he was younger, he went surfing frequently. Even in California, he
often drove across the bay area to Santa Cruz to go surfing. He loved the
Santa Cruz coast, a typical California coast, because he always felt that
the figure walking down the classic wooden stairs from the cliff with a
surfboard was like a scene from a surfing movie. Recently, because he is
too busy to seek good conditions for surfing, and since it is too tough
to maintain muscle power required for paddling into the waves, he has shifted
his interest from surfing to windsurfing. With windsurfing, it is easier
to adjust to the weather conditions, such as by using a big sail for light
wind or a small sail for strong winds, therefore, there are more chances
to have fun. If the wind is too light for windsurfing, stand up paddleboarding
is possible these days. Surfing is also possible using a stand up paddleboard
if there are adequate waves. The greatest thing is that most of the beaches
where Dr. Haramaki likes to pursue his surf hobbies are located within
a 15 minutes’ drive from his home. Although his priority on weekends is
to spend time with his family, he can easily find a couple of hours to
go to the beach. Thus, he enjoys the beautiful beaches of Karatsu while
using just a little spare time on weekends.
