Sunmark Publishing Rights Highlights
and NEWS Mail--September 2017 Issue

Hi. I’m Taku Hirasawa, an editor at Sunmark Publishing. Recently, a low carb diet has become a trend in Japan, and I decided to join it since I edited a related book the title of which is The Best Eating Habits That Changed the Lives of Top Executives. The biggest and the hardest point for me beginning the diet was that I had to stop eating the food I love more than anything else…RICE. Rice has been my favorite food from childhood, but what is unfortunate was that it’s a typical carbohydrate. Actually, I didn’t have to be so strict, but I made my decision and own rule to make this challenge more successful. Specifically, the rule is to abstain from rice until I make a bestseller which sells more than 100,000 copies. Until I achieve that goal, I can never taste my favorite food again. I’m hoping for the day from the bottom of my heart that I’m released from that vow, so please let me know if you have any book in mind that’s good to translate for the Japanese market.

If you have any questions or inquiries about this NEWS Mail, please contact Ms. Shino

12hen_rurikoHello, my name is Ruriko Ikeda. I’m an editor.

My hobbies are reading and running. These days I’m also into triathlons, and I participated in a race held in Taiwan. Someday I’d like to run a marathon race overseas too. At that time I would be happy if I could see you all.

The first novel I edited, Before the Coffee Gets Cold, reached sales of 500,000 copies in Japan and now is a bestseller in Taiwan, too. I’m very happy to hear that.

04hen_shinAs I’m interested in the mechanism of the human body, most of the books I’ve been editing are about health and sports– though my books about vegetables became bestsellers, too.

One thing I try to do in editing is think about how I can present difficult topics in easily understood ways.

The accumulated number of books I’ve edited has sold more than 5,000,000 copies. With luck and sensibility I’ve been surviving in the publishing industry.

We made a trip to Taiwan in July to introduce some of our books.

Synchronicity Management

by Yasutaka Horiuchi

ISBN978-4-7631-3624-4 C0030

266 pages / May 2017 / 1,400 yen (w/o tax)

A method that’s changed over 4,000 people's lives.
Reveal what’s hidden inside you!


Businesspeople, artists, creators, inspirational figures, and downright lucky people all have one habit in common. That’s the habit of placing importance on coincidence and insight when making life choices. This book explains how to use synchronicities to inspire your actions.


The method is called synchronicity management.


There are three steps to awakening your heart, mind and body. By following them, you’ll be able to escape the many constraints you’ve set for yourself, whether related to human relations, finances or lifestyle. Paying close attention to coincidences and inspirational signs will help you realize your dreams. This will help you get everything you’ve ever wanted in the most unexpected ways, like getting married to the person of your dreams, or landing the job you’ve always hoped for.


Rather than trying to manage people, time, and money, using your insight to manage synchronicity will help you transform your life.

From the editor "Nekoka"



The author and I both found it interesting that a book on synchronicity turned into a book about a personal awakening. This book discusses synchronicity from an all-new perspective. Throughout the editing process, mysterious coincidences were taking place almost daily. I truly believe that things will fall into place for you as soon as you start reading.

From the editor "Umechan"



I also had trouble talking in groups. With one person, I can just be that happy-go-lucky guy from Kansai to break the ice, but in a group that doesn’t always work. I figured there must be a clear, evidence-based explanation for why socializing is more difficult in large groups, so I was intrigued when Takenori Iwamoto told me there is actually a neuroscientific reason.


This book goes into detail about why that added fourth person makes things difficult. The author also provides the tools and methods you’ll need to improve your social skills. What’s more, it’s all very easy and fun to read. This book will prepare you for that dreaded party, meeting, and any situation where small talk is unavoidable.


Takenori Iwamoto

Takenori Iwamoto is a marketer and a board-certified behavior analyst born in Shizuoka Prefecture, Japan, in 1975. Along with working in the marketing department of a railroad company in Shizuoka, he is currently studying human decision making and behavioral traits at Kyoto University’s Graduate School of Engineering. He has recognized over 300 billion behavioral patterns and has also conducted group interviews with more than 1,000 people.


He began studying the brain after his daughter suffered brain damage in a traffic accident. This led him to develop a unique rehabilitation method, which in turn led him to discover that people’s behavior is related to the brain and heart. He then conducted further research into applying the structure of the brain to marketing and presentation layouts.


Putting his knowledge of how the brain works into practice, he increased sales at a supermarket run by his railroad company by seven times. He also helped the IC commuter train pass ownership rate in Shizuoka Prefecture to exceed 50 percent.


Outside of his business, he gives lectures on his research about human behavior, focusing on such themes as why we buy certain things and why we change our behavior. He is also a certified psychology counselor.
