and NEWS Mail--August 2017 Issue

Summer is coming and people are starting to enjoy the outdoors and making last-minute schedules for their summer vacations.

For us in Japan, large firework displays are one of the popular features of summer. There are different fireworks depending on the area of the country, and here in Tokyo, the Sumida River Fireworks Festival is one of the most famous and large-scale fireworks festivals. About 20,000 fireworks are set off in this festival, and we can view the Tokyo Sky Tree (the world’s tallest broadcasting tower) and fireworks together. This year the festival is scheduled for July 29th. Usually close to a million people come to the event, so the stations nearby are always super-crowded, but this is all part of what we enjoy.

There must be different, unique ways to enjoy summer everywhere in the world, and we hope you enjoy this season of the year wherever you are!

I have produced three million-seller books so far, and the latest one is Even the Stiffest People Can Do the Splits With Ease.

I like Samurai dramas very much, but I have no Samurai spirit. Rather, I would like to have the ability to run away fast and hide like a Ninja. I am 46 years old.

I keep two dogs. The vegetables I like are potatoes and corn. I like producing books much better than reading them.

I am an editor who’s a tomato addict.  My hobby is reading books and magazines.

Especially when it comes to fashion magazines, I can’t help buying ten or more.

The reason I came to be an editor was motivated by my friend’s saying, “If you love reading so much, you should work for a publisher.”

3 Minutes a Day! “Neck Pumping” for Good Health

by Takashi Nagai

ISBN978-4-7631-3620-6 C0036

238 pages / April 2017 / 1,300 yen (w/o tax)

The latest health method that refreshes your whole body!


Only 3 minutes a day!

Heart and body health improve dramatically with neck self-care!


The neck has the important role of connecting the brain to the body. When your neck acts as a “plug” — in other words, when its muscles are stiff and blood circulation is stagnant — it has a negative impact on blood circulation in the brain. Since your brain monitors bodily functions and health, this could cause serious health issues.


This “neck block” is the cause of stiff shoulders, lower-back pain, irritation, anxiety and a lack of determination.


You could say, “Your neck controls your vitality.”

“Unblocking” your neck will revitalize your body!


In this book a popular Seitai (chiropractic) bodywork specialist, who has provided medical treatment and guidance to around 60,000 patients, introduces “neck pumping,” his own form of neck self-care.


“Neck pumping” involves rhythmic exercising of the neck muscles and stretching that stimulates blood flow.


Improve your health drastically by doing this easy, comforting exercise for only 3 minutes a day.

15hen_kuroI experience neck and shoulder stiffness from being hunched over my computer and manuscripts all year long. After trying neck pumping, I immediately felt better, and my neck and shoulder stiffness subsided. I encourage you to try it! This book also includes a cute cover and nice pictures.


Takashi Nagai

Takashi Nagai, born in Toyama Prefecture in 1982, is a Seitai (chiropractic) therapist who heads a Seitai school. He is also the COO of the Japan Enrichment Association. 


After graduating from the university, he began working for a venture company, but stress from hard work caused autonomic nerve damage. Losing his career to autonomic ataxia and the early deaths of his father and grandfather helped him fully realize the importance of good health.


After struggling with over 100 different rejuvenation methods, he decided to focus on Seitai after experiencing the dramatic effects of American chiropractic. He noticed the hidden strength of the neck in bettering health. His specialty is in autonomic nerves. In a span of about six years, he has treated over 600,000 people including professional athletes and other physicians.  He also provides “self-care” guidance to a number of patients who visit him from surrounding areas and overseas.


His own “neck pumping” self-care method has contributed to the rehabilitation of all of his clients. His methods are fast and easy, yet effective, and the benefits are easily obtainable by anyone. He is working hard to popularize these methods as much as possible. As an author, his works include A One-Minute Stomach Massage Will Change Your Life and Reset the Body to Eliminate Fatigue (both Jiyukokuminsha).

The “Trunk Muscle Reset Diet” That Top Models Have Kept Secret

by Kenichi Sakuma

ISBN978-4-7631-3621-3 C2075

95 pages / May 2017 / 1,000 yen (w/o tax)

As seen on MBS TV in Japan!
Lose weight effortlessly with models’ best-kept secret.


The amazing diet that has kept 30,000 people in shape, including Miss International winners and other celebrities, is now revealed.

○ Do 1 exercise for 1 minute

○ Decrease the frequency after 2 weeks

○ You can quit after 2 months


The secret to models’ effortless weight loss lies in their trunk muscles. “Model trunk muscles” is a term used to describe the muscles that top models use but most women overlook. Learning to use these muscles more will increase your basal metabolism and burn more fat. This will also help you to use all of your muscles more evenly, resulting in slimmer hips, thighs, arms and tighter abs.

And that’s not all. Your body will become accustomed to using the model trunk muscles,  meaning you can stop focusing on them in your exercises after a short time.


This book also provides eating methods to cope with a “stagnant routine” and “overeating” and promotes “urgent weight loss.”


You will no longer fail at a diet program due to a lack of a consistent routine or daily exercise. Obtain your ideal figure with the help of this book.

From the editor "Hasumin"


“Dieting is difficult because of the way I’m built.”

“I’m not young anymore. It can’t be helped.”


I don’t know how many times I myself have used these excuses for giving up on a diet. Kenichi told me that weight loss has less to do with what type of body we have and more to do with how we use it. I was surprised to hear that anybody can change their body with this dream diet. There is no longer any room for failure.
