The Micah no jikan book ...
is now available, and I see from the Amazon.co.jp website that it can be shipped to any country.
The full title is 芝草科学とグリーンキーピング (マイカの時間 The BOOK). In English that is Turfgrass Science and Greenkeeping (Micah no jikan The Book).
This book is the culmination of a long project, started in 2008, writing monthly articles about turfgrass science and greenkeeping for ゴルフ場セミナー. From those articles, I’ve selected some of my favorites, read and reread and arranged into chapters, and now we have this book. I hope these can be available in English sometime. It is some interesting material on a wide range of topics: greenkeeping in general, soil water, organic matter management, fertilizer, golf course playability, and more.
