MY New Book on The Battle of Sekigahara OUT SOON!

In a time of plentiful bleak news, it is a wonderful feeling to have some Good News to finally report on. My seventh book, a non-fiction account of The Battle Of Sekigahara is set to be released in September by UK based military specialist publishers, Frontline Books, an imprint of the respected Pen & Sword Publishing group.

Pre 0rders are already being accepted!

My first book on the Battle of Sekigahara was published in 2014 after nearly 15 Years of research and was at the time THE most detailed book on the battle available in English. Since then, having been made the Sekigahara Tourism Ambassador, meeting and working closely with many professors, researchers and members of the Sekigahara Board of Education has opened up new lines of research and the discovery of so many more fascinating details, and having a greater understanding of the mechanisms of the battle meant that a new version was required.

While some parts remain similar, they have been altered and updated. New information, more detail, some fascinating discoveries made related to the battle while researching other topics and warriors who took park have been included. Many of the traditional “stories” associated with the battle have been analysed and commented on.  Although there are less maps and photo illustrations in this new hardback book, the quality is better, the information more interesting and far more revealing.

I hope history fans will enjoy it.

Making a Complicated Story Simple, Understanding Sekigahara.

One of PPF’s recent projects was the creation of a video package for Gifu Prefecture designed to explain the Battle of Sekigahara to the English speaking world. The Battle of Sekigahara was the largest samurai field battle, fought on October 21, 1600, and saw the deaths of an estimated 30, 000 samurai in a six-hour close-combat skirmish.

Video titles, Understanding The Battle of Sekigahara.

There wasn’t a huge budget, certainly not for the grand scale movie like re-enactments I initially envisioned, and so the challenge came to be how to show and explain the complicated political history leading to the battle, how the nation came to be split into two warring factions, who took part, how and why they came together at Sekigahara, the actions and results of such a large battle, as well as introduce the key players involved.  This had to be achieved in the simplest, yet informative and entertaining way.

It had to be informative, it had to meet certain standards, importantly, it had to tell the story of Sekigahara, simply, distinctly, and for an audience unfamiliar with the battle and characters involved.

I do a number of TV shows for NHK World, including Ninja Truth and Castle Quest. The production team I work with are not only very professional, but have become close friends. As such, my first thought was to secure their services in order to achieve the best possible result.

Being a history fanatic, deeply entrenched in the subject, as is often the case, I was too close to the subject matter. Thankfully, being friends, the producer and director were able to take my ideas, scripts and vision plans and help forge them into an easy to follow three-episode video package, Understanding the Battle of Sekigahara.

It meant three full days of video shoot in the hot, sultry Japanese summer, doing segment by segment but not necessarily in the order seen, but once edited, blend together seamlessly. Further recording sessions and mixing was done in Nagoya and the end result is pretty good considering the restraints.  Have a look at the clips, and enjoy.


史跡に設置された解説看板の英訳をはじめ、小和田哲男先生が監修された「必見!関ケ原」の英訳や岐阜関ケ原古戦場記念館・館内の英語解説文など、さまざま担当させていただきました。その集大成とも言えるのが “Understanding, Battle of Sekigahara “の制作監修です。





今回の動画制作にあたっては、どの映像制作会社に依頼するか検討した結果「外国人向けの動画制作」の実績を持つ会社、そして楽しく一緒に仕事ができ、なおかつ世界クオリティの映像が制作できる会社ということで、NHK WORLD「NINJA TRUTH」「CASTLE QUEST」(僕は、ナビゲーターとして出演)で、ご一緒している千代田ラフトさんに依頼。万全の制作チームで撮影にのぞむことができました。このチームなら、さきほど書いた「外国人向けの動画を制作する際の重要なポイント」も、すぐに意図を理解してもらえます。(日本人向けの動画しか制作したことがないチームだと、まずはこの部分の共有だけで、けっこう時間がかかります)




岐阜関ケ原古戦場記念館のロビーでも放映はされていますが、タビマエの海外の方々に見ていただけるようプロモーションしていく必要もあります。(Sekigahara と検索する外国人は、まだまだ少ないので、このあたりも工夫が必要です)

Hikone Castle App Press Release

Was at National Treasure designated Hikone Castle in Shiga Prefecture today for the press release of the ” National Treasure Hikone Castle Explorer” App, produced by my company, PPF (Past Present Future Ltd.) and the OTB, (Omi Tourism Board) as part of the Ministry of Cultural Affairs’, Cultural Properties, Multilingual Commentary Maintenance Project.

With Ms. Kojima of the Omi Tourism Board at the press release of the National Treasure Hikone Castle Explorer App.

The main features of this entertaining and informative National Treasure Hikone Castle Explorer Apps are;


• Video Presentation. In the app’s video section, I guide visitors through the castle’s many ingenious defensive features and reveal the secrets of Hikone Castle, it’s highlights and key points mostly often missed by tourists, and with the use of CG, show you how the castle looked in the days of the samurai. There are 10 video presentations in the App, and these can be enjoyed as a virtual tour of Hikone Castle at home, or watch it as you visit the castle site itself.


• Siege Game. The App contains a game where you can test your skills attacking Hikone Castle at 4 different points. As you progress, the play experience difficulty level increases. The CG used in the game is a must-see! The game can only be enjoyed within the grounds of Hikone Castle to make it an even more realistic experience.


• Map Screen. Navigate your way around Hikone Castle and read explanations of Hikone’s features and history. You can also follow Hikone Castle Museum information from the map screen.


• Samurai Helmet AR Photo. Take photos of yourself, friends and family wearing the AR samurai helmet of Hikone Castle’s first feudal lord, Ii Naomasa.


• The App is available in four languages: English, Japanese, Simplified and Traditional Chinese.

Tablets with pre installed apps can be rented at Hikone Castle.

This app is mainly targeted at European, US and Australian tourists, so instead of simply translating from Japanese to English as is usually done, we started by creating it in English first to meet the needs and understanding of the target tourists, and later translated my written scripts into Japanese and both simplified & traditional Chinese.

As you walk around Hikone Castle you can discover, and better understand the highlights of Hikone Castle, the ingenuity of defenses, its key points and splendor.

This “National Treasure Hikone Castle Explorer” App is available for anyone anywhere to enjoy. Naturally, some features, such as the Siege Game can only be enjoyed at the castle site itself, but the rest can be downloaded via App Store or Google Play and enjoyed as a virtual tour of Hikone Castle at home.
