In fact you only this book period because it tells you how to get around as well as defining what there is to detain a rail traveller in any particular place. We found it absolutely brilliant. I left my other guide books at home and slowly discarded brochures from JNTO as largely redundant.
The phrases in the back of the book were more helpful than a 3 month night school of Japanese 1 and the timetables are still fairly accurate. You can check these locally, on the internet before you leave, when you are there or have your nice Nagoya Hotel do that for you (Hotel Astria). All JR stations will help as well!
Back to the book however, what it doesn't tell you is really not worth knowing. We visited 2 listed steam attractions; the Locomotive Museum in Kyoto, impressive and the Senzu-Oigawa line even more so, including the singing conductor! Of the places it mentions, the Gold Leaf Museum is exactly as described down to the tea you will be served with tiny squares of gold leaf floating in it. There is usually some little thing you do not recall from the book, such as a little demonstration of what gold leaf really is like, which make this almost the perfect guide book.
Truly leave the rest at home and seek out only the very special extras if you must, such as "Walks in Nara" though we thought the 2 main things the book recommended for Nara were quite enough really, after all the Giant Buddha & the Lantern Temple are both poles apart and it was a hot day!
Will definitely look for another edition when we are next able to return to Japan.
