They only created one calendar for 2015. The title is shown below and this title is also still available through Amazon and other book sellers.
Japan Outdoor Scenes 2015 Calendar
They also only created one calendar for 2016. The title is shown below and this title too, is available through Amazon and other book sellers.
2016 Calendar - Japan Outdoor Photos
The year 2017 was the final time they created a calendar of photos taken in Japan. That one was entitled 2017 Calendar - Japan Outdoor & Nature Photos. It too is still available for sale through Amazon and other book sellers.
The problem with calendars is that they are hung on the wall, written on, abused and finally they are thrown away. This book, therefore, includes all of the photos shown in the above listed six different calendars in a nice book form that can be kept forever so that the photos can be enjoyed again and again without being thrown away at the end of the year. Each photo is shown with a very brief description that explains what it is and where it was taken.
You will note that as there are six calendar titles shown above, there should, therefore, be six photos for each month. This is generally the case, but not always. In some cases the authors selected fifteen or twenty of their best photos taken during the year to consider for inclusion in the calendars, but of course a calendar can only include twelve images and they had to make some tough decisions about which photos to include in the calendar and which to set aside for use at a later date. This book includes some of those photos which had to be set aside for use at a later date. When they show you a photo which was not used in a calendar they indicate that it was not used.
