As siokan stated above, there is simply no chance whatsoever that 浅野照子 could be the author's name. In Japan, textbooks for elementary schools are always written by groups of people and their names aren't shown on the covers.

Even if that were the author's name, it would not have been hand-written in the cursive style on each copy like that in the pic when they had to print this book in the order of hundreds of thousands of copies.
