Kenzo Tagawa, 61, a leading New Testament scholar, finds the sales of his latest book ‘‘encouraging’’ and ‘‘surprising.’’

His latest scholarly work — more than 700 pages — has undergone a seventh printing in six months since its publication and has found its way to some 10,000 readers.

‘‘For a book of this thickness and price (¥8,000), it is quite a phenomenon, ’’ Tagawa says.
