These are probably the two sections I focus on the most. One of the things I particularly like, and I don't know if you've done anything similar, is to read round table discussions on a specific topic. Some U.S. publications do this. They are very, very interesting and seem to attract readers. If you put together a panel of experts on a specific topic, such as the stock market, on a quarterly or semi-annual basis, I think it would be stimulating and it could be a circulation booster.
People like to see how expert opinions change over time.
So if you could find a group of people willing to do regular interviews with you on a specific topic, I think it might be valuable. Then continue to present the group quarterly or semi-annually or whatever seems to be appropriate for the topic. You should continue to do profiles on executives and managers of blue-chip companies in Japan as a way of getting people to better understand and learn about a particular company. Let them learn about companies through the voice of the chairman or president. People usually find these kinds of profiles interesting.
