In graying Japan, where a rising number of people are living alone, being single doesn't necessarily equate to being lonely.

More than 70 percent of single people in their 40s and above not only reject the idea of eventually tying the knot but claim they are satisfied with solitude and that they're prepared for the autumn of life alone, according to findings by end-of-life consultancy firm Kamakura Shinsho Ltd.

The company believes the outcome of an online survey in May of single people — including divorcees and widowers — in their 40s or older nationwide, reflects the rise of solo living and associated concerns about dying alone.
