A new study found that lost among the swell of inbound tourism, overtourism and the perpetually weakening yen is a strong rip current pulling Japanese travelers into the uncharted waters of solo travel.

According to market research provider Euromonitor International, 19.2% of Japanese tourists prefer to travel alone — more than any of the 39 countries surveyed. Japan not only sits far above the average global preference for solo travel (just 7.2%), but domestic travelers also lean toward individual sojourns much more than those with siblings (8.8%) or parents (6.6%).
