Japan’s tourism authorities are baffled. The number of overseas tourists is increasing to new all-time highs, but that rise is not necessarily reflected in the number of foreign customers staying at hotels or Japanese-style ryokan inns.
So where are they all going?
One theory is that they are spending nights in airport lobbies, express night buses, love hotels, 24-hour public bath houses, Internet cafes, or other venues not included when tourism authorities tally up the count.
"Japanese hotels are outrageously expensive even though their rooms are small," said Amaury Lemal, a French toy designer, who decided to stay overnight in the lobby of Narita Airport.
In the airport lobby, 10 or so Western tourists were also catching up on their sleep, covering their faces with jackets or towels.
That is also the case at Kansai International Airport. At an all-hours lounge, many tourists stay up until morning. The airport offers blankets for free for such travelers.
