>>1514157>Japanese think lesser of other Asian countries
Thailand, Singapore, Taiwan, South Korea and increasingly Indonesia and Malaysia are popular travel destinations for the Japanese, who hype the culture and traditions of those countries about as much as a Goa backpacker.
Even the Japanese have plenty of people who go to India to "find themselves".
The Japanese are, if anything, possessed of an inferiority complex about their own country, as you'd know if you'd actually been out there and talked to a few.
The occupation era and the US' long-standing status as both the greatest importer of Japanese products and the tacit watchdog with military bases all over the country has instilled a kind of silent conviction that Japan is "only an island country", and combined with the aftermath of the Bubble still not being over, going overseas is seen as extravagant, almost preposterous.
There's also a lot of stuff about how that worn-down national identity and face culture affect actual English-speaking ability, which in the end means that Japanese tourists default to Hawaii because it has a Japanese-speaking infrastructure and plenty of Japanese people lived there even before the war. There's also a rather different culture and a lot of sun, sand and nature that you have to go to Okinawa to see in Japan.
And as >>1514008
says, not all Japanese keep to safe vacations and those who don't often do crazy shit like trekking Africa thin with a single camel or luggage car.
The Japanese aren't "serious" or "conformist" as much as they just place a very strict dividing line between "work" and "play". No one's going to put in a huge amount of work for an adventure vacation unless they're really passionate about traveling, in which case they emphatically will, because one is relaxation and the other is your ambition.
