The Lie: Some Japanese (especially children) are so unused to foreigners, they will want to touch your hair.
The Truth: This has never happened to me or anyone I know (except the person who told this to me). I can only guess this is something that happens only in the deep rural areas, or happened in the past.
The Lie: Everyone travels during Golden Week.
The Truth: Not even close. A lot of Japanese have to work during Golden Week, and those who don’t either don’t want to deal with tourist crowds and inflated prices, or would rather stay home and relax.
The Lie: The trains are always on time.
The Truth: Absolutely not. Despite the reliability of trains here, delays occur daily.
