Japanese is rated as either the #1 or #2 hardest language for a native English speaker to learn (and the reverse is true which explains why you often run into people with little or no English there as opposed to in, say, Western Europe, where many people are practically natively fluent in English). People can and do learn Japanese, but it isn't something that one can easily learn in their spare time the way English speakers can learn French or Spanish.

I hear this frequently, but disagree strongly, at least regarding the spoken language. As a native English speaker who learned Japanese easily to the "could get by as a tourist" level with two semesters of college classes and minimal self study, I find French much harder (and I took 4 years during high school).

Unlike many southeastern Asiatic languages, Japanese doesn't have any sounds that the average English speaker doesn't already know how to make (possible exception in the 'l' sound, but, if you can roll your 'r's, it's the same tongue position). There are no articles, only two tenses, relatively normal conjugations (though adjective conjugation is odd relative to English), no declension, and sentence structure has strong hints of Latin. The simple-polite forms of verbs are sufficient for daily use. Pitch accent and ga vs. wa are hard to pick up without immersion, but neither are necessary to be understood.

The written language is a different story. Lots of memorization. The hiragana and katakana come quickly, but there are a lot of kanji. Probably not needed for tourists (particularly in the day of image translation on phones), but still a factor. Arguably still easier than Mandarin in that regard, though.

Additionally, there are an overabundance of resources for Japanese learners. The economic potential of American occupation under MacArthur and the subsequent boom years, the enduring popularity of Zen Buddhism, and the rise of anime's popularity in the West have likely all contributed to Japanese being one of the best-supported Asiatic languages in academia and self-study courses. Its support in the USA is exceeded (in my estimation) only by Mandarin due to the large immigrant population and ongoing trends in trade.

In short, I'm sure the number of native English speakers who can "get by" in Tokyo eclipses the total number of native English speakers with basic Lao, Thai, Khmer, Vietnamese, and probably even Mandarin skills.

Just one datum.

Written Japanese is a difficult language for native Japanese people. One would be in high school before one has learned enough Kanji to read a typical daily newspaper.
