Found this extremely interesting article on japan-talk.com. I’m taking a part of the article which I share sentiments with, of which I would add some of my personal comments below in italics. Enjoy!
At some point every foreign resident of Japan starts to wonder — have I been here too long? Here are the top signs you’ve been in Japan so long that you’re basically Japanese:
1. When you’re outside Japan you still call non-Japanese gaijin.
Well I don’t call people “gaijin” generally for it’s basically rude, since “gaijin” originally means “outsider/ alien” instead of the usually intended “foreigner”. But yes, we do love to make fun of our “alien”-selves, be it in Japan or outside. More for a “gaijin” who cannot speak Japanese.
2. You’ve continued to work through a shindo (震度) 3 earthquake without slowing down or bothering to mention it.
Having gone through the biggest earthquake Japan has ever experienced, shindo 3 is literally “no-kick”, or “a piece of cake”.
3. You’re giving the peace sign in most of your Facebook photos.
I’m embarrassed to say that I have that peace sign even before coming to Japan…(^^ゞ
7. Most of your vacations are geared towards taking hot baths.
Oh yes… I’m actually going for one after writing this article. Onsen ftw!
10. You bow when you’re on the phone.
This is so true. I bow most of the time in the presence of people (like in a train), or without (like on a phone).
11. You’ve had a conversation with a vending machine.
I learnt how to talk to inanimate objects, having being taught the teachings of Shintoism, that gods dwell in all things.
12. You regularly use a manga cafe as a hotel.
Either that, or a capsule hotel. Those are the cheapest forms of accommodations. Oh youth hostels? Sorry that’s for “gaijins” (Refer to number 1.)
13. When your train is one minute late you start to think it’s your fault (maybe you have the wrong information).
When my train is 1 minute late, I start looking at my watch. When my train is more than 3 minutes late, I contemplate asking the station staff if there is an accident.
14. You don’t know the English names for most types of fish.
Indeed, Japanese cuisines contain so many fish types that I know more fish names in Japanese than in English or Chinese.
15. You’re curious about people’s blood type.
I understand this point, but I’m not that crazy for blood types yet. I have the tendency to ask for their shusshinchi (birth place), and try connecting it to their character/ names etc.
19. You’re starting to believe that romanji is English.
Yes, in fact, some times when talking to a non-English-speaking foreigner who speaks Japanese, it’s easy to talk in romaji. It creates a lingua franca between “gaijins”.
24. You’ve become extremely nostalgic about sakura (cherry blossoms).
Not just cherry blossoms, but I become very season-oriented. Everything is measured in terms of seasons- cherry blossom season, rainy season, red-leaves season etc.
33. You say heeeeey a lot.
Yeah… it’s the typical “surprise” reaction to whatever people say to you. A typical surprise reaction, ironically, is accompanied by a poker face.
39. When you use a taxi in your home country — you wait for the door to open automatically.
Oh yes the taxi doors in Japan are just so convenient.
40. You have accidentally apologized in Japanese in your home country.
If you tend to do the above and below, number 40 is a given.
41. You don’t feel Shibuya is all that crowded.
Nah.. Shibuya is not crowded.
55. You don’t mind when every channel on television is talking about food.
Either about food, travelling, or dirty jokes/ gravure idols/ weird pornographic jokes.
56. You get the urge to yell sumimasen at restaurants in your home country.
That’s the only way to get the waiters’ attention, no?
58. You’re starting to doubt your English pronunciation of Rs and Ls.
YES. What I first thought was just stupid, is actually coming true for me!
62. You own more than 8 umbrellas.
Japan is one of the safest country in the world. No one steals, except for umbrellas and bicycles. Also, Japanese umbrellas are usually strong, but usually give way in strong winds, and are usually gotten rid of on streets.
65. You’re starting to add -san to the names of other gaijin.
Oh yes… we must respect other “gaijins” too.
66. You are starting to think natto tastes good.
I’m still trying to convince myself………. Give me some more time.
87. You no longer get lost in Shinjuku Station.
Interestingly true, although that does not mean I’m getting better at my directions…
88. You don’t hesitate when you put 10,000 yen into a train ticket vending machine.
Come to think of it…. 10,000 yen is a hell lot of money!
