What facts about Japan do foreigners not believe until they come to Japan?

 I was in Tokyo for almost 1 month in December 2014. I was abroad for the first time in my life and indeed, it was full of surprises. I share few:

• In my office there's a refreshment area with a very small convenience stall. The stall had packed food, chocolates, candies and a Box. Yes, the box was the store keeper. People just take whatever they want and put the money in the box. Simple. Sounds unreal, at least to Indians. Similarly, may it be a supermarket or a small store, everything is out in open, without any tagging. Actually, for a Japanese person stealing is unreal. Visit Japan and get amazed by their honesty.

• We used to travel by Tokyo Metro and used to change from Yurakucho line to Ginza line. The connecting stations were around 600 m apart, that we used cover by walking through an underground passage, that had many turns. The amazing thing was, throughout the way, there were old men appointed just to tell the right way to the commuters and beg their pardon for the inconvenience. It may be hard to visualize but very touching to witness. It's just a small token of their hospitality.

• We were at Chinatown, Yokohama. There was a narrow lane (Sufficiently broad from Indian perspective). There were no cars on that lane. We thought, It's a no driving zone. After some time we saw 4 cars back to back that were drifting very-very slowly and right in the front of the very first car, we saw an elderly couple walking right in the middle of that narrow lane. When I asked my friend about this scene, he told me that Japanese people consider blowing Horn as very rude. Even in my 20 days of stay, I don't remember any horn sound.
• Delhi Metro is a replica of Tokyo Metro, but one major difference. Tokyo metro is extremely quiet irrespective of the crowd. Actually, nobody even looks up. Sorry Housing.com. #BadPJ

• Petrol Pump, Gas Station, Fuel Station, these words are hardly used there. I had to do the complete animation of a car, fuel, machine, to ask for one. BTW you won't find any attendant at such places. Just use the machine and fuel your vehicle.

• Queues: Whether it's Metro, Mall, Signals, Escalators or just nowhere, you'll find queues. Maintaining queue is in their genes. And there also, they never look up.

• Keep Left: Japan is fast paced, everybody is in a hurry. So to accommodate everyone, people stand only on the left side of the escalator and give way to the people in hurry. They don't have to enforce this, it happens naturally.

• If it doesn't happen in Japan, It doesn't exist. Yes it is an alien land. Japanese people don't use English, actually they don't understand, in the very first place. There are no English channels on TV, they don't know Cricket, they don't know Diwali, don't know Eid. Japan is a different world all together.
• Don't get dishearten, that "पधारो म्हारे देस" (Welcome to my country) feeling is everywhere. Here are some pics to contradict the previous point, and reestablish Japan as a must-visit place even for Indians:

1. Hospitality: Me doing radio exercise with Japanese colleagues.

1. Hospitality: Me sharing lunchbox with Japanese friends.

1. Hospitality: Welcome party by my Japanese mentors.

1. Helpful Strangers: One stranger helped me in finding Daiso (100 Yen shop) at Higashi-Ikebukoro station, leaving her trip in between.
2. And don't worry, Indian things are available. Here are few pics:

• Krishna Temple

• There are lot of Indian restaurants, but don't expect Roti there. Yes! they only serve Naan. We always wondered why the Naans were so big and fluffy, before we came to know that all of them contained Egg! I'm a pure-veg Brahmin. Poor me! Soon I found a costly Roti restaurant. :)

• Lassi

• Chai

• And finally, the Indian Style ;-)

• It was a summary of my overall experience but I am sure it adds something to this thread.
