If I were to go to Japan (part 1)

For when I (finally) go to Japan. One is allowed to dream and plan, right?

Here are 2 rules:

1. I have a budget. This means nothing fancy, except if it's a must-see, must-try kind of thing. And in my opinion, the only things that are must-see or must-try, are things that locals participate in.
2. I want to experience local life as much as possible. I'm not really into expensive touristy stuff, though I do enjoy it sometimes. I'd just prefer to experience how locals live, which explains last  line of point 1 above.

Here goes...

I will fly to Osaka first - Kansai International Airport. I reckon Osaka is still a city area but with more greenery and open spaces. I hope. I'm a person who needs greenery and open spaces, that's why I realize I can't stay in HK for long.
Also because Osaka's got a major airport, so flying in will be easier. No other specific reason.

If you've got a suggestion as to where I should fly in besides Osaka, leave a comment!

There're probably a few places I want to try staying in, so I won't just be in one place. Planning to do a homestay, booking a place through Airbnb (@airbnb). This way, I can actually see how a local lives as well as meet somebody new. That costs about $45/night. I could try a hostel, but I'm not so keen on the idea as of now.

Another place I want to stay at is a capsule hotel. Maybe one like Capsule Hotel Asahiplaza Shinsaibashi for about $46/night. I hope those capsules are safe.
