too と very の違いは何です?

Here is one that often confuses Japanese students. What is the difference between too and very? This is one is very easy.

When the temperature outside is 34 degrees, it is very hot.

(You can still go out.  I see many office workers dressed in suits. Be sure to carry a bottle of water.)

When the thermometer reaches 50 degrees, it is too hot.
(It has passed a limit.  It might be dangerous to go out.)

Here is another example.
A 3LDK house in Hamadayama costs 80,000,000 yen. That is very expensive (But if you work hard, save a large part of your earnings and invest prudently in the stock market, you have a good chance of owning one.)

Some houses in the Pacific Heights area in San Francisco are in the neighborhood of 1,000,000,000 Yen. That is too expensive. (It is impossible for an average office worker to buy such a house.  It's over the limit for 99.7% of buyers.)

For emphasis, intonate too. For example, that is tooooooooo expensive.
