When I travel next, I want to reach the point on the earth that is exactly opposite my home, how can I discover where that is?

The Google Earth application makes this really easy, no searching or math required. Just choose tools->ruler. Zoom in on your home and click to begin measuring. Zoom out and rotate the globe until the ruler starts spinning around the globe in circles. Zoom in on that spot and keep moving the ruler until you’re as close as you want to get, then note the coordinates.

Wolfram Alpha could help here as well.

For example, typing in antipode of London, UK shows a map with a point south of New Zealand.

Find a globe. Put your arms out front with the forefingers pointing in. You are now a human calliper. Bring the arms together to nip the globe such that the left finger touches home. The right finger is now on the target.

Rotating the globe might help, unless you’re a gymnast.

It’s very easy, and a quick google search for ‘antipode’ and ‘map’ will find sites that find it for you.

For example, Antipodes Map either detects your location, or you can enter one, and it’ll show you on a zoom-able map where your antipodal destination is.

Unfortunately as shown by the map above, only about 15% of land territory is antipodal to other land, and only a tiny fraction of Brazil is antipodal to Japan (in fact, to the islands of Okinawa and Amami). A rather larger amount of Brazil (but still a small fraction of the country as a whole) is antipodal to the Philippines and Indonesia, along with Brunei, parts of Malaysia and the South Korean island of Jeju. Without knowing your exact location I can’t be sure where it ends up. I’ll leave that last step up to you to investigate!

Another “Map Tunneler” site shows it quite nicely side by side. I can click and zoom in on New Zealand and the other window zooms in at the same time to show me northern Spain – the antipode.

Yes the lat/lon coordinates are your friend. Lets assume the following coordinates are yours:
S 9° 17′ 42″, W 51° 19′ 17″. You are 9 degrees south of the equator. Your antipode will be 9 degrees to the North. Just replace the S by the N and you have the latitude of your antipode (N 9° 17′ 42”).

You are 51° 19′ 17″ away from the Greenwich line. Which mean 51 degrees, 19 minutes and 17 seconds. 1 degree contains 60 minutes and 1 minute contains 60 seconds. To get the longitude of your antipode, you’ll need to do a bit more math. The antipode will be 51° 19′ 17″ away from the 180° longitude. To get the longitude which is relative to the Greenwich line, you need to subtract your longitude from the 180 line. It will become E (180-51)° (60-19)’ and (60-17)” 

180    0     0
 51   19    17

You don’t want to have negative minutes and seconds, so you borrow a degree and subsequently a minute:

179   59    60
 51   19    17
===============
128   40    43

It appears that the antipode of the center of Brazil is close to the Philippines.

There are a multitude of online calculators to identify your antipode just google search for them, but I prefer the pencil paper calculation due to its simplicity. Also using a calculator without explanation on how the location is derived feels like falling for tourist traps 😉

Use the Map Tunneling Tool. Unfortunately you won’t reach any islands in Japan unless you live close to the Uruguay border.
