>From your workstation, first show us what the IP addresses resolve to like so:

$ host japanese-usage-dictionary.googlecode.com
japanese-usage-dictionary.googlecode.com is an alias for
googlecode.l.googleusercontent.com.
googlecode.l.googleusercontent.com has address 64.233.178.82
googlecode.l.googleusercontent.com has IPv6 address 2607:f8b0:4003:c0a::52

Next, run this command so that we can see the network connections
being attempted (you may need to install 'strace' first):

$ strace -e trace=network svn checkout
http://japanese-usage-dictionary.googlecode.com/svn/trunk/ 2>&1 | grep
^connect

It looks like you are having a network connection problem, so this
will show everyone what IPs and connections are failing for your SVN
checkout. I suspect that you have some sort of network block, or an
IPv6 routing problem etc. As just an example, I do not have IPv6
capability from home (ISP does not support) so all connections fail
for IPv6, but IPv4 is working find and the SVN checkout is working.

$ strace -e trace=network svn checkout

What you're looking for is one of the IPv4 address connection lines
*not* = 0 (success), but instead show it cannot connect. Then once
it's identified, use a tool like curl or netcat (or even telnet) to
test that IP outside of SVN to confirm.
