Address with No Postal Code

I have a 1995 address from a return address on an envelope and I want to make sure it is correct. Trying to check on a former exchange student post earthquake:

111111 Fukumitu
Nagara, Gifu
Japan

I guess the postal code is missing and I'm concerned it won't go through... I tried a few lookup services and it looks like the address should be:

111111 Nagarafukumitsu, Gifu-shi,
Gifu-ken
502-0817

Is this correct??

Bristow,

Assuming that you're just making up the "111111" part for anonymity, yes,
xxxxxx Nagarafukumitsu,
Gifu-shi, Gifu-ken 502-0817
exists.

Postal codes are no big deal. Letters will be delivered whether you write the code or not.

By the way, Gifu have not been accected by disasters for a very long time.

So would it be normal to have a 4 digit number? like XXXX?

Is it four digits like x-xx-x or something with dashes in it?

Nope, just a four digit number with no dashes. Her parents lived in a single family home, which I know is rare. She may as well.

I've just checked the numbering for Nagara fukumitsu on yahoo! map, and the numbering starts with 1 and goes right up to 2941, just like that, with no dashes, so that type of numbering must be normal in that area.
