Well, its not realling tracking as tracking but as long you have proof of send the Japanese post office will  look at it. 

but my registed parcels take usually longer than my non-registed.

Ahh, okay, thank you! 
Normally airmail takes 11-14 days including weekends to get here, so I am really nervous about that one. It's been forever, but another parcel that was send later already arrived after one week. ;___; 

100% contact the person who send it.

Japanese post always helps out to find something back.

My main interests are J-music (okay, mostly VK), extreme metal and gothy/post-punky stuff. For the first I use MH, for the others I use websites like Cvltnation, NoCleanSinging and random music related groups I'm a member of on Facebook.

Anything that doesn't fall into these categories I just stumble upon, by accident.  

I'll search for a song I like on YouTube then click on the playlist suggested by the song. Or I'll go on Spotify and listen to an artist's radio, which is the same as shuffling through similar music by other artists. Sometimes I'll look through download blogs or just the news section here. 

This very forum, since I avoid youtube.
Either the news, reviews or DL sections do it for me. Sometimes recommendations from a friend.
