Thought some people here might be interested to know that old episodes from Popjam are being aired on Sundays at 10:00 p.m. on the Kayou Pops Channel. It's a cable channel in Japan like akin to VH1 Classics. They started reairing episodes of Popjam in May and so far have done three episodes from the 90s. Not sure how many they are planning to air. Haven't found a great source for these yet to download, but I did manage to get an HD-rip of one of the episodes. I contacted a capper at JPOPSUKI to see if they would be willing to record and post these. If anyone else knows any cappers, please try asking them to record these gems.
No episodes with Ayu yet.
