Can she sells signed copies? I'm not sure if it's a thing or people care in Japan about it, but this is one the things that has been moving copies in UK and US, besides bundles. Vinyls are also selling good numbers, but again, not sure how this would be received by the japanese audience. Both are more collectibles to be honest.
Also, besides Go To The Top she never had tour bundles anymore. That moved a lot of copies for the single, it even managed to go number 1.

Just now I noticed that they have footage from her first concert ever, in the interlude for MY NAME IS... Tour (walk and Go Together are shown). I'm really shocked that this was recorded, even tho in a VHS for what is looks like. Is it too crazy to want the whole thing even if it is just one angle?
In 2002 she did two dates for a concert called プレミアムワンマンライブ (Premium One-man Live)

This was the setlist:
