For a while, Tokyo Joypolis had "JP GEAR" as a brand/label to promote items there. These are 2 foods with that branding as the main thing, and Sonic second. The red jar is labeled "Chocolates", and the green metal tin has "Cookies". The cookies look like shortbreads of some kind, likely in Sega or Sonic related shapes. That's all the bigger the photo is, so they're kind of anybody's guess, as well as reading any of the small text. You can see they are sealed with freshness stickers. The age of these is unclear.
