Shenmue/Capsule Toys

Outside several stores in Shenmue you'll find small gashopon machines - Capsule Toy dispensers that give you a little plastic toy or figure in exchange for ¥100. They don't serve much purpose in the grand scheme of the game, but there's some pretty cool trinkets to be had.

There are two machines in Sakuragaoka - a green "SEGA" one and a yellow "Virtua Fighter" one.

Harbor Lounge
There are three Capsule machines in the Harbor Lounge, one of which will give you some fairly intricate (but possibly boring) harbor-area vehicles to collect. The harbor models are some of my favourites though, because they give you a chance to examine the in-game models close-up.
