Meet Mr. Yukawa:
It is a possible to meet very famous (in Japan at least) senior executive officer of SEGA Yukawa-san in Shenmue as a hidden event.

To see him you must get the 'happi' and 'suit' figures of him at Abe Store in Sakuragaoka's raffle . The best way to get to see him is if you have only one of eatch statue. It is reccomend you save as soon as you get one, and then keep trying to be sure you don't get the same one twice.

When you have them go to Takara Sushi on the 9th of any month after 8pm. He will be sitting in the bar eating. In the Japanese version of the game, Ryo used to talk to him, afterwards he would run away. If you want to see him again go outside and back in again. You can do this as many time as you like between 8 and 9. On the international versions, Mr. Yukawa is not interactable.

Mr. Yukawa was the main subject of the Japanese playable demo: "What's Shenmue".

Listen to cassettes without using batteries:
Go to Tom's Hotdog van in either Dobuita or the Harbour and look at the cassette player. You will then be able to play your music collection without using batteries.

Infinite Work Days/Yen:
On the third day of work when you take crates to warehouse #3, you're supposed to go check out warehouse #17 after work. Well, if you never check out the warehouse, you will keep on repeating the same work day until you do to advance in the story. This trick is good for getting lots of yen.
