How do I fight japan man in mega man battle network 3

to fight japanman you have too have a gigachip. get the gigachip from the undernet.first jakcin the lion spa thing, then talk to the netdealler and he'l sell it to you for 2oo bugfrags Edit: YamatoMan (that's his real name, Nintendo of America be damned) is located in Secret Area 2, and is only available after Alpha is defeated. You will need one gigachip and the hammer from Undernet 7. To obtain a gigachip, jack into the gargoyle on HadesIsle, not the "lion spa thing," and go through the warp point to the bugfrag trader in Undernet 2. He will sell you one for 200 bugfrags.
