Since 2003 I have been visiting Chiba regularly where the greatest number of my friends live - it is easily accessible from Narita Airport - it has many cultural and historical locations, many very good restaurants.
It is also a centre hub to anyone exploring the Chiba Prefecture, all within hours, such as Sawara, Sakura City, Bogo Village, Museums and others.
Good to self drive around for sightseeing and shopping. Many many nice hotels all around Chiba. The south and east coast must go and stay in trip.
Get out and travel to different areas. Japan is pretty much connected everywhere, so make the most of your trip to Chiba.
