Koban Visitor Center
If you hang out in a new place for 5 days without a map in hand, and don't know where you can get it, you would find the Koban Visitor Center a 'life buoy' like I did. They can give you maps of Los Angeles and Little Tokyo free of charge. Not just maps, stuck with ideas about where to go, eat and shop? Tons of addresses in and out of California with a brief introduction for you to consider. You even find coupons for reduced admission fee to museums. Bus routes and schedules are another thing you want to know to plan your trip. Don't worry! You can find in Koban Visitor Center too.
More questions? Don't hesitate to ask Tomo. He is an extremely helpful (and witty) resource person for you to ask whatever question you might have concerning your trip and stay in the Little Tokyo. Wow, I forgot to take his picture so you will know who he is.
