The museum is located just across the street Little Tokyo and very close to the Gold Line station, so it is very easy to access without having to drive. However, if you have to drive there is parking all around the area. I paid $8 for a spot across the street. The museum itself is very new and modern. The first floor is made up of a few temporary exhibitions and the second floor is made up of all the main exhibitions.
As you walk upstairs, you begin a journey back in time...a very sad portion of American history that should not be forgotten. The main portion of this museum is comprised of artifacts and stories from the WWII Concentration campus the US placed hundreds of thousands of Japanese Americans in. What really made this museum stand out to me are the docents. The docent I was privileged with talk to me for over an hour telling stories about his occupation and daily life in the concentration camps.
Admission is only $9 (Students $5 w/ID). On Thursdays between 5pm and 8pm it'[s free to get in. The 3rd Thursday of every month is free all day. They are closed on Mondays.
If you happen to be in the Little Tokyo area of downtown LA, this is a great museum to check out.
