Naruto is not G rated, period. Just because kids like it, it doesn't means is suited for them.
If I would have time and mood I could find more, but here are what pops out from my mind:
Anyamal Tantei Kuruminzoo (anime) Aired in 2009-2010 with 52 episodes (23 mins), and wasn't that noticed exactly
for the fact that it was aimed for the youngest age category. The 3 Mikogami sisters find the research of their
grandfather and are able to turn into animals. In their animal form they utilize their abilities to solve some
"detective cases" which are usally very simple and funny.
Aria (anime/manga) - Aired 2005-2008 with 3 seasons, Aria, Aria Narural and Aria Originations. We all love Aria and we
all know that it is suitable for all ages, how comes nobody mentioned yet?
Hidamari Sketch - Aired since 2007, in already 4 seasons (Hidamari Sketch, Hidamari Sketch x365, Hidamari Sketch
Hoshimitsu, Hidamari Sketch Honeycomb) and countless OVA's and specials. It's long career exactly shows show
well liked In Japan this show is. Four girls live in a apartment building named the Hidamari Apartments, near the art
school where they are students. Showing their everydays life and worries, it's my no.1 recommedation for a all-ages
suitable show. Also one of the few which is published as official manga in english under the name "Sunshine
Sketch"
Panyo Panyo Di Gi Charat (anime) Aired back in 2002-2003 with 48 episodes (arround 6 mins), but it was pretty common in
USA on DVD so guess in second-hand can be even purchased for a few bucks. Shows the life of Princes Dejiko on her home
planet, and unlike the previous Di Gi Charat series which had a rather weird humour, this was transformed to a suitable
show for children. Please note that this show is licensed in USA.
Pita-Ten (anime/manga) - Aired in 2002 with 26 episodes (24 mins) Please avoid the manga itself as long it has a much
darker tone. But the anime itself is cute and hilarious. Our main hero gets a clumsy angel as his neighbor and his
common life turns now heads up.
Sketchbook ~full color'S~ - Aired in 2007 with 12 episodes. Sora is a quiet and slightly airheaded girl who joins
the art club in her school, which has a great variety of members. Interesting is her innocent and simple minded view of
her experience in the club. The last episode is one of the nicest in the history of anime as she draws a picure with all
characters who she met.
Magical Meow Meow Taruto (anime) - a pretty old piece from 2001, which shows relationship of petite cat girls and
humans. Zero action, but lovely.
Moyashimon and Moyashimon Returns (anime/manga) - Aired in 2007 and 2012 respectively. Our main heroes manage to get
into a university - but a agricultural one! Is already weird when the director gives his welcoming speech from a top of
a tractor, and even more weird that our hero can see bacterias with his eye... Except the hilarious comedy you can also
learn about fermenting or how various foods/drinks are produced, so is really educative as well.
Nanatsuiro Drops (anime) - Known also as Seven Colored Drops. A anime slightly similar to Cardcaptor Sakura but much
newer and with a deeper guy-girl relationship element.
Tamako Market (anime) - Aired in 2013 with 13 episodes. Our heroes are children of shop owners in the market district.
One day a talking bird from a foreign country appears who is searching a suitable bride for the prince of his country.
Interesting also by the fact that it has the same character design as K-On.
Tamayura: Hitotose and Tamayura: More Agressive (anime/manga) - Aired in 2011 and 2013 respectively with 12 episodes
each. A high school girl moves into the home town of her mother after the death of her father. She enjoys photography
and quickly makes a bunch of friends. Heartwarming stories with 1st class music. In the second season, she tries to make
a photography club in her school. But as long she has a clumsy nature, her teacher recommends her "being more
agressive" which usually ends in some hilarious way.
Non Non Biyori (anime/manga) Aired in 2013 with 12 episodes. The city girl Hotaru moves to the countryside due her
fathers job. The series makes a parody from the slow village life, but in a very cute way. The characters are lovely
with great, but not crude jokes.
Gingitsune (anime) - This anime ended just a month ago with 12 episodes. The main girl comes from a priest family and as
a successor she has the ability to see the guardian deities of the shrine, in our case a silver fox. You can also look
behind the scenes of japanese traditions and celebrations.
Kiniro Mosaic (anime/manga) - Aired in 2013 with 12 episodes. Shinobu-chan really loves western culture and her dream
comes true when she is able to homestay in England for a year. But now when she is older, the situation turns arround
and her english friend Alice transfers as exchange student right into her class.
