 If you liked Doraemon (1979) |  ...then you might like Bonobono (TV 2016) |
The Anime are very simmilar as there is a group of friends that do stuff together, Doraemon is more based on inventions and things you wouldn't normaly see while Bonobono is based on friends having fun. They are both pretty funny. Both are recommended if you just want to watch something relaxing.
