Do you like Slice-of-Life anime? Urawa no Usagi-chan and Morita-san wa Mukuchi are Slice-of-Life anime based on a high school girl's daily life. Both anime are also incredibly short (about 3 minutes per episode). They seem kind of similar on humor too.
"Wish Upon the Pleiades" / "Houkago no Pleiades" and "Urawa no Usagi-chan" are original series of shorts surrounding a group of young girls and were both made with the intent of advertising for something.
In this case, "Wish Upon the Pleiades" / "Houkago no Pleiades" advertised for the Japanese car manufacturer Subaru whilst "Urawa no Usagi-chan" advertised for the location of Urawa City in Saitama, Japan.
