One of the most famous super star of Japan is Hello Kitty by Sanrio.
She always acts as a liaison between foreign countries and Japan. She is playing the biggest role as an ambassador of Kawaii Culture.
I visited Sanrio Café in Ikebukuro. There are many Kawaii characters of Sanrio, Hello Kitty, My Melody, Cinnamoroll, Pom Pom Purin, Kuromi, etc.

To say nothing of Ikebukuro, is also famous for Otome 乙女road where has lot of girl’s otakuオタク(nerd) shop paradise. There are many stores of amime goods in Otome road. Especially Fujyoshi腐女子 (girls who really love to B.L.(boy loves boy) comics and animes)) must be fascinated by these flamboyant world!
On the contrary to, Akihabara is the paradise of otaku guys or geeks 🙂 who love lolita girls and cute school girls’ animes. The area has a concentration of computers, video games, anime goods, retro games, dvds, home appliance stores in Akihabara.
Oh no, I am getting off the track. Ok, I am back to the main topic, sanrio café.
Sanrio stores can be found everywhere in Japan. But Sanrio cafés are only located in Ikebukuro (Tokyo wards) and Kamakura (Kanagawa prefecture).
I ordered Kuromi soda(iced coffee with black sesame taste icecream)
And Kuromi pancake!(chocolate pancake) @Sanrio Cafe. Cause I am a big fun of Kuromi.

Kuromi Soda & Kuromi Pancake
Kuromi has gothloli(abbreviation of gothic lolita) look with black costume and wearing heavy make up(look like the rock band Kiss!).
According to Hello Kitty Wiki, https://hellokitty.fandom.com/wiki/Kuromi
Kuromi 
My Melody
Kuromi (クロミ, Kuromi) is My Melody‘s rival, who is a white rabbit or imp-like creature wearing a black jester’s hat with a pink skull on the front and a black devil’s tail. The skull’s facial expression changes to match Kuromi’s mood. Fittingly, her birthday is Halloween (October 31st). Her name translates from Japanese to English as “black beauty”.
Kuromi’s appearance is also similar to those of cartoon characters from the 1990s such as Pichu from Pokémon. Kuromi has become a popular character for the punk, scene, and goth crowds due to her appearance.
If Hello Kitty and My Melody were angels, Kuromi would be a sweet little demon. She has just irresistible charms for gothic lolita-lovers. Don’t you think she is intriguing anything against My Melody above, do you?
Let’s enjoy the sub-culture paradise of Ikebukuro and Sanrio café!
