I'm going to list them from who I discovered and liked first to my most recent favourites.
1. Ebihara Yuri 蛯原友里 She's such a classic beauty! Who doesn't know her as she was and I believe she still is one of Japan's top models. Her popularity goes back way in early 2000. She was the cover face model for the Japanese fashion magazine CanCam, which was the magazine that got me to know about her. I used to read CanCam a lot when I was in my early 20's and because she was always featured in it and I became immediately attached to her as she is absolutely gorgeous with beautiful features and flawless radiant skin. She is what I define as an elegant and beautiful model as she gives off a very elegance kind of beauty aura. Aside from modeling she also does some acting as well and I have seen her on TV for commercials and variety shows before.

2. Nozomi Sasaki 佐々木 希 I know her since way back when she used to be an exclusive model for the Japanese fashion magazine PINKY, which is now discontinued. She used to be the face cover model of that Japanese fashion magazine and I used to adore and love her sooooo much because I thought she was the cutest model ever! I would used to read every issue of PINKY just for her. She was also extremely popular during the 2008-2010 time but nowadays I don't really know what she's really up to anymore. I know she owns a fashion boutique business for dog clothes and she also has her own wedding dress design campaign or some kind of fashion business along those lines. I don't see her as often in Japanese variety shows much now compared to before during her prime time when she was all over everywhere in Japan. Especially during the time when she did a commercial for Lotte Fit's bubble gum and she did this super cute dance in the video that it literally became an instant hit in Japan where many people posted videos on youtube doing the same dance. I remember watching the commercial on repeat so many times! Since then the last time I ever saw her on TV was in the fashion TV drama FIRST CLASS. However, I still think she was and is one of the cutest Japanese models up to this date.
3. Lena Fujii 藤井リナ OH LENA! She was once crowned the "sweet Japanese princess" for her super cutesy and sweet looks. She was a regular top print model for the Japanese fashion magazine ViVi. She's half Japanese and half European. Her two moles at the side of her mouth is one of her charming appealing points as many Japanese people found her cute with it. I personally found them rather distracting at first but with time I grew to like them on her and think they're kind of cute. Lena was a really popular model back then until she graduated from ViVi magazine. I kind of miss seeing her in there because she used to be the model in the magazine. She totally owned that magazine. She can be cute, elegant, cool, sexy and super girly. She was a versatile model that I admired and liked a lot but ever since she graduated from ViVi, I haven't been following her and her whereabouts anymore. I'm not quite sure what kind of jobs she does now or where she is even at now. But I suppose she is still working as a model in Japan. She also used to be all over tumblr with many reblogs everywhere. The good old days when she used to be a prime model.
4. Tsubasa Masuwaka 益若つばさ OH TSUBASA! Who didn't love her back then when she used to be the QUEEN of gyaru Japanese models in Japan?! She was the one who made circle lenses a huge hit back in 2008/2009. Everybody was going crazy over her own circle lenses brand that she launched and those super cute Candy Doll makeup products she made as well that every girl couldn't resist not buying (myself included) lol. And not to mention how she rocked the blonde hair dolly eye makeup look soooooo well. And all those awesome hair wigs she wore too. She was like the CUTEST doll alive with her dolly make makeup. She was also the one who made the "usagi" bunny ear headbands a huge fashion trend as well and now people can't seem to stop wearing them. And she used to be super popular on tumblr as I remember seeing her everywhere on almost every fashion blog. But somehow down the road, her popularity also started to fade after 2012 or so and I have also kind of stopped following her since then.
