I had worked at Akihabara for 7 years and I know lots about local food place in Akihabara. And, yes, I have been to many RAMEN places but this one always has the longest waiting hours in Akiba as RAMEN place.
OMG, I arrived here at 12:00 and about 30 people were waiting including the ones inside.
Notice, 99% of the customer is male…. I guess those are the Ramen enthusiasts…!! Though it seemed too many people, the rotation rate is high because most of the customer concentrated to “eating” and “tasting” this most popular ramen in Akihabara. Also, they don’t allowed to any groups and couple to sit next to each other when busy time. So…, I could not to enjoy girls talk with my friend…we were not allowed to sit next to each other….ohhhhh…
Signage “AOSHIMA RAMEN”
Menu, You should order “CHASYU-MEN” it is the best according everybody in internet…haha
We waited about 40 min…..
Inside looks like this, totally for “RAMEN” only….no chit chat is allowed!
Among male Ramen enthuisiasts, we looked like we came from the different planet…hahaha.. No body was chit-chatting…..
Here comes the RAMEN!!!!
Yes It was delicious!!!! It is in my Ramen list but for me, another shop “TSUMUGI” that I already introduced as Local Food Akihabara #3 (Ramen Tsumugi) stays No 1 and this comes No 2!! You should definately visit both “AOSHIMA” and “TSUMUGI”.

Forgot to mention where
Address: 3-2-1, Kanda-sakumacho, Chiyodaku, Tokyo MAP
〒101-0025 東京都千代田区神田佐久間町3-20-1 大杉ビル1F
Direction from Akihabara Station: Go to SYOWA DORI exit. You see Yodobashi Camera on your left and a big cross walk just in front of you. Pass that cross walk. Then, you see the RAMEN shop straight to your face. and just take the small road next to it (don’t go left side, go to right side of the RAMEN shop). This goes straight ahead below the train (train goes your above) and you see Seven Eleven on your left and Karaoke shop on your right. Keep walking this road about 200m or so, you see a small park. There, you turn right. And you’ll see the “AOSHIMA RAMEN” at 1 second!
