moboff YOTSUYA

When looking at a map of Tokyo, Yotsuya is located smack dab in the geographic center of the city. While not known as one of the major business districts, the Yotsuya/Kojimachi area is full of medium-sized office buildings, universities, and parks along the old outer moat of the Imperial Palace.
The building that houses moboff YOTSUYA was built 30 years ago (earthquake resistance construction completed 2 years ago) and is not much to look at from the outside. However, it’s located right on Shinjuku Street across from Sophia University and the upper floor feature verandas. We entirely renovated two floor with a mix of coworking spaces & private offices. 4F opened 01/2010, 5F opened 07/2010. Designed by Ben Nagaoka from Point.
