To get to Shinjuku Mitsui Building, go from the Chuo-dori (Central Street) in Shinjuku West Exit, past the Cocoon Tower and Shinjuku Center Building, and you'll find it in front of the Keio Plaza Hotel on the side of the Chuo-dori Higashi intersection.
Alternatively, if you go towards the Tokyo Metropolitan Government Building through the West Exit underground mall, and pass the Shinjuku Center Building and the Kogakuin University, you'll arrive at the ground entrance to the Mitsui Building after walking a little while.
And, there is a seating area called "55 Hiroba" on the B1F of the Shinjuku Mitsui Building.



There are more than 20 sets of tables that can accommodate 4 people.
This wide rest area, which can be called an oasis in the city, has benches for one person and places to sit in addition to table seats.
It's called "55 Hiroba," but I think few people know about it.
What is the origin of 55? Is it "Go Go"??
The answer was in the Shinjuku Mitsui Building.
If you count from the bottom of the mirror-like building windows that reflect the surrounding scenery, it has 1, 2... 55 floors!
That's what it was.
This rest area has a chic design with brickwork, and has a three-dimensional effect with a spiral staircase and connecting passages.
And, if you look towards the Chuo-dori side, there are water flow objects and small waterfalls.


As if shutting out the hustle and bustle of Shinjuku, the sound of the waterfall flows pleasantly.
You can feel the negative ions (old), and it's recommended to take a break here.
It's truly an oasis in the city!
In this spacious and open rest area, families with children, girls' gatherings, couples, office ladies, and salarymen were using it as a place of relaxation, regardless of age or gender.
It's a rest spot to remember when you want to take a break in the Shinjuku West Exit area!
Also, it's the best place to eat lunchboxes in Shinjuku.
That's because the lineup of trash cans is great!

It might be as good as a service area on a highway, or even better than a small parking area.
Also, 55 Hiroba is used for events such as flea markets and concerts.
When you get tired of the crowds in Shinjuku, why not take a relaxing break under the zelkova trees?
It might be good for Nomad/Remote work or desk work.
Also, the "table seats and standing desks with free Wi-Fi" nearby are highly recommended, so please stop by as well.
If you are looking for a similar rest spot with a plaza in Shinjuku, try this too!
So, how about using it as a rest area where you can sit down around Shinjuku?
