There is a free tour bus for "Metrolink Nihonbashi / E Line". In Chuo-ku, there is another ward-operated "Edo Bus" 100 yen. Chuo-ku is very blessed with many free bus stops in Tokyo. You can easily enjoy sightseeing and shopping in the Nihonbashi, Tokyo Station, Kyobashi (Ginza / Yurakucho) and Ningyocho areas.
Nihonbashi Line
Nihonbashi E Line Yellow Bus
There are two routes, but the course (one-way) traveling around Tokyo Station, Nihonbashi and Kyobashi districts is every 10 to 15 minutes. The E course that travels around Tokyo Station, Nihonbashi, and Ningyocho is (one-way) every 22 minutes. There are five common stops: Tokyo Station Yaesu Exit, Subway Mitsukoshimae Station, Nihonbashi 1-chome, Nihonbashi 2-chome, Yaesu Underground Shopping Center. Weekdays 8:00-18:00 Saturdays, Sundays, and holidays 10:00-20:00
First of all, while comparing the Chuo-ku map with the route map (get the course table in the bus), I left two courses from Tokyo Station to check the location of the bus stop and went around. I wrote the location of the stop on the Chuo-ku map. (The stop on the road side is easy to understand, but the display on the building side is difficult to understand. Some stops may be changed due to construction work.)
When I knew the location of the bus stop, I got off and walked from one section until I could walk, and I repeatedly took the bus if I was tired. I couldn't find the bus stop that I should have confirmed from the bus.
Here are some places that are 
conveniently used at the stop. 
Tokyo Yaesu Exit-Tokyo Station is mainly used by those who use Tokyo Station. From Tokyo Station, walk along the Sotobori-dori St. in the direction of Nihonbashi. It was difficult to understand because it was far from Tokyo Station in front of the Iron and Steel Hall. Personally, I think the Yaesu subway street in front of the station is convenient. Underground Mitsukoshimae Station 1-chome Nihonbashi Muromachi - Kanda Station can also be reached. You can go to Hamacho 2-chome Meijiza-mae-Hamacho Park / Higashi Nihonbashi Station. It's in front of Suitengu-mae Subway-Royal Park Hotel, so you can walk to Ginza on Suitengu-Tokyo City Air Terminal Nihonbashi 2-chome Takashimaya Kyobashi 2-chome-Chuo-dori. If you walk as it is, you can also reach Yurakucho Station and Shimbashi Station. I go through Harumi-dori St. to Higashiginza, Tsukiji, Kachidokibashi, and walk to Tsukishima.
The bus stop of the Edo bus is also difficult to understand, so you can see it when you go around. If you are tired of walking, you can take a walk freely in Chuo-ku by repeating the bus.
It is also recommended to combine the metro rings with Edo buses. Since the Metroling does not run at the end of Chuo-ku, the Edo bus runs to the end of Chuo-ku.
The Edo bus is also divided into two courses. First of all, pay 100 yen, and the ward office (get the Edo bus MAP in the ward office book) is the departure / end point, so let's go around Ningyocho, Horidomecho, Higashinihombashi, Bakurocho, Nihonbashi courses. When you get off the bus at the ward office, if you get a transfer ticket, you can also go around the Tsukishima, Kachidoki, Harumi and Toyomi courses for 100 yen. However, if you get off once, it is only effective at the transfer station, so if you want to get on and off many times. 300 yen per day ticket is a great deal. Every 20 minutes. Weekdays 7: 00-18:40 Saturdays, Sundays, and holidays 18:40 (from ward office)
Here are some of my recommended courses. 
If you index "Free Tour Bus TOP" on your smartphone, it is convenient to tap Metrolink Nihonbashi to move the bus position in the operation status. The position of the bus is moving properly, so you can check when you will arrive at your stop.
Tokyo Station-Tokyo Yaesu Exit / Yaesu Underground Shopping Center (both courses are OK) Get off at Nihonbashi Muromachi 1-chome / Shin-Nihonbashi Station [Antenna Shop Nihonbashi Fukushimakan ⇒ Senbikiya ⇒ Mie Terrace ⇒ Bridge Niigata ⇒ Narakan Mahoroba ⇒ Shimanekan (currently closed) ⇒ Mitsukoshi Main Store ⇒ Nihonbashi Toyamakan ⇒ Yamanashi Prefectural Museum ⇒ Yamanashi Prefectural Museum ⇒ Nihonbashi "Shigakan" will open on October 29.
As a recommended resting place, the event on the 2nd floor of Mie Terrace is wonderful. On days when there is no event, Mie Prefecture information is displayed on the screen, so you can collect information on Mie Prefecture while taking a break. There are many events, flyers can be provided, and you can apply immediately.
I have been able to participate in many events so far. That's because I often take a break on Mie Terrace. Relaxing in a spacious space is the joy of wearing clothes.
"Fukutoku no Mori" can also enjoy greenery and flowers slowly on a sunny and warm day.
There are many people who enjoy lunchtime and tea time. I often read at restrooms.
The lounges on the 3rd and 4th floors of the Mitsukoshi Main Store have coffee makers. The chair is also spacious, so you can get tired when you want to take a break during shopping or strolling.
It was 3 o'clock when I was taking a break in the lounge in Mitsukoshi while the rain continued every day. Then, the pipe organ performance began, and the space from the first floor to the roof was large, so the performance and sound effects were wonderful, and this time healed and improved. On the way home, my heart was bounced, my mood was bright, and my feet were light on my way home.
Also, I wanted to come to listen to the pipe organ performance. This time, it was a coincidence, but next time I decided to check the Mitsukoshi event schedule in advance and come to listen to the performance.
From here, go to the Kyobashi 2-chome bus stop Ginza, silver bra on Chuo-dori from Ginza 1-chome to Ginza.
We will take a break at Ginza Six. My favorite is the rooftop garden.
Ginza is large, so if you walk from 1-chome, it is just 6-chome, so it is a perfect resting place. During the hot season, you can feel a cool feeling on the surface of the water.
The spacious space, greenery, window glass full of openness, and location overlooking downstairs are wonderful. I am surprised at my proximity to the sky. It's my best favorite now.
According to the antenna shop guide in Chuo-ku, we won 26 "Atenna Shop stamp rally in Chuo-ku" using "MetroLink". I was able to go around earlier than walking, so I would like to try again next year.
At the Tokyo Olympics, we hope that people around the world will know that sightseeing and shopping can be done using a free metro bus unique to Chuo-ku. We will continue to send out how to use the free metro bus so that many people will be pleased.
