Near Asakusa Station on the Tokyo Metro and Tobu lines, you'll find the Sumida River. The terrace that runs along the river from Azumabashi Bridge to the Kototoi Bridge on National Route 6 is called the "Sumida River Terrace."
And, the Sumida River Terrace has many stone benches, offering plenty of places to sit.
From the terrace, you can enjoy views of "Tokyo Skytree," the golden Asahi Beer headquarters, and the "Flame of Gold" object, also known as Flamme d'Or.
If you get tired of the crowds in Asakusa, it might be nice to relax while gazing at the scenery across the Sumida River.
In addition, there's a water bus stop along the Sumida River Terrace, bustling with foreign tourists.
You can take the water bus to Odaiba Seaside Park, which could be interesting with some planning.
Also, near the Sumida River Terrace, there is an indoor "Sumida Park Rest Area" that you can also consider.
Why not use it as a place to rest around Asakusa Station?
