Hi, I'd recommend you to visit "Gohyaku Rakan-ji" temple located near "Fud-mae" station of Tokyu Meguro line. When coming, you can take JR Yamate line and transfer at Meguro station to Tokyu Meguro line. Fudo-mae is the next to Meguro. (Take local train as rapid ones skip Fudo-mae)
Gohyaku Rakan-ji displays more than 100 statues of Buddhism (English guide on digital displays are available) Next to the cozy temple is the huge Meguro Fudo temple. You can observe the solemn main hall with many ornaments and more.
Just for your info!
I do love to go to Jindaiji. It will take around 1 hour from Shinjuku. So we feel like a small trip. There is nature, temple, cultural events, cosy shops and famous soba. This is Japanese website http://www.jindaiji.or.jp/ this is summarized English site. www.jindaiji.or.jp/language/english.pdf
How about Sensoji Temple and Zojoji Temple?
Asakusa can see the sky tree while riding a rickshaw and Zojoji can be seen with Tokyo Tower.
It is recommended that the light up of the night is beautiful.
Because there are also many tourists, I think that English can be communicated somewhat.
