One of Tokyo’s most famous nightlife sections is Roponggi, where bars, clubs, and discos that specialize in serving foreigners are open until 4-5am. But if you want to start your night earlier, you can visit Shibuya first where, like Roponggi, there are available English pubs with reasonable prices. You can also go to Japan’s largest red-light district, Kabuchiko, found in Shinjuku (which is also home to a massive gay bar district). Happy hours throughout Tokyo usually happen between 5-7pm during weekends and up to 9:30pm during the week.
