5. Essential Shinjuku Travel Tips (Revised)

• ・Station Navigation: Shinjuku Station’s numerous exits are famously confusing. Aiming for the “South Exit (Busta Shinjuku side)” or the “Southeast Exit” is generally simpler, as they lead directly to the main Koshu Kaido street.
• ・Meeting Points: The “Alpina Screen” at the East Exit is famous but extremely congested. The “Shinjuku Eye” sculpture (a huge eye-shaped object in the underground West Exit plaza) is a clearer, less crowded alternative for meeting friends.
• ・Using the Underground: The vast underground shopping area in the West Exit allows you to access major buildings and exits without getting wet during rain.

Summary

Shinjuku is a dynamic, multilayered metropolis where ultra-modern technology coexists with nostalgic culture and extensive green spaces.

The smartest strategy is to combine the TST (for Marunouchi/Oedo Line subway travel) with an IC Card (for JR Lines and Private Rail). Choose wisely between the East and West sides based on your travel goals, and fully experience Tokyo’s legendary energy.
