We recommend taking the Narita Express (N’EX) to Narita Airport.
If you take a taxi via the expressway, it usually takes about 1 hour 10 minutes to 1 hour 30 minutes, depending on traffic conditions.
The N’EX takes about 1 hour 20 minutes, runs every 30 minutes, and costs around JPY 3,000 per person.

🚫Please Note:
N’EX is a limited express train and requires a reserved ticket. You cannot ride using only a Suica card. If you board with Suica only, you will be asked to purchase a ticket on the train (20% more expensive).

ℹ️Route:

1. Take the train from Higashi-Shinjuku Station to Shinjuku-sanchome Station (1 stop, about 3 minutes).

2. Exit at Exit E10, go up the escalator on the left, walk about 20 meters, and enter JR Shinjuku Station.

3. Take the Narita Express from platform 5 or 6.
