How much Yen you will suggested to prepare for staying in Japan for around 10 hours?你能帮助我吗？ So basicly, I was thinking about having a dinner in the hotel near the airport and maybe purchase some souvenirs, (around 5 pieces). And after that, I am going to purchase a light rail ticket from airport Narita to airport Haneda. How much will that be? And does the light-rail work in the mid-night? Will it be safe and how long it will take? Would anybody like to give me a rough idea how much Yen should be prepared? Thx for your help a lot ;P 你好，我将过境日本，逗留约10小时左右。我想请问如果在机场吃一顿饭再买点小礼物大概需要多少日元（Yen）？同时我还需要买一张从Narita机场去Haneda机场的车票，请问大概需要多少钱呢？午夜的电车需要多久才能到达Haneda机场呢？ 谢谢你的帮助。
