ありがとうございました。申込だけして当選したらクレジットカードをつくるつもりでしたが申し込み時点でカード番号を入力するものでした。昔のwindowsではXMITを押すたびに「第３者に盗まれるのでクレジットカードの番号等は送らない方が安全」と灰色のメッセージがでたのですが今は送ってもセキユリテイが向上してるので安全なのですね。結局、今後長崎電気軌道は利用しない人生と決定しました。

After clearing customs, immigration and security go out the security exit and then into the port terminal (where you will go to reboard the ship). There is a desk in the terminal with all-day tram passes for $5US (that was the cost in March 2018). It is cash only and the cost is per person. Other posts I read said hotel concierge desks might sell the tram passes too, but I can't verify that. There is also a money exchange kiosk, exchange desk and small flea market in the terminal.

oops - forgot to answer the question about the tram travel time. The tram took about 15-20 min, but sometimes they were pretty full, so it is possible you have to wait in a line. The trams come about every 4-7 min, so they were prevalent when we were there. And we were there in March too.

Tram car runs until 23:00 - 24:00, depending on the specific line and tram stop. Can’t paste url here, but it’s on their web site in Japanese.

There's a ticket desk in the ship's terminal building. Single ticket lasts all day so you can zip back & forth to your hearts content. If you're going to the Peace Garden & Ground Zero its about a 5 minute walk to the correct stop + you have to change trams but it's extremely easy (crowded but politely so). The ticket office will give you a smashing map of the tram network and they'll circle the stops you need. Enjoy

See the map of Nagasaki. When you stand in front of old HSBC building, you 'll see cruise ship dock a few hundred meters from you. Two team stops are within walking distance from there.

Very useful to have a map, prices are cheap so don't worries, and you can pay in cash (Yen only) direct to the driver. Japanese local people has some card passes but you won't need them. Just grab one and pay in the front. Each station is well indicated everywhere in the trams. To get on a tram just look for a station (are easy to identify because of the train rails) and take it, all the lines are well connected by connection stations well indicated on the map. Just do it!
