Bought on its own it is a US$11.25 aquarium. Added to a LEGOLAND Japan ticket the listing puts it at JPY 800. Which door you come through is the whole decision here - and 46 reviews tells you the rest.

The listing suggests five to seven hours, the park sits on reclaimed land away from central Nagoya, and there are two ticket tiers plus a JPY 800 aquarium add-on. This is a day to plan, not a stop to fit in.

The set ticket pairs Sumida Aquarium with the Tokyo Skytree deck, and the listing is explicit: climb the tower first, and redeem both at the 4F counter. You also have to pick a Skytree entry time when you book.

The listing says you may re-enter as many times as you wish on the day of your visit - and the Stadium show changes from day to night. Those two facts together are the reason to plan this one differently.

Tokyo's rooftop aquarium runs a numbered-ticket reservation on its own website. The listing says plainly that visitors booking this ticket do not need to do that - which is the whole reason to book it this way.

The castle's own website says it on the front page: the tower keep cannot be entered. What you walk into is the reconstructed Hommaru Palace - and the official site publishes its live waiting time. Here is what the ticket actually gets you.

It is Nidec Kyoto Tower now, the deck is at 100 meters, and the listing itself tells you to book ahead to avoid the line at the booth. Here is why a short tower gives Kyoto its best view.

Tsutenkaku is not one attraction with one closing time. It is four, and the two people actually come for shut hours before the tower does. Here is the timetable that decides when you should arrive.

The Ikebukuro observatory people still call SKY CIRCUS is now Tenbou Park, and its e-ticket comes with rules that will stop you at the door: it needs internet to open, and if you operate it yourself it can read as used.

Tokyo City View starts at US$7.49, which makes it the cheapest of the big Tokyo views. What that buys is the 52nd floor. Whether the rooftop comes with it depends on the option you pick, and the listing does not spell it out.

HARUKAS 300 sits on floors 58 to 60 of Japan's tallest building complex - one deck open to the sky, one behind glass. Last entry is 21:30, and there is at least one evening when a regular ticket will not get you in at all.

The Kuchu Teien Observatory is one of the few open-air rooftops in Osaka, which means weather decides your visit more than availability does. Last entry is 22:00. Here is how to time it and what the ticket actually covers.
