Sunshine City

The on-site experience was truly excellent; both the photo opportunities and the staff service were on par with Disney! Also, they don't accept cash on-site, but if you don't have a credit card, you can use an IC card with a maximum top-up of 20,000 yen (multiple cards can be used) to purchase merchandise. There are also small activities worth participating in for 700 yen – definitely worth checking out! Although I didn't win the grand prize this time, getting the Hachiko badge was still pretty good (though I really wanted Usachi). A minor drawback is that if you're taking the B1 subway from Higashi-Shinjuku Station, you might get lost and only see the crowd quite far away (I recommend using navigation), but I think the walking time from Shinjuku is about the same.
