I used to live close by, I was running 25k daily, perfect spot for running and having a chill day. There will be a lot of walking if you go by yourself, bring comfortable shoes and tons of water when summer.

It was packed, and after waiting in line for 30 minutes, I was practically soaking wet! I felt like I had to get a quick pass or I&#39;d faint!

It was a fantastic value, with all the popular attractions included! The rest was also faster with the single-pass route!

This is such a good way to explore the city with the incentive of getting a cool prize at the end! Any Pokemon fan of any age would love this, and even if you knew nothing of the franchise you can still have so much fun figuring out where the creatures are and the little puzzle at the end. I ended up doing 2 routes and getting gifts for my friends too! I honestly might do another one sometime later in my trip. The Pokemon cut outs were such high quality too, its already been a decent amount of months and they&rsquo;re all vibrant like new. I&rsquo;m glad the event lasts for so long and theres no time limit either.

I came to Osaka Port twice 10 years ago, and I found that it has not changed much after 10 years. I feel like I have traveled back to my teenage years.
The weather was quite comfortable on the day I went there. It was cloudy, there was little sun, and it was windy, but maybe because of this, the scenery was not so beautiful.
I bought a package ticket for the Aquarium KAIYUKAN + Santa Maria, 3700 per person. In fact, I regretted it a little. I should have bought a ticket for the Aquarium KAIYUKAN.
The Santa Maria runs once an hour. We came out of the Aquarium KAIYUKAN at 12:10. We waited for 50 minutes. It felt like a waste of time and we were very tired.
There are many places to visit in Tempozan, which is very suitable for bringing children.

Going to a night show is fine. It&#39;s not too hot at night, so you can see the lights. You can also watch drones and water curtain shows. Aside from the large wooden loop for hiking, any venue that&#39;s not too closed off can be seen clearly. And by the way, going in and out from the east and west without a reservation is a hassle. How can a simple thing be complicated? How can foreigners be bullied into waiting an hour to leave last, while the Japanese leave first? There are two entrances to the park, and some of the pavilions inside. You have to make a reservation for the park, then make a reservation for the entrance, and then draw lots for the pavilions, but you can&#39;t get any. There aren&#39;t even a few subway stations between the two entrances. And look how boring the show is. For over a hundred dollars, it&#39;s like joining a hiking tour.

YTV headquarters is a must-visit for Conan fans! The first floor features line sculptures of Kuro, Kogoro, and Colan, while the second floor houses Kid&#39;s SAMA! You can pick up a set of materials with your ticket, and then buy a coffee on the first floor to sit and solve puzzles! The route starts at the TV station and continues through Osaka Castle Park. The puzzles are incredibly fun, and some are so ingenious they&#39;ll leave you gasping for air! (The weather was incredibly hot, so I took note of the warnings to prevent heatstroke. I didn&#39;t have to run around in the scorching sun and still enjoyed the puzzles. ✌🏾)
