Went there on rainy day (Mar 28), it was still beautiful, relaxing. The park itself was not too large to walk on foot. We were there when sakura trees, well, most of them, were still in early stage with thousands of buds were waiting to fully bloom. Coffee shops and toilettes were available.
Very nice park with a beautiful Japanese garden, you need to pay a small fee to enter the Japanese garden area but it’s well worth it
The only downside to the park is you can’t BBQ except for a tiny little area where everything is included for a a fixed price, a shame when there is plenty of space to have BYO BBQ areas like other parks do
Went there on a monday, some areas of the park are closed but still enjoyed walking around and watched locals fishing and playing board games. The best park in this part of osaka. If communing with nature is your bet, recharge and be calmed by this park.
