Funmock Panza Miyazawako Metsa Hanno insaitama (5) Metsä

Funmock; an athletic in the sky

Panza is the name of the company, Miyazawako the name of the branch, Funmock is the name of the play area and Metsa Village (Hanno) is where it is located!

Panza Project Adventure Japan

Panza is part of a larger collaborative called Project Adventure Japan. There are Project Adventure Foundations in several countries including America, Australia and New Zealand. Toshio Hayashi founded Project Adventure Japan (PAJ) in 1995.

Before going to Funmock today, I was searching online for accounts of people’s personal experiences at Panza, but surprisingly couldn’t find even one article in the English language. I did however find a very interesting piece from 2003 about Toshio Hayashi and Project Adventure Japan. It explains the concepts and policies behind the incentive.

Panza Miyazawako

There are a few Panza dotted around the country. The branch in Hanno is called Panza Miyazawako. It is a relatively new addition to the Project Adventure family of outdoor nature based learning through play and sports in Japan.

Panza Miyazawako is based at the Metsa Village, the Finnish theme park and home to Moomin Valley, in a rural area of Hanno City. The play area that this branch of Panza offers is called FUNMOCK, a contraction of fun and hammock. It opened on April 18th this year, 2019.

The entrance to Funmock is located within Metsa Village on the way to Moominvalley, opposite Lake Miyazawa and in the forest on the hills. It is after the blue Nordics building and before the Starbucks just at the Metsa Hall, where there is currently a Christmas market.

Funmock in Metsa

Funmock is an adventure playground for both adults and children. It is made entirely of rope and suspended from trees. There are ten chambers within the play area, including a lower floor chamber, which is reserved for children under two. And there is a space on the ground too under the netted play land, with hammocks for chilling out in and great views of Lake Miyazawa.

One of the chambers has large balancing balls to play with, another chamber has balls tied up high for kids to jump up and touch. Two of the chambers have upper chambers which you can climb up to and use the slides that go back down to the lower chamber.

Its like a humongous trampoline in the air, with two floors and slides also made of rope. It does feel a bit weird when you enter the play area. I felt for a few minutes like the netted rope below might give way or that the pressure would create a large hole. It didn’t and after a few minutes the feeling went away.

The System

The Nordics blue building at Metsa beside funmock

There is a small reception area beside the Metsa Hall right after the Nordics distinctive blue building. Here you fill out a disclaimer form with your name, address and an emergency contact number. After filling out the form you walk up the hill to the reception building, where you pay for your desired play period.


You can play for half an hour, an hour or 90 minutes. For children under 12 parents must also pay to enter and accompany a child/ren. There is no charge for children under two years old. The sessions are started on the hour or half hour from 10 am, but reception starts from 9.30 am. On a weekday you don’t need to have a reservation, but on weekends, public and school holidays it is recommend you book in advance (click for the booking form).

SessionAdult / child 7+ years old Child’s price (2 to 7 years old)
30 minutes1000 yen1000 yen
60 minutes1500 yen1000 yen
90 minutes2000 yen1000 yen

Its advised to arrive about ten minutes before a session starts as there is a short explanation of the rules before you start to play and after you pay. The waiting area where they explain the play area is up another hill from the reception building.

There is a large tent with chairs and hammocks you can use while waiting or as a rest area. You can bring water and a towel to this area, but it is advised to leave hand bags and larger items in the lockers at the reception building. The lockers are free to use.

Funmock Rules

you can borrow shoes at funmock in metsa hanno

They are not particularly strict from what I can tell, but they do give you a run down of how to play safely. They don’t forbid you from wearing heels into the play area, but there are flat shoes you can borrow in the reception building so you can play easier.

Funmock corridors are marked by red net

The main rule that the enforce is that there is no jumping in the corridors of red net nor on the upper floors. They also ask parents and adults to be careful of children when jumping as the bounce we create can send children flying!


We enjoyed Funmock more than we expected. It was a really good work out too. I hadn’t expected to exert myself so much, next time I will bring a change of T-shirt! The kids loved the novelty of it. They have played in tree top adventure playgrounds before, but this is quite different with you being suspended.

If you are not in the mood for a work out, there are places you can chill out. There is a chamber within the netted sports adventure playground where you can just sit or lie down or you can use the hammocks on the ground and there is also the tent area just beside the entrance to the play area.

Steep slide from nets at Funmock

The kids really loved the netted slides. You climb up to them from nets too. There is one that is really steep. I had to pluck up the courage to go down it, but I am so glad I did. The kids were sweating after their session as was the staff member who spent the whole time playing with kids, which I thought was really commendable and sweet.

To be honest about 40 minutes was enough for me and my five year old. If I hadn’t jumped and climbed so much I probably would have been able for longer. Older kids would probably enjoy an hour or the longest session of 90 minutes, especially if you are taking breaks and using the hammocks and / or rest areas.
