I Just Got Job Offer in Koriyama (Fukushima Prefecture)...not sure what to do...Input greatly appreciated!

Hey everyone! I hope it is okay to post this question here. I am sort of panicked. I applied for the JET Program and was made an alternate. I moved on, especially after all the groups had gone. So I was incredibly surprised and excited when I got a call from the Japanese…

"25.08
I've always been curious about this striking spherical building.
The top floor is an observation deck, and it's free.
It has a Tohoku city feel, and below Koriyama Station is a factory, its former site, and a vast parking lot.
You can watch the Shinkansen trains pass by from directly above!
My kids loved it (even though they weren't my kids)."

Piroshi Kato

"This high-rise building is directly connected to Koriyama Station and its tenants are mainly offices and a high school. Thankfully, the observation lobby on the 22nd floor is free.
As the tallest high-rise building in not only Koriyama but Fukushima Prefecture, the views are outstanding. I visited during the day, but I imagine the night view is also beautiful."
