Hanami picnic 🌸 & Farewell Party (and Surprise Birthday Party!)

Hello everyone, this is Kai
I'm guessing that this is my first blog post (it could be not, I don't remember doing the post before, maybe I have but it must be ages ago), so brace yourselves it's gonna be rough.

Anyways, as spring also arrived in Kashiwa, the cherry blossoms are blooming crazy for the past few weeks. On the 4th of April, we gathered around and held a small but amazingly pleasant picnic at the park near AORI.

oops, try again

A-ha! Perfect!





Some of us brought their own lunch box, others bought a special fish lunch box from the restaurant on the ground floor of AORI. With warm tea and food, pleasant temperature, and delightful sight of the cherry blossoms, the picnic was simply awesome.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Followed by the picnic, we had a sad but heartwarming farewell party for Prof. Tezer Esat from ANU who's been working with us from 11th of March and his wife Sevilay.

BUT!! At the same time, we also planned a Happy Birthday surprise for our Prof. Yusuke!!  He tried to hide his true age, but sadly we all know ;) Happy Birthday Sir!

Here Kosuke is handing out the farewell gifts!

It's U-Tokyo tea mug! OMG!

 Here, our new Master's member Yusuke handing out the B-present to Yusuke!

It's a stapler without the staple!! WooooooW

 Then, of course, we had a Birthday cake and a farewell cake to make our enjoyable memory of this day to an even better one ☆

As it saids on the cake, thank you so much for staying and working with us Pro. Tezer and Sevilay, and a Happy Birthday to Pro. Yusuke, I hope that the coming year for you is even more amazing and with full of new discoveries that can push the boundary of science forward!!



Well, that's it from me for the first few weeks of April.
I hope I can post this without any problems,,,if there are, please help me haha

Thank you,
Kai Leggett
