Is this budget for souvenirs enough?

As part of my company's recreational activity I will be going to Shinjuku, Tokyo for 5 days next month. Transportation, accomodation and food will be handled by the company so pocket and souvenir money are the only thing for me to stress about. I was planning on bringing 40k yen as budget for souvenirs to bring back home. I just want to know if this is enough.

For reference on what kind of souvenirs im planning to buy, here is the list:

•Thrift stuff (shirts, jackets, hoodies and pants)
•Anime stuff (pins, keychains, stickers, small figurines, phone case)
*Anything from Don Quijote
*Food like chocolates, candies etc.
*Anything i fancy on the way that is easy to carry back at home

I appreciate the advices and comments.
