You can also use the word "anniversary" in some cases, especially if you are celebrating the anniversary of a marriage or a business.
英語では"commemorative goods", "commemorative gift", "commemorative object", "memorabilia"または"memento"などと言います。
"Commemorative goods/gift/object"は特別な日や出来事を祝うための品物を指し、記念日や節目の日に関連して用いられ、"commemorative"が「記念の」という意味を持つ形容詞です。言い回しの例は次の通りです：
"I received a commemorative gift for the company's 10th anniversary."（会社の10周年記念で記念品をもらいました。）
一方、"Memorabilia"は特定の人、イベント、またはテーマに関連する物品を指し、よくコレクションとして保管されます。
また、"Memento"はある人や出来事を思い出させるための品物を指し、特に観光地で買うような小さな記念品を指すことが多いです。

例文: 会社の１０周年記念品をもらいました。

または
I received an item in commemoration of our company's 10th anniversary.
As a momento of the occasion, they gave him a keepsake of a small golden cup!
"As a token of our appreciation" for long tem service or on a special event...
We might expect a small ceremony wherein someone is:
" presented with a momento" or a keepsake/souvenir, as a gift.
"To mark that day in our memory..."
So whenever we see the "momento" we are instantly reminded of the occasion!
長期にわたる勤務や記念日などの
"As a token of our appreciation"（感謝の印）と言います。
"presented with a momento"（記念品贈呈）や "keepsake/souvenir"（記念品）
が贈られる、ちょっとした式典が行われたりします。
"To mark that day in our memory..."
（その日を記念して）
その"momento"（記念品）を見るたびにその大事な行事をすぐに思い出します。
When an item is given to someone for the purpose of remembering a special event or memory represented by that item, we call this a 'momento' or 'keepsake'.
An easy way to remember what these words mean is to look at some 'hidden clues' within the words.
For example, the word 'momento' looks a lot like the word 'moment'. So we can say a 'momento' is a thing given to remember a special 'moment' or time.
Likewise, in the word 'keepsake', we see two words 'keep' and 'sake'. The word 'keep' means to have something in your possession and the word 'sake' (pronounced s-EI-k) means 'for the purpose of'. So together we can understand easily that a 'keepsake' is an item given for the purpose of saving for remembering something important or special.
"When he retired from the company, his boss gave him this trophy as a momento for his many years of dedicated work."
"This medal is a keepsake from when my grandfather served in the army."
「記念品」という言葉を英語で伝えると、「souvenir」という言葉も「memento」という言葉も使っても良いと考えました。複数形は「souvenirs」と「mementos」です。例えば、「This magnet is a souvenir from my trip to Hawaii.」という文章を使っても良いと考えました。「Magnet」は「マグネット」という意味があって、「trip」は「旅行」という意味があります。
