I am not sure what exactly this phrase means in Japanese, so there are a few different possibilities for an English equivalent. A travelogue is a memoir written by another traveler. A travel journal is a log meant for writing about your own travels. However, a book with information about a particular graduation is simply called a "travel guide."
A travel log is a popular name for a record of someones travels, it usually includes information about someones travels, whether that is places they have visited, thoughts on their travels, pictures or memories of their journey.
You can also refer to these logs as 'travel journals' or 'travel diary'.
'I am going to keep a travel log of my trip so that I can remember the good times'.
旅行記は、旅行を記録する人気のある呼び方です。
通常、訪れた場所や旅行中考えたことや写真や思い出などに関する情報も含まれます。
また、これらの記録を「travel journals」や「travel diary」ということができます。
I am going to keep a travel log of my trip so that I can remember the good times.
その良い時間を覚えておくために旅行記をつけ続けています。
Travelogue may refer to - Travel documentary, a documentary film or television program that describes travel in general, or,
Travelogue (literature), a record of the experiences of an author travelling.
A private individual may keep a travel log and a person wishing to share their experiences with others using video may do so by having a travel VLOG.
Here we can interchangeably use the words, "journal or dairy," to talk about a book in which we write stories of our adventures.
Examples:
I write in my travel journal almost every day.
I love keeping a travel diary to write about my adventures.
