Each lesson breaks down a real sentence posted or spoken by a J-Pop artist, group, or idol. I will explain the words, grammar, and natural expressions and help you understand your faves’ Japanese in no time!
さあさあ来ました
Waterfall！！！🌊
In our first lesson, we will explore this sentence from MAZZEL’s Naoya. By the end, you will be able to read and fully understand the Japanese Naoya uses here. This is the perfect opportunity for overseas MUZE to level up their Japanese skills and get one step closer to understanding all of MAZZEL’s members.
So let’s start learning Japanese with the MAZZEL members!
Learn Japanese with J-Pop Stars #1 (MAZZEL, Naoya)
⏳ Study Time: 5-10 min
How to study Japanese by yourself:
- Read a Japanese sentence aloud
- Break down its words and meanings
- Review and level up your Japanese skills
Step 1) Learn to Read Japanese Sentences and Kanji
日本語
さあさあ来ました
Waterfall！！！🌊
1.1 漢字 (Kanji)
さあさあ 来ました
Waterfall！！！🌊
1.2 カナ (Kana)
- さあさあ
- 来ました (きました)
1.3 ローマ字 (Romaji)
- さあさあ (saa saa)
- 来ました
きました (kimashita)
Step 2) Study Japanese Words and Their Meanings
English Translation
- Here we go! Waterfall!!! 🌊
- Alright, here it is! Waterfall!!! 🌊
- Come on, it’s here! Waterfall!!! 🌊
- Finally, (the time) has come! Waterfall!!! 🌊
2.1 さあさあ (saa saa)
- Word: さあさあ
- Word Type: interjection
- Word Class: around JLPT N5
- Word Formality: casual language
| さあさあ |
|---|
| [interjection] come on, here we go, alright then Alright, let’s go! Come on, come on! |
| [interjection] here, here you go (when handing something) |
さあさあ (saa saa) means “come on” or “here we go“.
The interjection is an energetic, lively way to call attention, encourage action, or hype up a situtation.
It’s often used in performances, festivals, or anime/manga when someone is about to start something exciting or dramatic or when urging someone to get moving.
2.2 来ました (きました, kimashita)
- Word: 来ました
- Reading: きました
- Word Type: verb (past tense)
- Word Class: common, JLPT N5
- Word Formality: formal, polite language
| 来ました |
|---|
| 来る → 来ます → 来ました |
| [verb (past tense)] came, has come arrived, has arrived approached, has approached |
来ました (きました, kimashita) means “came” or “has come“.
It is the polite past tense form of the verb 来る (くる, kuru, “to come”).
- 来る (dictionary form)
- 来た (past tense 〜た)
- 来ます (polite present ~ます)
- 来ました (polite past tense ~ました)
It is commonly used to describe someone or something that has come or arrived at a place or event.
Here in Naoya’s sentence, it also carries the nuance of something finally starting or happening.
さあさあ来ました
Waterfall！！！🌊
So with this sentence, Naoya (MAZZEL) is hyping up the readers while also announcing that the time for the watch party and/or their song Waterfall has finally come. He is letting everyone know that the party has just started and urging them to join the fun.

A) Listening Practice
Listen to this song.
Can you catch the Japanese we learned today?
Source: 空気公団 〜 春が来ました
Note: In everyday speech, the i in ました (mashita) is often dropped, so it sounds like “mash-ta“. In songs, poetry, or very formal speech, you may hear it pronounced as “ma-shi-ta”, though.
B) Reading Practice
Read the following sentences.
Can you spot the Japanese we learned today?
- さよならに来ました
- アメリカから来ました。
- 日本 (にほん) に来ました。
- さあさあ、MV見る (みる) よ🫶
