You already know は・ひ・ふ・へ・ほ. Add dakuten ゛ and the familiar H-row becomes the B-row — sounds you will meet in bags, hospitals, bentō, shops and ordinary choices.

You already know は・ひ・ふ・へ・ほ. Add the two small marks called dakuten, and the row becomes ば・び・ぶ・べ・ぼ.
Do not rebuild the characters from zero. See the relationship. Hear the change. Let the old row help you read the new one.
The change from ふ to ぶ is easier to learn by ear than by forcing it into an English sound box. Hear the pair several times and notice how the voice switches on.

Watch the familiar は shape first, then notice the two dakuten marks.

Bentō appears across everyday Japan: supermarkets, convenience stores, station shops, department-store food halls, schools, workplaces, excursions and home kitchens.
For a learner, recognizing べんとう is useful because it connects reading, food and an ordinary decision you may actually make.
Language becomes memorable when it belongs to a real moment.

You do not need to explain everything. When the item is visible, これを おねがいします。 can turn a choice into a courteous request.
See it. Choose it. Say enough for the moment.

Everyday Japanese is often built from short, courteous exchanges. You understand a question. You choose something. You respond appropriately. The conversation may last only seconds — but it is real communication.
A small successful exchange is already part of living in the language.

At a bakery, supermarket, café or convenience store, notice one item you could choose. You do not have to speak today. Build the moment in your head.
これを おねがいします。
You do not need a long conversation. You only need enough Japanese for the next human moment.
Listen without staring at the romanization. The goal is recognition, not translation.
Read each one aloud. Notice that the new sounds are now mixed naturally with characters you already know.
Basic hiragana: 46/46 complete.
Additional sounds: 20 unlocked.
You can now connect familiar kana shapes to が・ざ・だ・ば sound families and use them inside increasingly practical Japanese.
Dakuten is complete. Next comes handakuten ゜ — a small circle that changes the familiar は-row once more.
