Japanese isekai that I like ONLY

We can't start an isekai list without TenSura, it's too iconic. Tho, some people can't take the wordy chapters so for newbies, the Anime is a good start.

Summary: Man died from being stabbed, got reincarnated into a slime in another world. And took the entire universe by a storm (hehheh).

A healthy balance between slow life and fighting actions.

Currently favourite Japanese isekai manga related to cooking. Weak MC, Delicious food, Awesome nakama, Slow life

Summary: A guy gets involved in a summoning circle accidentally. Seeing that the royalties are suspicious, he YEETS himself out of there. Finding companions one by one, he travels the world and living an awesome life.

I absolutely adore that the elf character is definitely... unique? Yeah, that, LoL. THERE'S ANIME

This is a spin-off to the manga above!! It's everything from SUI'S PERSPECTIVE It's absolutely ADORABLE and if you like the original, this is a must-read!!

Nice MC, OP MC, Slow life, Anime is maybe ok, but it's too family-friendly, they cut a lot of important stuff.

Summary: MC died from head concussion, selected for reincarnation. After 3 years of living in the forest alone with his tamed slimes, he met people who then changes his life for the better.

Since it's a slow life manga, there's not much fighting, so maybe it's not some people's cup of tea.

The answer to all the questions are BEARS. That's all there is. Isekai, Cute Flooff, OP MC, Anime

Summary: Girl playing a VR game, got a Bear Set as a gift, then suddenly got isekai'd with nothing but the bear set. Only when she's wearing that bear set, she's super OP.

Harem: (well she does have a small fanclub tho)

Anime is also good as a starting point, but it's also family friendly.

It's a really graphic anime/manga, since MC is a monster. Isekai, MC level up, OP MC, Action heavy, Anime

Summary: MC's classroom somehow exploded, all the students in it got isekai'd into the same world. But somehow, MC is reincarnated into a spider monster.

Anime is actually non-linear, I think it's following the light novel? Everyone isekai'd at the same time.

I envy and pity the MC at the same time LoL. Strong MC, Dungeon, Useful girl sidekick

Summary: A dungeon appeared in MC's garage in a rural area. After obtaining a skill board leveling system, he became stronger at an absurdly fast pace.

Harem: so far

MC's reactions to critiques and hate comments are just so pitiful but entertaining nonetheless. You just can't hate him

What's better than getting isekai'd to a new world? Getting isekai'd with your entire family, that's what.

Summary: After fainting from eating strange mushrooms, the Stuart family suddenly remembered their past lives as Tanaka family. They even met their cats from before (they turn into giant cats)! This is just a story of a family TRYING to live their lives peacefully.

If you're afraid of bugs, then maybe it's not your manga.

Isekai Slow life Slice of life

Summary: MC is reborn into a high elf. He strives to make the best out of his life, alongside his loved ones, no matter the difference in lifespan.

This manga evokes feeling you won't ever feel in other manga, specifically the flow of time. MC is a high elf, with the longest lifespan in among all creatures. The timeskip between each chapters could be 2 years, or 20 years.

Summary: Ever since waking up as a baby, MC was raised by three undead creatures on a deserted place. After an incident that took the lives of his parental figures, he set out on a journey to see the world, alongside his oath to his chosen God.

(Sadly some of the chapter are divided in 4)

So far, it's very interesting to read. Anime is available now.
