Accidental tourist visa overstay

I came to Japan as a tourist. I planned to stay here for 10 days but I changed my return ticket date because there was still places which I 've planned to visit, so it's now 17 days. Tomorrow I'm leaving and I just discovered that my visa was for 15 days when I thought it's for 3 months, I really regret that I didn't checked it out earier... For what should I be prepared for?

Go to your local immigration office and tell them you are very sorry. Worst case, you will be banned from re-entry for one year and will possibly have more trouble obtaining a visa again.

I do not know how you can forget something that important.
Like mentioned worse case you will be banned for a year.

than next application for a visa will be more difficult since you will be in the system.

Another point is that you will be flagged as an overstayer and this can have consequences for entry to other countries also.

Overstay is not likely to be handled easily.

Take this with a gain of salt. As it is not legal advice.

Since you are planing on departing tomorrow, I would just continue with that plan. I would just do that. Yes you overstayed, but since you are in the process of exiting the country, you should be able to exit without too much fuss. Details most likely will still be taken.

Or the other option is to go to immigration and explain your case. You might all be good and fine. Or you may be detained and further questioned. Escorted to the airport for a flight, and you may miss you actual planned flight you paid for.

To repeat, it isn't legal advice.

It is completely foolish to try to pass through the exit immigration check as if nothing had happened. If you do that, you will not be considered as having presented yourself to immigration voluntarily (because everyone must go through it) so you will not be able to use the "departure order" system. Instead, you will face detention, fines, imprisonment and/or deportation, just as if they had caught you on the street in Tokyo.

Thank you all for your advise. I was really sressed that day. I went straight to the airport like I did not know the situation. When I was getting my ticket they said that I overstayed I acted like I was surprised but luckily they said I just need to pay fine and obtain new sticker. When I asked is it sometheng serious they said I just need new sticker 'couse the day was already cuted...I felt really relieved.

So if you would have gone to the immigration office, you would have been banned from Japan for a year and wasted half your day. But since you went straight to the airport, you just paid a small fine and that's it? You made the right decision.

How much was the fine?

Unless you overstayed for months or years, going straight to the airport sounds like the better move.

One never knows what �gadditional notes�h were placed on the OP�fs �gfile�h....

if you (temporary visitors) go to immigration offices ( in cities or airports), you have a good chance to get 15 days extension with 4000 yen.
4000 yen is not a fine, it is an extension fee.

No, the decision was the wrong one because there was no guarantee it would end so well. OP got lucky; the next guy who sees this on Google and tries the same trick might not.

The people who overstay in Japan get relief by marrying Japanese. The people overstayed get 6 months--1year--3 years-- PR visa. I saw lots of people with this pattern. The spouse visa does not need any qualification, skills and overstay is forgiven. I asked Japan government office why they give visa to over stayer just because they are married to Japanese. They replied that they forgive once because over stayer is married to Japanese.

I agree with Firas that the OP was lucky. The same thing "may" have happened had he gone to the immigration office the day he noticed it and appeared remorseful about forgetting something as important as this.

Since they told the OP that he "needed a new sticker," it sounds like what they did was got him to pay the fee for a 15-day extension ("sticker"), during whose validity he left so he has no record of "overstaying." (This is exactly like the case mentioned in the link provided by ken.) I hope the OP comes back to verify if this indeed was what happened (4,000 yen fee) or there was clearly a "fine."

I can understand that you forgot as a tourist. I saw many guys married with Japanese who forgot to extend visa. The guys married with Japanese think that they can do anything because they are married to Japanese.
The foreigner spouse of Japanese must be trained and educated for visa extension. One guy divorced with Japanese and he did not informed immigration about divorce and stayed till spouse visa expire. He was caught on next extension, immigration gave him Teiju visa.
I dont know why Japan immigration is soft with over stayers married to Japanese.

Yes, it was fee 4000yen for 15 days extension. I agree that was not good decision but it was the only thing that I can do at that moment since it was my first trip without parents, I was too scared of going to immigration center.....

I have almost the same situation which happened last January 08, 2019. I accidentally overstayed my Tourist Visa (single entry, 15days) for one day. I missed my flight by an hour because of the miscalculation of the Japanese timezone. The next flight (cheapest) going back to my country is tomorrow which would be my 16th day of stay in Japan. I did not have any choice but to book the cheapest flight as I don't have much money left.

On January 09, the day when I already overstayed. I went to the check-in counter to get my boarding pass and bought a stamp from the convenience store which is 4000 yen. And went straight to the immigration and filled-up some papers (which I forgot what it was all about). I remember that immigration told me to write "going back to my country". After that, they gave me a stamp of 15 days extension permit.

Does anyone have the same situation as me? I am curious because I would like to re-apply for another visa (Philippine passports need a visa) and I read that overstaying in Japan will ban you for re-entering for 1 year or 5 years. I am not sure if I overstayed or not... given I have the extension permit. Does anyone have the same situation as me and was given a visa again within less than a year?

What's the point about to ban for 1 year or 5 years or so *without advice*?

I mean, this looks like a punishment that the "lawbreaker" didn't even know, a punishment that it's not able to prevent nor to educate for the next stay. At least if the overstayer don't face a visa deny.

I can't say you're wrong, I just don't get it.
