there are many historians from china and japan have doubt on xu fu as the first japan emperor, there is a big time gap
regarding to originated from hokkien, not so possible if judged by language, geographic, and culture.
an interesting findings extract here, can be translated by google
"国人关于日本第一代天皇是徐福的说法是错误的
这个说法的错误在于历史时间上的对不上号。
我们首先要在此简单的把日本国的上古历史弄清楚一下：日本列岛发现不少旧石器遗址，新石器时代遗址更多。最早居住在日本的有熊袭人和虾夷人。而古代日本人祖先的主体主要是从亚洲北部大陆和东南亚来到日本各岛后融合形成的。
日本旧石器遗址的时间定位由于那个著名造假事件，而变得扑朔迷离，在此不再详纠。单说在日本各岛主要是东部的新石器时代遗址中，大量发现的手制黑色陶器，因上面有用绳缠在陶器四周，或用绳子整形而在器具上留下绳样的花纹图案，而被称之为“绳纹文化时期”。约从公元前五千年开始，直到公元前二世纪。单就此段日本新石器时期在时间上与中国大陆的新石器时期基本同步，而非文化的发达程度。（中国大陆新石器时期约起于一万年至四千年前）
日本这段时期虽然幽远而漫长可发展缓慢，与中国大陆的文化发展速度不可同日而语。中国大陆在公元前２０７０年夏代立国，公元前１６５１年商代立国，公元前１０４６年西周立国。虽然西方及日本历史学界出于对中华文化的另类心理，而给中国大陆的“夏商周断代工程”贴上了一个“文化沙文主义”的“意淫标签”。并且为国内外很多的“唯西方马首是瞻，唯西方所言及是，唯西方标准为唯一准绳的西化派”所接受并大加追捧！这是由于中华文化目前与西方文化相比，处于劣势所带来的必然的文化自卑现象，在此无可厚非。
言归正题，在日本那漫长而发展缓慢的新石器时期，主要生产工具是磨制石器，日本土人过着捕鱼狩猎为生的原始公社制集体生活。贫富差别不大。直至公元前二世纪左右结束。（中国大陆此时是秦朝末年，西汉初期）
而从公元前一世纪到公元后二世纪，日本开始出现以陶轮形式制成的褐色陶器，并以西部为中心逐步向东传播。因首先发现于东京的弥生地区而被称为“弥生文化”。那时日本本土的生产工具仍然是以石器为主，并以开始出现青铜器，但因青铜太过珍贵而无法普及，只能做为奢侈的祭祀用品而存在。但那时最重要的进步是出现了农耕业，以稻米为主要农作物。开始有贫富分化，并逐步形成特权贵族阶级，原始社会自此趋于终结。（ 中国大陆此时是西汉武帝末年至东汉末年）
直到公元后二世纪末年，（中国大陆三国初期）日本开始使用铁器。生产力大为提高，贫富进一步加大，剥削特权进一步完善并拱固，奴隶制开始出现，原始社会正式瓦解。但那时仍未形成完备而稳固的国家机构，只是些分布于日本列岛各地，各具有不同规模的大大小小的部落联盟。有的地方甚至仍停留在母系氏族权制时代，但因实力强大而名震一时。如九州岛北部的邪马台女王部族。
公元后三世纪后期，（中国大陆东晋十六国中后期）日本本州中部开始兴起了一个强大的部落联盟，为首部族名曰“大和”。凭借着自身强大的实力终于在公元后五世纪左右基本统一了日本。正式建立了统一的较完善的国家体系。虽然在此之时，各部落联盟之内也逐渐发展完善了各自具有国家性质的权力统冶化分，但必定不是完全统一的国家机构。大和国家的首领即称之为“天皇”。（此段时期基本上是在中国大陆的南北朝末期，公元５８１年大隋帝国建立）。
公元６４６年的日本“大化改新”，是日本奴隶制社会正式向封建制社会过渡的标志性事件。
在此啰唆了半天，只为让人先简单的把日本上中古历史时间弄明白。而国人曾广为流传的“徐福东渡，创建部族而成大和，近而统一日本，而成天皇”之说，在时间上是多么的不堪一击！也难怪日本学术界老拿这一民间拗误做为例证，而攻击我国别的许多学术研究成果，甚是让国人头疼.......
要知徐福所处年代应在公元前２１５年左右，这时期对应日本，是在“绳纹文化”末期。而大和部族兴起，又是在公元后三世纪末。那时徐福大师就算活着，应该是五六百岁的大仙儿了！他要真在，何止能成第一代日本天皇――－“神武天皇”！更应是日本的第一大神――“天照大神”了！！所以说，此论可笑，可笑，可笑。

徐福虽然不可能变成日本第一代天皇――－“神武天皇”。但是，对于其东渡是否到了日本，又是否对日本本土文化产生了重要影响，在现在却有些很是重要的实际例证来证明以上之说法的确实可信性。
１，在人类进化学方面发现，在日本“绳纹文化”末期与“弥生文化”初期交汇的公元前二世纪初期，日本考古界对那一时期的日本古墓葬内的古人遗骸，通过考古挖掘后发现了一个奇特现象，那一时期日本古人的平均身长短时间内有了一个大成度的猛然增高！由以九州与本州西部为甚，而后向东发展开去。然后逐渐固定而成为日本新代中古人类的平均身长。根据人类进化学说，此现象只能解释为：在此期间必有大量外族种群基因涌入并加入本地基因序列（通婚繁延），从而使此现象发生。而此段时期正好对应了徐福率三千中国大陆童男女乘船东渡的历史事件。
现代日本也有此类例证：在二战结束后，因大批日本青壮年士兵阵亡，美国对日本军事占领而带入的十余万美国青壮年军人，与当地妇女产生出极其大量的欧亚混血儿，即现代日本所称的“战后第一代”或“日本第二种族”。这些“战后第一代”所表现出的显著特点，就是身长十分明显的高于战前日本人，那欧化的外表肤色及发色就不说了。而这大量的“战后第一代”又与本代或本土人士通婚，而成的第二代第三代日本人，因欧洲基因的逐渐减少白化巳不再明显，并慢慢定型为现代日本人的平均身高与外貌。当然，战后日本的卫生营养等方面的改善也起到一定的作用。但不是决定作用。
２，在日本“弥生文化”初期开始出现的青铜制品，并没有按照一种技术从萌芽到发展再到完善兴盛这一发展轨迹。它的出现十分突然，并未发现代表青铜冶炼业的萌芽期所必然出现的一定数量的初期遗迹及制品。这只能解释为，这种技术完全是由外界传入，并主要由掌握此类技术的外族人具体操作的这一事实。而这又与日本古人身材突然增高的那一历史时期相对应。也就不难得出日本青铜文化与大陆文明传入有着最直接关系的结论。
3，第三种说法则是疑问型的，即“大和”部族的兴起之谜。那一时期“大和”部族明显高于同时期其它部族的统治文化，生产能力及其明显有驳于日本人口自然分布规律的繁盛人口(兵源)，又有一种祖先部族由西向东迁移而最终到达现在兴起地的传说的例子，均使得“大和”部族能在那时脱颖而出异军突起，进而凭之统一天下的历史事实充满了神秘主义色彩．也就因此有了“大和”部族的兴起至少是受到强大外力支持或加盟的结果，这一说法．那么那强大外力的支持或加盟者，是否就是由当初徐福所率领的中国大陆遗族呢？谁也说不好．但是，如果徐福所率领的中国大陆移民团真正到达了日本，那么凭借着其当时自身先进的文化技能，身形体能及众多人数等方面的优势，必然会形成一个明显优于其它本土部落文明的团体．其发展也必定会对当时的日本本土社会产生重大影响．
在此的说明，并不是要炫耀本国祖先的功劳，而是单就某个历史问题阐述自己的观点．如有不对的地方希望大家多加指正．"

that's copper era products
however, copper era turned out in japan quite LATE & it looked like turned out "suddenly"(in short period)
that let people bridged up the xu fu and jap 1st emperor story but it has a big time gap of 500-800 yrs

thanks for correction

Han tu also sounds like!

japanese language seriously affected by tang dynasty, historians also claimed that cantonese is very closed to the tang dynasty language because pronounce those poems in that dynasty with cantonese is much better than other dialects in accent, tones, rhythm,etc.

so should also crown it is doped with cantonese pronounciation. indeed, some jap pronunciation resembles a few dialects including chinese pu tong hua.

japanese appearance look like northern chinese face, like shangdong, quite unlike hokkien(southern chinese appeaance).
from geographical distance, shangdong is much closer than hokkien.

looking at the ship technology at that period, chance to cross the sea and reach japan was quite risky voyage.

some like hainanese and teochew too

there is one important role if linked the relationship between taiwan and japan, that is

Okinawa
冲绳

they don't claim themselves as japanese because jap army slaughtered them before ww2

nothing wrong to discuss the history, actually it's quite interesting to learn more.

the problem is japan govt refused to accept the war truth and mistakes made, so they intentionally changed the history books that will lead to more misconception to the future or should say even now! they still have the "lucky" sense to mask out the facts they don't want to confront.

current japanese royal family are not the descendant of xu fu but one of them claimed they are.

believe him, if god father relationship also count as descendant

there were at least 150,000 or more okinawan slaughtered before the end of ww2, jap emperor sent troops there to occupy and killed so many Okinawan just because they wore Han clothes? wondering there is military and political reason.

if Okinawa is isolated from japan, taiwan and other island issues can be unknot very easy to China! Okinawa recently also raise voice and emotionally hot to be independent!


few fishy questions here?
why japan emperor sent troops to slaugther Okinawan massively just before they surrendered in ww2? timing is fishy.
why japan didn't allow the US army stationed in other part of japan? but let them station and set up base in Okinawa after ww2? even now jap govt seems unwilling or not willing to put much effort to develop the economy there, many young okinawan have no jobs there and need to find jobs elsewhere in japan; geographically and climate sense, Okinawa is quite a good location.

thinking the similar person now:

xu fu's role to japan

similar to

Zhenghe's role to Malaysia/Indonesia

that's the point many historians claimed.

lucky that zhenghe didn't leave much effect on the language in S.E asia or the smiliar argument will come back like xu fu is the shin wu tian huang

cool story

need carbon dating and gene verification to testify. but many scientists and historian found that japanese original traits and genes are usually short in height. by tracing back their gene change period, it proved that there is reason to support they mated with foreigners(not orginal japanese) and make the gene changed in short period. but it couldn't be xu fu landing period!


in ancient chinese history, followers like family servants may also name the same surname as master, is it possible part of these 3000 followers adopted xu fu's name to extend his effect on that era like god to primitive japanese; so later japanese praised him like god.



there is a saying that xu fu landed in Guan too.

could be one of the ship lost way and drifted there.

LSD?

enlightened our 2cents knowledge please

japanese like hokkien...........

should be due to the ming dynasty japanese pivates(incl govt) ripped the china coastal line, especially fu jian province.

they need to understand or probe the situation in coastal line before they landed, so it could be the reason they mingled with hokkien, and the hokkien language mixed with japanese.

so TS will have the conclusion jap first emperor is hokkien.

old japanese language content was not rich or well developed like nowadays.

when sun yat sent formed the govt, he had two languages to choose as national language
one is mandarin
another is Cantonese NOT Hokkien

the movement, the people, the bases were mostly involved with the southern chinese and in guangdong province, he himself is also originated from cantonese; to ease the communication among them and the cabinet, there is no point to choose hokkien.

however, he has been in penang, so he knows some hokkien is possible

in many of his public speeches, his strong cantonese accent can be spotted out obviously.

here is one of his public speeches with cantonese accent

scientifically not matching in timing! oriental historians also disagreed xu fu = sheng wu tian huang



more important is the truth of the history japanese preferred.
we treat their ww2 military leaders as criminals but they treat them as heros and legendary, set in a prestigious temple with grace tombs! that's what we cannot understand and accept neither! so how they praise xu fu and respect him is also their individual preference.

a govt can rewrite and change history books will give many ???? to the history and readers!!!


language evolution involved not just in writing, interpretation, and also have "pronunciation"! pronunciation is most likely to be affected. a good example is the singlish, mixed with different dialects, met a guy who can compose a sentence in hokkien, teochew, cantonese, english, malayu pronunciation, which they feel "ziouk" about it. then should claim he is hokkien ?

no linguistics can prove what is the pronunciation of a languages and dialect how it speaks in the past. some said tang dynasty speak the languages like cantonese, some said like hokkien, but no one can record it at that era!
that leaves many literature fans have more different saying on support of their speaking languages and dialects.

the interaction of the cultures, economy, literature, dressing, eating, living among different travelers or migrants will contribute the speaking languages evolution.

current japanese also getting more english like pronunciation words, so after an century some will also say their ancestor speaks english and may have foreign breed..

if we judge a language content after its long existence time, it is not easy to single out the dominance so easy due to the cultural interaction.

it is just a result of certain era and a part of the evolution of the language.

seriously, can't agree with it though our chinese is not good; the word meaning from a few reputed dictionaries is not the meaning you interpret or you found this word meaning in japanese dictionary?

here is a typical findings about this word
