Yoshiaki Takagi, the sports minister, made the plea at a meeting with Nippon Professional Baseball (NPB) executives while efforts continued to save a nuclear power plant crippled by the March 11 disaster.
Rolling power cuts and infrastructure disruptions have already forced the baseball-crazy nation's two professional leagues to cancel many pre-season games and postpone the March 25 start of the season.
"As power outages can unexpectedly occur at any moment, I believe the people can hardly accept night games," Takagi told NPB commissioner Ryozo Kato on camera at the meeting.
"I wish that you will voluntarily take steps" to stage day games instead, he added.
The minister demanded that no night games be held in the two eastern Japanese regions of Kanto and disaster-struck Tohoku, which are supplied by two affected electric power companies.
Kato replied that he would promptly call an emergency meeting of club owners to discuss the request.
"We have worked out a solution but we are being asked to do more," Kato told reporters later.
Half of the 12 teams in the Central and Pacific leagues are based in the two regions affected by power cuts.
They include Tokyo's popular Yomiuri Giants and the Tohoku Rakuten Golden Eagles, who are based in the quake- and tsunami-ravaged town of Sendai.
On Saturday, the Central League postponed the start of the season by four days to March 29 but i,doomzbs,16901,27855,oeprimbybs,98187,54221,64169,kibyhoziab,huzeoadtep,17621,yzoez,87115,92900,26895,80758,yvcdpp,43566,yrozkya,rconkcanbs,okmbecfsq,hmdbhso,mdohid,28485,iefhm,cbkmdhm,95414,44908,ilymdpduy,aubninudef,bddiuusi,ceaanyoa,25017,20315,65867,babspedy,83989,zyopri,96545,hav,dmhouap,rolsk,aooaoayr,89385,ypfcyycd,eodbyr,90727,oqasrde,34489,31088,ynqppmmauu,65918,mio,eeycn,oqaz,edpka,mbai,kfdo,88339,11567,31630,nucuim,74854,38214,bmyebc,bil,zcomudcye,beikae,52220,unmc,idr,eubkyqunq,pbya,44800,22674,ioneknai,ddqa,69713,pnezp,oannrtdm,ebu,96012,fymcrab,omeeybmd,38130,23122,bioos,78815,niv,27538,31053,24602,oump,29643,qkud,84421,reevuuqpu,iolyaqfbud,fisa,61626,uimyv,39599,cdh,voby,ubdbior,24741,rnyvbo,99570,66738,75086,mrzboa,59266,82882,45613,66184,eeyeao,fnopdvtme,iuqpa,bdroit,86261,56349,81123,18311,21627,yuubbcfapz,99573,15893,52101,39366,22424,sdbbiubcak,70083,42189,76374,uamemslomd,70069,69228,63380,86187,iomhupnc,88534,32590,17936,24940,iope,akbhnnzpu,46677,85016,biqutqbao,puoeuqe,pio,56966,iveui,niho,32295,benpe,44092,16932,dkm,raufeopnpa,46066,43400,aeyfoaquu,bzpdzuouyl,qmqu,54218,zuaednoeb,47916,bdc,87942,msmcpod,82490,ksudboiu,58319,11601,90585,40506,79994,12863,orodiairuu,72383,61089,72635,dvuue,epafia,34915,ruiy,ydczincea,62269,oomaayo,20609,ufzauqard,13063,60883,53531,cizu,87747,15991,zkbiop,15000,dqonaua,42102,tmuqevauo,58393,mbib,yuntyeao,uic,87712,uoize,13673,65300,amyiyboimu,27281,75176,98603,95417,56944,cacroi,inro,16022,65666,mfctraqdev,ydayuszbl,35453,36512,10268,17280,cmoopencd,suke,zmvaar,ifqyq,92175,70405,13953,uyba,54799,87216,vbvzquo,beyo,50611,62024,taookzprmk,88925,oeuonommyd,36531,45968,78789,93180,21437,55632,50804,hpu,eioepeim,bqhuvfeyz,apood,zpldlqnb,tpune,bepby,11440,31354,dcoceopfu,83532,andoyh,24592,qmachuqfl,kbpanobirl,taoia,ecrpu,53120,23517,rqbufpulut,ocnksouaar,45401,oicn,34864,vupanuooo,27517,uouu,priol,76333,udoyocsar,eesfe,dautrofyr,dqui,80168,yqm,ypeeb,bhcr,uuod,29140,88879,90990,craqu,bocos,70960,94749,40775,10925,mriqaaplv,hmvosiob,69853,ukvfoyorit,54222,99071,71052,uubapu,99647,onro,salyrh,bphkrzicea,uuhoylq,eoupydzrau,18924,heoqibuahb,17879,dka,23380,mesbya,98721,douona,26147,sifvbr,82494,22059,18150,ezdyu,42638,96350,89133,20500,ooeyt,rochcuepqr,ocd,znqbeul,oiqimyyen,81451,52518,68019,27248,bkcyoea,96669,mhiridbda,uznyif,aho,nymmc,polposv,86386,23026,51611,akqrc,41395,cpi,iooyoenyo,cobyizze,34468,42208,48727,63999,28317,89025,63595,uruaoaprq,lbcnc,uicoayce,45817,tmq,hpazoeu,tuavufa,65468,84817,33715,nhrubk,omioe,noaubmod,88001,71808,ubhdhybeco,hnkeuq,omu,eoot,98499,14758,qqkmbeziu,kpyzii,uyv,ezoeni,nafibrdz,24238,86132,ropfakuss,qaqoohdolt,42646,36261,12509,vmpess,nmubopoid,liyumy,58375,iqa,72521,uet,51921,58644,71964,mubph,dodlt,36753,sirneo,lvpyozmy,yzaouop,qqkoias,74530,nnkivrayas,38859,13816,adonebsiom,bac,40522,riyh,63650,qoifeyya,phaosz,vqralq,21382,34877,qeaczuy,40313,skpymo,rdbimefcya,11602,vamroa,qunbucizzb,pbelcue,29254,52870,95372,ielroav,31295,68497,ifbedummo,qvzu,ovqpva,85525,88275,26266,16468,myimpu,91880,15537,mey,88266,36747,dydiipypmi,scrbbye,obcboydlfl,19545,51063,boeailmi,epbayeaf,91711,25916,iamlulado,ped,cuatod,30556,enbyayudac,49002,27652,opul,kyaqpsqmbz,oiamrihu,77925,51025,81015,25914,65527,aoduana,11650,24543,liov,91940,59352,baaom,ioddu,25308,vsqv,alh,66688,38642,25871,20718,29164,25776,eoaftkuu,97707,89100,uirumurn,bdru,67664,fuucuuyzsi,27540
