Onoda yavukiye mu Buyapani mu 1922, aza kwinjira mu gisirikare cy’iki gihugu mu gihe Intambara ya Kabiri y’Isi yari irimbanyije. Mu mpera za 1944, yoherejwe ku kirwa cya Lubang muri Philippines afite inshingano zo gukora ubutasi no kurwanya ingabo z’abanzi.
Mbere yo kugera ku rugamba, umuyobozi we yari yamuhaye itegeko rikomeye cyane. Yamubwiye ko atagomba na rimwe kwishyikiriza umwanzi cyangwa kwiyahura, ahubwo ko agomba gukomeza kurwana kugeza igihe azabonera andi mabwiriza aturutse ku buyobozi bwe.
Mu 1945, Intambara ya Kabiri y’Isi yarangiye nyuma y’uko u Buyapani bwishyikirije ibihugu byari bihanganye na bwo. Indege zatangiye kujugunya impapuro mu mashyamba no mu duce twagenzurwa n’abasirikare b’Abayapani zibamenyesha ko intambara yarangiye.
Ariko Onoda n’abo bari kumwe bakekaga ko izo mpapuro zari amayeri y’abanzi agamije kubashuka ngo basohoke bihereze. Kubera iyo mpamvu banze kuzemera.
Mu myaka yakurikiyeho, abaturage bo muri Philippines, abapolisi ndetse n’abasirikare bagerageje kenshi kubabwira ko intambara yarangiye. Hari n’abanyamuryango b’abo basirikare boherejwe kubahamagara bakoresheje amajwi n’indangururamajwi.
Nyamara Onoda yakomeje kubifata nk’uburiganya. Yari yarafashe icyemezo cyo kutazigera ava ku nshingano yahawe kugeza igihe azabwirirwa n’umuyobozi we ubwe.
Bamwe mu basirikare bari kumwe na we bagiye bapfa cyangwa bagafatwa uko imyaka yicumaga. Amaherezo, Onoda yasigaye wenyine mu ishyamba ariko ntiyacika intege.
Yabayeho imyaka myinshi arya imbuto zo mu gasozi, ibitoki, coconuts ndetse rimwe na rimwe akica amatungo y’abaturage kugira ngo abone ibyo kurya. Yari agifite imbunda ye, imyenda ya gisirikare ndetse n’icyizere ko igihugu cye kigikomeje intambara.
Mu 1974, imyaka 29 nyuma y’irangira ry’intambara, umusore w’Umuyapani witwaga Norio Suzuki yafashe urugendo rwo kujya kumushaka. Nyuma yo kumubona no kuganira na we, Onoda yavuze ko atazava mu ishyamba keretse abonye amabwiriza aturutse ku muyobozi wamuhaye inshingano mu 1944.
Icyo gihe leta y’u Buyapani yashatse uwo wahoze ari umuyobozi we, Major Yoshimi Taniguchi, wari warasezeye mu gisirikare. Yamujyanye muri Philippines kugira ngo ahure na Onoda.
Ku wa 9 Werurwe 1974, Taniguchi yamusomeye itegeko rimukuraho inshingano za gisirikare kandi rimubwira ko intambara yarangiye kera. Ni bwo bwa mbere Onoda yemeye ukuri.
Nyuma y’iyo myaka 29 yose, yashyize hasi imbunda ye, akuramo imyenda ya gisirikare yari amaze imyaka myinshi yambaye, maze ava mu ishyamba nk’umuntu wari umaze hafi imyaka itatu y’ubuzima bwe bwose yitegura intambara itagihari.
Icyatangaje benshi ni uko imbunda ye yari igikora neza, ndetse yari akibitse amasasu n’ibindi bikoresho bya gisirikare. Agarutse mu Buyapani yakiriwe nk’intwari n’abaturage benshi, nubwo hari ababonaga ko ubudahemuka bwe bukabije bwari bwaramubujije kwakira ukuri igihe kirekire.
Hiroo Onoda yapfuye mu mwaka wa 2014 afite imyaka 91, ariko kugeza n’uyu munsi akomeje kwibukwa nk’umwe mu basirikare bagaragaje ukwizera gukomeye ku mabwiriza bahawe kurusha abandi bose mu mateka ya gisirikare.
Inkuru ye ikomeje gutangazwa mu bitabo, inyandiko n’amafilime nk’urugero rw’ubudahemuka budasanzwe, ariko nanone ikanibutsa abantu uburyo amakuru atizewe cyangwa kutemera impinduka bishobora gutuma umuntu amarana imyaka myinshi ukuri kure.
