People likely experienced weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Japan, Tokyo, 426 km (265 mi) away from the epicenter, the earthquake could not be felt.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry6 km (4 mi)SE of epicenterOmagari(pop: 38,800)IV: LightDaisen Shi, AkitaJapan7 km (4 mi)SE of epicenterDaisen(pop: 91,100)IV: LightAkitaJapan13 km (8 mi)SE of epicenterRokugo(pop: 18,600)III: WeakSemboku-gun, AkitaJapan17 km (11 mi)NE of epicenterKakunodatemachi(pop: 14,100)III: WeakSemboku-shi, AkitaJapan21 km (13 mi)SE of epicenterYokote(pop: 85,600)III: WeakAkitaJapan32 km (20 mi)S of epicenterNishimonai(pop: 13,800)III: WeakOgachi-gun, AkitaJapan33 km (21 mi)W of epicenterYurihonjo(pop: 76,100)III: WeakYuri-honjo Shi, AkitaJapan35 km (22 mi)S of epicenterYuzawa(pop: 44,300)III: WeakAkitaJapan37 km (23 mi)NW of epicenterAkita(pop: 307,700)III: WeakAkitaJapan38 km (23 mi)NE of epicenterSemboku(pop: 25,900)III: WeakAkitaJapan38 km (24 mi)SE of epicenterTagonai(pop: 2,700)III: WeakOgachi-gun, AkitaJapan48 km (30 mi)SW of epicenterNikaho(pop: 23,400)III: WeakAkitaJapan54 km (33 mi)NE of epicenterShizukuishi(pop: 16,300)II: Very weakIwate-gun, IwateJapan57 km (35 mi)NW of epicenterGojonome(pop: 9,020)II: Very weakMinamiakita-gun, AkitaJapan58 km (36 mi)NW of epicenterKatagami(pop: 31,700)II: Very weakAkitaJapan60 km (38 mi)E of epicenterHanamaki(pop: 94,700)II: Very weakIwateJapan61 km (38 mi)NW of epicenterTenno(pop: 22,700)II: Very weakKatagami Shi, AkitaJapan63 km (39 mi)E of epicenterKitakami(pop: 92,300)II: Very weakIwateJapan66 km (41 mi)NW of epicenterOga(pop: 25,200)II: Very weakAkitaJapan67 km (42 mi)SW of epicenterYuza(pop: 13,600)II: Very weakAkumi-gun, YamagataJapan67 km (42 mi)SE of epicenterKanegasaki(pop: 15,600)II: Very weakIsawa-gun, IwateJapan71 km (44 mi)NE of epicenterTakizawa(pop: 55,300)II: Very weakIwateJapan72 km (45 mi)SE of epicenterMizusawa(pop: 61,300)II: Very weakOshu Shi, IwateJapan75 km (47 mi)NW of epicenterMoritake(pop: 15,300)II: Very weakYamamoto-gun, AkitaJapan76 km (48 mi)NE of epicenterHachimantai(pop: 25,100)II: Very weakIwateJapan79 km (49 mi)SW of epicenterSakata(pop: 99,300)II: Very weakYamagataJapan80 km (50 mi)N of epicenterKita-Akita(pop: 31,500)II: Very weakKitaakita-shi, AkitaJapan81 km (50 mi)S of epicenterShinjo(pop: 41,100)II: Very weakShinjo Shi, YamagataJapan83 km (52 mi)N of epicenterTakanosu(pop: 20,500)II: Very weakKitaakita-shi, AkitaJapan83 km (52 mi)SW of epicenterShonai(pop: 20,900)II: Very weakHigashitagawa-gun, YamagataJapan84 km (52 mi)N of epicenterHanawa(pop: 36,900)II: Very weakKazuno Shi, AkitaJapan87 km (54 mi)SE of epicenterIchinoseki(pop: 114,500)II: Very weakIwateJapan88 km (55 mi)NW of epicenterNoshiro(pop: 52,300)II: Very weakAkitaJapan89 km (55 mi)N of epicenterOdate(pop: 69,200)II: Very weakOdate-shi, AkitaJapan95 km (59 mi)SE of epicenterKurihara(pop: 66,600)II: Very weakMiyagiJapan97 km (60 mi)E of epicenterTono(pop: 26,100)II: Very weakTono Shi, IwateJapan97 km (60 mi)S of epicenterObanazawa(pop: 20,800)II: Very weakYamagataJapan99 km (61 mi)SW of epicenterTsuruoka(pop: 125,400)II: Very weakYamagataJapan140 km (87 mi)S of epicenterSendai(pop: 1,096,700)II: Very weakMiyagiJapan426 km (265 mi)S of epicenterTokyo(pop: 8,336,600)I: Not feltTokyoJapanNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quakeThere are no user reports for this quake yet.If you felt it, be the first to report it!Compare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

It has had at least 3 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
