Mt Akagi: RedSuns territory
In Initial D, Mt Akagi is the home course of the RedSuns, the team of the Takahashi brothers. Wikipedia says portions of Gunma Route 4 on the mountain feature in numerous episodes. The Japanese Wikipedia also lists the Akagi RedSuns as the street-racing group based on the mountain.
The real Akagi is a stratovolcano whose highest peak, Kurobiyama, is about 1,828 m. At its centre is Lake Onuma, a caldera lake at roughly 1,360 m. Beside it is the smaller Lake Konuma, a crater lake. Akagi Shrine stands on Onuma's shore, and a small shrine sits on an island in the lake.
Gunma's tourism site describes Onuma as a summer lake with campgrounds, rental boats and small inns. Most restaurants, the main bus stop and the parking are at the south end. Hiking, including the Mt Kurobi route, is the main draw.

Getting to Akagi
From Tokyo, take the Joetsu or Hokuriku Shinkansen to Takasaki, then the Ryomo Line to Maebashi. A Kan-etsu Transportation bus from Maebashi Station's north exit takes about 30 minutes to Fujimi Onsen. A second bus continues to the Akagi Park Visitor Center. By car it is about 60 minutes from Akagi IC on the Kan-Etsu Expressway.
Some mountain roads close for the winter. Visit Gunma lists the stretch between Akagi Onsen and Konuma as closed from mid-December to early April. Check the current status before you go.

Mt Myogi: NightKids territory
Mt Myogi is the home course of the Myogi NightKids and the setting for four races in the story, according to Wikipedia. The Japanese Wikipedia also lists it as the team's home ground.
The real mountain is a jagged ridge of eroded volcanic rock on the borders of Annaka, Tomioka and Shimonita. The summit, Somadake, is about 1,104 m. It is one of Japan's 200 Famous Mountains and one of the Three Mountains of Joshu.
Myogi Shrine sits on the slope of Hakuun-zan. It is said to date from 537 and is an Important Cultural Property. Its buildings have lacquered finish and detailed carvings, and it is surrounded by cedars said to be 500 years old. Michi-no-Eki Myogi, a roadside station with a tourist information centre, stands near the shrine's first torii gate.
Hiking trails run from gentle to very hard. The rugged terrain has caused many accidents, so stay on the easier routes unless you are experienced.

Usui Pass and the C-121 corner
In Initial D, Usui Pass is the home course of Impact Blue. Wikipedia says Takumi races a SilEighty driven by Mako Sato there. A tour page on Gowithguide describes a run of tight consecutive hairpins and a corner labelled C-121, and lists Ogino-ya restaurant as a place tied to the SilEighty battle.
We could not confirm where a corner labelled C-121 is on the real road. Treat any specific spot as fan-identified until a better source appears.
Usui Pass is on the border between Gunma and Nagano at about 956 m, according to the Japanese Wikipedia. Old National Route 18 is about 11 km long and has around 184 curves. The Usui Bypass opened in 1971 and became toll-free in 2001, and the Joshin-etsu Expressway opened in 1993.
The old road is narrow with many sharp curves. English Wikipedia says it was closed for several months in 2024 because of a landslip and is popular with cyclists when open. Check the current status.

What else to see at Usui
The brick Megane Bridge, formally Usui Third Bridge, belongs to the former rail line over the pass and is a designated cultural property. The Shin-etsu Main Line crossed the pass from 1893 to 1997 and a museum now stands at the former locomotive shed site at Yokokawa. Kumano Shrine stands near the summit.
Please remember that Touge Town is an independent fan project, not affiliated with or endorsed by the Initial D manga, its publisher, studios or rights holders.
Visiting responsibly
All three places are used by residents, hikers, cyclists and tourists. Drive within the law. Racing or drifting on public roads is illegal and dangerous. Touge Town's drift day takes place only on the closed Gunsai course.
Use car parks, keep noise down near shrines and homes, and do not stop on narrow carriageways. For the Haruna side of the story see mt-haruna-akina, and for the overview see initial-d-gunma-locations.

赤城山:レッドサンズの本拠地
『頭文字D』で赤城山は、高橋兄弟のチーム、レッドサンズのホームコースです。英語版Wikipediaは、山中の群馬県道4号の一部が多くの話数に登場すると述べています。日本語版Wikipediaも、赤城山を拠点とする走り屋グループとして赤城レッドサンズを挙げています。
実在の赤城山は成層火山で、最高峰の黒檜山は標高約1,828mです。山の中心には標高約1,360mのカルデラ湖の大沼があり、隣には火口湖の小沼があります。大沼の湖畔には赤城神社があり、湖の小島にも小さな神社があります。
群馬県の観光サイトは、大沼を、キャンプ場、貸しボート、小さな宿がある夏の湖として紹介しています。飲食店、主なバス停、駐車場は南端に集まっています。登山、とくに黒檜山コースが主な楽しみです。

赤城山へのアクセス
東京からは上越新幹線または北陸新幹線で高崎へ行き、両毛線で前橋へ向かいます。前橋駅北口から関越交通バスで約30分で富士見温泉に着き、そこから赤城公園ビジターセンター行きのバスに乗り継ぎます。車では関越自動車道の赤城ICから約60分です。
冬期は閉鎖される山道があります。Visit Gunmaは、赤城温泉と小沼の間を12月中旬から4月上旬まで閉鎖としています。出発前に最新の通行状況を確認してください。

妙義山:ナイトキッズの本拠地
Wikipediaによると、妙義山はナイトキッズのホームコースで、作中の4つのバトルの舞台です。日本語版Wikipediaも、同チームの本拠地としています。
実在の妙義山は、安中市、富岡市、下仁田町にまたがる、浸食された火山岩の険しい山並みです。最高点の相馬岳は標高約1,104mで、日本二百名山、上毛三山のひとつです。
妙義神社は白雲山の斜面にあり、537年の創建と伝えられる重要文化財です。漆塗りの建物に細かな彫刻が施され、樹齢500年といわれる杉に囲まれています。神社の第一鳥居の近くには、観光案内所を備えた道の駅みょうぎがあります。
登山道は初心者向けから上級者向けまであります。険しい地形のため事故も多く、経験がなければ易しいコースにとどめてください。

碓氷峠とC-121コーナー
『頭文字D』で碓氷峠は、インパクトブルーのホームコースです。Wikipediaによれば、拓海はここで佐藤真子が駆るシルエイティと走ります。Gowithguideのツアーページは、連続する急なヘアピンと「C-121」と表示されたコーナーを紹介し、シルエイティのバトルに関わる場所として「おぎのや」を挙げています。
「C-121」のコーナーが実際の道のどこにあるかは確認できませんでした。より確かな情報が出るまで、特定の場所はファンによる推定として扱ってください。
日本語版Wikipediaによると、碓氷峠は群馬県と長野県の境にあり、標高は約956mです。国道18号の旧道は全長約11kmでカーブは約184あります。碓氷バイパスは1971年に開通し、2001年に無料化されました。上信越自動車道は1993年に開通しています。
旧道は道幅が狭く、急カーブが続きます。英語版Wikipediaによると、2024年には地すべりのため数か月間通行止めになり、開通時には自転車の人気コースになっています。現在の状況を確認してください。

碓氷のそのほかの見どころ
煉瓦造りの眼鏡橋(正式名称は碓氷第三橋梁)は、峠を越えていた旧鉄道の一部で、文化財に指定されています。信越本線は1893年から1997年までこの峠を越え、横川の旧機関区跡には現在、博物館があります。山頂近くには熊野神社があります。
